Heat treatment equipment manufacturing has a turn
During the "Ninth Five-Year Plan" period, due to the financial constraints of state-owned enterprises, the climax of heat treatment equipment has not yet arisen. Moreover, due to the entry of foreign-funded enterprises, the competition in the domestic heat treatment equipment market has become fierce, which has left many technologies behind, and enterprises with poor management are on the verge of bankruptcy. Since the "10th Five-Year Plan", the emergence of a large number of private enterprises has greatly increased the demand for equipment. Even low-level equipment has been sold well and saved a group of electric furnace manufacturers. The entry of foreign-funded enterprises and the high-tech starting point of users have also enabled many equipment manufacturers to make great efforts to improve their product grades and win users. It is worth mentioning that many equipment manufacturing enterprises should adopt high-quality matching parts and instruments according to user requirements. Among them, there are many international famous brand products, which have significantly improved the reliability of domestically produced equipment, and created a good technological transformation and equipment renewal for heat treatment processing enterprises. condition.
(3) Progress in heat treatment standardization
Before the implementation of the reform and opening up policy, the basis of heat treatment standards was very weak. Before 1980, there were only 12 metallurgical quality standards for steel in the national standard and YB. There were only 8 heat treatment standards in the machine standard (JB), and most of them were product quality inspection standards. Since the reform and opening up, especially after the introduction of the equivalent adoption of the international standard policy, standard work including heat treatment standards has seen a new situation. Standardization agencies in all government departments have special personnel responsible for heat treatment standardization. The plan for the revision of 94 national and ministerial standards is listed in the proposed heat treatment standard system table. A total of 21 standard revision tasks were completed during 1981-1985. In order to standardize the work of cross-sectoral and cross-regional industry management, and to mobilize more extensive forces to achieve standard modernization as soon as possible, the National Bureau of Standards (now the National Technical Supervision Quality Inspection and Quarantine Bureau) decided in 1985 to establish the nationality of various industries. Standardization Technical Committee. In March 1986, under the auspices of the National Standards Bureau, the first cross-industry cross-sector heat treatment standardization technical committee consisting of 30 members and consultants was established. The Secretariat is located at the Beijing Institute of Mechanical and Electrical Engineering, Ministry of Machinery Industry. In 1991, the second committee was re-elected. In 1997 and 2001, he was reelected as the 3rd and 4th committees. The main tasks of the committee are: to propose the policy recommendations for the standardization work of the industry to the competent national authorities, formulate the industry standard system table, propose long-term planning and annual work plan, organize the revision and revision of the industry standard projects, and review the national standard of the industry. And the draft of the standard, and technically check, responsible for the standard implementation, interpretation, consultation, award recommendations for standard results.
After nearly 20 years of hard work, 76 national standards and standards have been revised. Most of the contents are general technical standards and process standards for heat treatment, excluding product quality standards. Most of them are national standard heat treatment general technical standards. In the domestic and international trade negotiations, the organization and properties of metal materials after heat treatment have a function. Recognized quality and quality criteria, product quality inspection methods also have a common yardstick. The newly developed heat treatment process standard can be used to strictly control the production conditions (equipment accuracy, reliability and maintenance, temperature, furnace gas, heating and cooling medium, etc.), which is an effective measure to achieve total quality management of heat treatment production.
In recent years, the acceptance inspection activities organized by the National Thermal Standards Committee for heat treatment have improved the enthusiasm of enterprises to implement heat treatment standards, improved the production management and quality management of enterprises, and improved the reputation, efficiency and core competition of enterprises. ability.
