Research, transformation and upgrading of vacuum sintering furnace
Vacuum sintering furnace is a new type of heat treatment technology combining vacuum technology and heat treatment technology. The vacuum environment of vacuum heat treatment refers to the atmosphere environment lower than one atmospheric pressure, including low vacuum, medium vacuum, high vacuum and ultra-high vacuum. Vacuum heat treatment actually belongs to atmosphere controlled heat treatment. Vacuum heat treatment means that all and part of the heat treatment process are carried out in vacuum state. Vacuum heat treatment can realize almost all the heat treatment processes that can be involved in conventional heat treatment, but the quality of heat treatment is greatly improved. Compared with the conventional heat treatment, the vacuum heat treatment can achieve no oxidation, no decarburization, no carburization, can remove the phosphorus chips on the surface of the workpiece, and has the function of degreasing and degassing, so as to achieve the effect of surface bright purification.
With the development of science and technology in China and the promotion of its influence in the world, domestic manufacturers have begun to trial produce high-end products, and the market demand for vacuum sintering furnace is increasingly urgent. Now according to the market demand, combined with the similar equipment abroad, we have developed a new generation of sintering equipment - high temperature vacuum sintering furnace. High temperature vacuum sintering furnace takes molybdenum wire as heating element, adopts double shell structure and pid30 program temperature control system, phase-shifting trigger and silicon controlled control. The furnace adopts soft and hard carbon fiber materials, which can quickly rise and fall the temperature. High temperature can reach 1700 ℃. It is an ideal product for vacuum sintering in universities, scientific research institutes and industrial and mining enterprises.
At present, with the development of electronic information technology and the prosperity of economy in China, laboratory materials tend to be more and more high-grade, small batch, multi variety and so on. The former vacuum sintering furnace has gradually failed to meet the high-grade products and changeable requirements. High temperature vacuum sintering furnace emerged as the times require and has been ordered by many colleges and universities.
