If enterprises want to survive and develop, they must rely on quality products to achieve. Excellent product quality and service quality can bring benefits and development to the enterprise, bringing prosperity and strength to the country; and inferior product quality and service quality will cause great waste of resources, eventually leading to the existence of the company... the famous American quality In 1994, expert Zhu Lan pointed out in the farewell speech of the annual meeting of the American Society for Quality Management: The Century of the Century is in the annals of history, and the future 21st century is the "century of quality."

It can be seen that improving product quality is an inevitable requirement for enterprises to remain invincible in the market. To improve product quality, we must not only have advanced technological advances, but also scientific management. Technological advancement provides strong support for improving product quality, while quality management can effectively implement technological advancement and provide assurance for improved product quality.

Beneficiation plant since the operation, especially in recent years, focusing on both technology and management, when its survival and long-term development combine to total quality management naturally fully reflected. As a result, the production capacity of the concentrator has been greatly improved, especially the quality of iron concentrate has made a qualitative leap. The grade of iron concentrate was increased from 59.8% in the 1990s to 1.51% in fluorine, 66.08% in iron recovery, and 144t in rod mill. The iron concentrate grade was 64.89% and the fluorine content was 0.36%. 74.17%, the rod mill has a processing capacity of 203t.

Total Quality Management is based on quality, based on full participation, and through the management of the entire process of the organization, the pursuit of lasting success of the organization, so that customers, the owners of the organization, employees, suppliers, partners or social stakeholders continue Satisfaction and benefit. It usually includes the development of quality guidelines and objectives and quality planning, quality control, quality assurance and quality improvement. Here's a brief description of how the concentrator can achieve these processes:

First, the quality policy and objectives

The leaders of Baotou Steel Concentrators attach great importance to quality management and firmly establish the idea of â€‹â€‹â€œquality firstâ€ in production and operation. The director personally issued the quality policy of â€œsound system to maintain concentrates and keep up with the timesâ€. Develop advanced and feasible quality objectives based on company requirements. The quality objectives of the 2005 concentrator are:

The annual average grade of integrated iron concentrate is â‰¥64.8%;

The average grade of rare earth rare earth in strong magnetic field is â‰¥10%;

The average grade of rare earth rare earth ore is â‰¥8%.

Through the formulation of the quality policy and objectives, the quality objectives and quality direction of the concentrator are specified, so that the production organization, scientific work, and quality work have rules to follow.

Second, quality planning

Quality planning is focused on setting goals and defining the necessary operational processes and related resources to achieve quality objectives. The key is to set quality objectives and manage them, and usually set quality objectives for the relevant functions and levels of the organization.

The concentrating plant holds the quality committee headed by the director and chief engineer at the beginning of each year to discuss and pass the "Quality Work Plan" and the "Qualification Standards for the Process of the Concentrator" and the "Measurement Methods for the Quality Indicators of the Concentrator" to further clarify the quality objectives. Each production workshop and related departments shall set their own quality targets. At the beginning of 2005, in the "Quality Work Plan", the theme of "Improving the physical quality of iron concentrates" was defined, and the quality of "supervised, inspected, spot-checked, and evaluated" as the means to unswervingly follow the path of quality and efficiency Work guidance. In the "Measurement Methods for Quality Indicators of Concentrators", the quality objectives of each workshop are specified. For example, the quality target of the crushing workshop is: the pass rate of the two types of grain reaches 98%.

Third, quality control

Quality control is committed to meeting quality requirements and is a process that ensures that the products produced meet the requirements. This is particularly evident in the concentrator's operation as a secondary mine in Baotou Steel.

(1) Timely development of quality standards and assessment methods

At the beginning of each year, the concentrator held a quality committee in time to convey the quality tasks assigned by the company to the concentrator and discuss the quality standards and assessment methods for the various stages of the concentrator to complete the task, thus laying a solid foundation for the completion of the quality objectives of the concentrator. .

