Technical Field

The invention relates to the technical field of samarium cobalt magnet sintering cooling equipment, in particular to a vacuum cooling system of a samarium cobalt vacuum sintering furnace.

Background

The vacuum sintering furnace is a complete set of equipment which enables various metal powder pressed bodies to be sintered by utilizing the principle of resistance heating under the condition of vacuum or protective atmosphere, and can obtain the best material performance after being rapidly cooled in the cooling processing process. It is mainly suitable for sintering and heat treatment of hard alloy, powder metallurgy and magnetic material. As a sintered samarium cobalt material in the field of magnetic materials, in order to obtain relatively excellent comprehensive performance, the high consistency of vacuum degree and furnace temperature is required in the sintering process to ensure the consistency of product performance, and the cooling rate of a vacuum sintering furnace is also an important part of the samarium cobalt magnet capable of obtaining high comprehensive performance. However, after the sintering of the traditional vacuum sintering furnace is finished, the product is discharged from the furnace after reaching the normal temperature through natural cooling. Because the internal temperature of the vacuum sintering furnace is higher during working, the internal temperature is naturally cooled to below the specified temperature or even normal temperature, and the required time is longer; meanwhile, in order to ensure the quality of products, the furnace door cannot be opened during cooling, so that the vacuum sintering furnace is cooled very slowly, and the production efficiency is further influenced.
