Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a loading and unloading transition device of a vacuum furnace for heat treatment. Background Art

[0002] Vacuum furnaces are used as one of the equipment for equipment renewal in the heat treatment industry. The important reason is that the surface of the parts processed by vacuum furnaces is bright, less oxidized, good in performance and high in precision. It is easy to achieve energy saving, consumption reduction and pollution reduction in the production and operation of vacuum furnaces. It is a clean production equipment that meets the requirements of today's environmental protection. There are very few gas molecules in a vacuum, and the free path of molecules becomes larger, so light rare metals, refractory metals, rare metals and other special alloy materials that cannot be obtained under normal pressure can be produced.

[0003] Compared with traditional metallurgy, vacuum metallurgy has the advantages of low energy consumption, high recovery rate, no pollution, good economic benefits, etc., so it is increasingly valued by people. However, the research on vacuum metallurgical process depends to a large extent on the development of vacuum smelting equipment. With the continuous development of vacuum metallurgical technology, vacuum smelting equipment needs to be continuously improved, the degree of automation needs to be improved, and vacuum smelting equipment needs to develop in the direction of intelligence and integration. Temperature is an important process parameter for metal smelting. In the process of metal smelting, the precise control of temperature often determines the quality of the product. With the development of electronics, computers and network technology, the automation control system has gone through the combined analog control system, centralized digital control system, distributed control system, and developed to the fieldbus control system and Ethernet system stage. The development of control system shows a direction of decentralization, networking and intelligence. Among them, the networking trend in production process automation, instrument monitoring and diagnosis is the most significant. Distributed control is the monitoring and control of remote equipment by local computers through network systems, including data acquisition, monitoring and maintenance of equipment. System distributed control is one of the key technologies for the safe and stable operation of large equipment, and it is also the basis for improving the working efficiency and reliability of electromechanical systems, and for predictive maintenance and predictive management.