(2) Strengthening process control

In order to ensure and improve the quality of iron concentrate, the concentrator pays special attention to process quality management, establishes process management points in key processes and weak links, strengthens process management point control, and adopts the operation instructions for the technical, management requirements and assessment methods of the process. The form was sent to the post, which clarified the operational points of the post personnel and improved the control ability of the process quality. At the same time, the inspection workshop will carry out special inspections on the process management points of each workshop, and promptly rectify the workshops in response to the problems found; carry out random inspections on the quality of the workshops, and conduct strict assessments on workshops that fail to meet the quality standards; The workshop is required to carry out self-examination, and the inspection workshop shall check the self-inspection at any time and incorporate the daily quality assessment of the workshop. In addition, at the beginning of each month, a detailed summary, analysis, and necessary assessment of the process quality of the entire plant will be carried out. In order to improve the quality of the process and ensure the quality of the iron concentrate, the concentrator has carried out the â€œthree-stepâ€ activities of â€œstrictly accepting the process, carefully controlling the process, and the process of quality serviceâ€, and resolutely demanded the upper and lower processes in each workshop and the same workshop. Inter-communication between the two, each of which makes a good record, and effectively rectifies according to the opinions put forward in the next process.

(3) Strictly control the quality of raw materials entering the factory

For the people's factory pharmacy, ore, and the purchase of concentrates, the employees with high consciousness and high-quality business are inspected for quality, strictly sampled and tested according to the regulations, and provide accurate quality data to provide strong guidance for production. For those who are unqualified, they will be punished in addition to the refusal.

(4) Strengthening quality information feedback

Quality information is the basis and basis for quality management. It not only helps to identify quality problems, but more importantly solves quality problems. For many years, the concentrator has established a sound internal and external quality information management network centered on production scheduling. In the internal quality information transmission and feedback, adhere to the principle of timely, accurate and fast, and transfer the quality information to the post, so that the post personnel can adjust the operation in time to ensure the quality of the process is up to standard. In order to further improve the information feedback speed of iron concentrate grade, IED-400 fluorescence analyzer and IED-2000P XRF rapid analyzer were introduced. The instrument was used to analyze the iron content for only 2 minutes. The content of silicon, sulfur and potassium was measured for 6 min. It is obviously faster than the chemical analysis to speed up the analysis and stabilize the iron concentrate grade and control the impurity content. Strengthening the feedback of quality information is also reflected in the dispatch meeting every morning. The workshop is required to report the quality of the iron concentrate and the quality of the process and the production technical measures adopted. The factory leaders make a summary of the quality of the previous day and put forward requirements for the quality of the day.

(5) Timely analysis and summary of quality status

In order to accurately reflect the quality of the production process, the concentrator has been insisting on producing a daily production and operation daily report, most of which is related to the quality of iron concentrate and the quality of the process, and also requires the ex-factory and workshop-level reports. Monthly report, timely quality analysis and monthly quality analysis, summarizing advanced, insufficient search, timely rectification, thus forming a benign quality cycle with daily insurance and ten-day warranty.

(6) Improve the basic work of quality management

For many years, the concentrator has been constantly working on the basics of quality management. In the formation of process discipline, strict requirements, serious treatment of violations, developed a detailed "violation and violation management system", established a three-level management system of factories, workshops, and teams, while stipulating violations at the company, plant, and workshop levels. Violation of projects and assessment measures, through years of management, inspection, supervision and assessment, to prevent the occurrence of violations at the company level, the violation of regulations at the factory and workshop levels has been reduced year by year; in the management of quality accidents, resolutely pursue quality accountability The system is responsible for all economic losses caused by the department in which the quality accident occurs, and the leaders of the department and related personnel are held accountable for leadership. Over the years, company and factory-level quality accidents have not occurred; at the same time, in order to accurately grasp the true level of physical quality, the mineral processing plant group's physical quality self-examination activities. When the quality of iron ore concentrate fluctuates, random inspection, tracking, re-inspection, etc. are carried out in time, and the problems identified are promptly rectified to achieve effective monitoring of the quality of iron concentrates. In addition, the concentrator insists on conducting visits to the factory activities in order to make the iron concentrate quality better meet the user requirements while requesting exchanges between the processes. Every year, the factory leaders led the relevant personnel to visit the ironworks in person, humbly take the opinions of the users, carefully analyze the opinions of the users, and actively take effective measures, which could not be solved at that time, as the direction for future improvement.

