A connecting pipeline is arranged between the multi-foldtype turbulent flow heat exchange assembly and the vacuum sintering furnace body. A Z-shaped pipeline is arranged between the multi-fold type turbulent flow heat exchange assembly and the centrifugaldraught fan. The characteristics that the structure is simple, the cooling speed is high, energy saving and environment friendliness are achieved, and dismounting and mounting are convenient are achieved. The problem that the production efficiency cannot meet the requirement is solved.

Description

technical field [0001] The invention relates to the technical field of sintering cooling equipment for samarium-cobalt magnets, in particular to a vacuum cooling system of a samarium-cobalt vacuum sintering furnace. Background technique [0002] The vacuum sintering furnace is a complete set of equipment that uses the principle of resistance heating to sinter various metal powder compacts under vacuum or protective atmosphere conditions, and the best material properties can only be obtained through rapid cooling during the cooling process. It is mainly suitable for sintering and heat treatment of cemented carbide, powder metallurgy, and magnetic materials. As for sintered samarium cobalt materials in the field of magnetic materials, in order to obtain relatively excellent comprehensive performance, not only a high degree of vacuum and consistency of furnace temperature are required in the sintering process to ensure the consistency of product performance, but the cooling of ...
