Oil quenching heat treatment：The oil quenching and heat-treating parts are made of intelligent controllable atmosphere mesh belt/stick-type quenching and tempering automatic production line. It is suitable for martensite quenching of large-volume small and medium-sized bearing rings. The atmosphere in the quenching furnace is controlled by computer to realize the surface. Zero decarburization, high production efficiency, good product quality, easy to achieve different levels of heat treatment requirements by adjusting heat treatment parameters.
