Heat treatment process, a new method of quality control

It is well known that heat treatment is by changing the material organization make mechanical parts or products to obtain the required performance and ensure the use of safe and reliable process, is an important part of mechanical manufacturing engineering. Because of the heat treatment quality characteristics is the result can not be completely is obtained by subsequent inspection and test validation, and heat treatment once appear quality problem caused by the negative impact and economic loss is very big, so in GB/T19000 series standard, the heat treatment was identified as 'special', need to take special measures, implementation of full, all-round, the whole process of quality control. Due to domestic companies heat treatment equipment, personnel quality, and parts of technical requirements, production program, technology and production management level of each are not identical, to control the quality of the parts or products to various special measures also vary, and heat treatment has the characteristics of continuous production operation, therefore, to seek a method of quality control in production process, to satisfy and improve the quality of heat treated parts especially the purpose of mass production parts quality is especially important. 1. The main content of the production process quality control method 1. 1 shift quality assurance mode of thinking and ideas in the past, we in the quality of heat treated parts quality assurance model and stay in the traditional quality management focus on thinking and ideas on pure final inspection, only pay attention to the quality of the results, not put the priority on the quality of forming, the control of the heat treatment defect elimination in the process of quality formation, once appear constantly parts defects or leak, cause a certain loss of quality. All kinds of personnel busy in part the result of treatment, the result is more busy more disorderly, repeatability and low-level errors occur frequently, abnormal passive work. We from these mistakes and meditation to summarize and draw lessons from failure and find and explore the method of success, the key work of quality management for the recognition and positioning. By studying relevant content and heat treatment of heat treatment standard management success experience, has been clear about the improve the quality of heat treatment must first change of all kinds of personnel of quality assurance mode of thinking and ideas, is the traditional pure by passive control, final inspection to prevention, combining prevention and inspection of the active control of the quality assurance model, set up the clear responsibility, standardized management and strict rewards and punishment and the professional technology, management technology, the scientific method, centralized and unified and full participation, process control, comprehensive management 'three-pronged' process quality control management ideas and concepts. A few years to implement the results show that the change of idea and concept is the comprehensive effective implementation of the core and key of process quality control. 1. 2 strengthening the management of 'four' ( 1) Implement and control factors of strengthening heat treatment standard gauge management as a special production process of heat treatment process, what are the elements of the control in the whole process of production, staff should do, how to do better specifications and code of conduct is to sincerely carry out and implement standard heat treatment. As a civilian goods production of military products and foreign trade companies, we first