Due to the strict quality control performed by the concentrating plant, the company-level physical quality and process quality spot checks are all qualified, and the quality indicators at all levels are successfully completed to complete the company's assessment plan, providing high-quality materials for iron making, thus creating huge economic benefits for the company. .

Fourth, quality assurance

Quality assurance is committed to providing the trust that quality requirements are met. Quality assurance and meeting requirements are the basis and premise of quality assurance. The establishment and operation of quality management system is an important means of providing trust.

A sound quality management organization with clear responsibilities is the basis and prerequisite for establishing a quality management system. The ore dressing factory has set up the director with the director as the director, the chief engineer and the deputy director of the production as the deputy director, the heads of the departments and the workshop directors as the members of the quality committee, responsible for the formulation and implementation of the quality policy and quality objectives of the factory and the major The quality problem is decided; the inspection workshop is responsible for the daily quality management work; each workshop has established a quality management leading group to form a three-level quality management network. At the same time, it has improved the quality responsibility system of all functional departments, leaders and workshops of the whole plant, and required the workshop to refine the quality responsibility to the work sections, teams, and posts, and effectively decompose the quality work tasks into the workshops, departments, and personnel at all levels. It has achieved the indicators on everyone's shoulders, thus forming a good atmosphere for everyone to care about quality.

The concentrator has established a relatively complete quality management system, actively promoted and implemented the IS09000 standard, conducted the study of the IS09000 standard, analyzed and discussed the quality elements, determined the quality loop, and compiled the quality manual, procedure documents and related quality management system. And continue to improve in the operation of the quality management system to ensure that the production process of the concentrator is under control, to ensure that the final iron concentrate quality meets the requirements.

Fifth, quality improvement

Quality improvement is dedicated to enhancing the ability to meet quality requirements. It can be seen that quality improvement involves all aspects, taking into account all factors that affect quality, including technical, managerial and personnel aspects. Every year, the technical transformation carried out by the ore dressing plant, the small reform of the small leather, the introduction of new equipment, new materials, and even the education and exchange of employees with strong professionalism and high education level are regarded as quality improvement. The successful practice of grinding and re-selecting the process in the past two years is a good example of the quality improvement and expansion of the survival and development space of the mineral processing plant.

It can be seen that quality improvement in the ore dressing plant can be described as endless, and it is not uncommon, in order to improve product quality and enhance the company's stamina.

Sixth, the conclusion

Quality is the foothold and destination of all work in the enterprise. Therefore, continuously improving the physical quality of the iron ore concentrate of the ore dressing plant is the inexhaustible driving force for the ore dressing plant to advance in the market economy. Quality work is becoming more and more mainstream in the work. So, what aspects of the future quality work of the concentrator should be optimized?

(1) Give full play to the role of human resources. Because people are the most active factor in productivity, they should be given the duties and authority of all departments and positions to create a good working environment for all employees and encourage their creativity. And enthusiasm, not only to carry out quality awareness education, but also to educate them on quality and technical knowledge, to increase their talents and capabilities, to bring maximum benefits to the concentrator.

(2) The quality work needs to be further refined. The work should be carried out in strict accordance with the quality requirements. The quality documents should be supplemented and improved as needed, and incorporated into the standards as much as possible. In other words, continue to work hard to "do what you write and write," so that quality management work is enriched and improved.

(3) Implementing quality and economic management. For the concentrator, the cost of identification accounts for a considerable proportion of the cost of quality. If possible, can we consider reducing the frequency of process and physical quality testing, and ultimately reduce the quality of the concentrator? investment.
