[0002] Bearing steel grit is made of scrap steel, which is wear-resistant and non-fragile, and has a hardness similar to that of bearing steel. Bearing steel grit can be used as an abrasive to polish various metal surfaces and improve the finish of the metal surface. When processing bearing steel grit, it needs to be quenched. However, when quenching steel grit in a quenching furnace, it is necessary to manually use a shovel to move the steel grit into the quenching liquid little by little, resulting in the steel grit not being able to enter the quenching liquid in time, thereby affecting the quenching effect of the steel grit. Therefore, it is urgent to design a quenching furnace for bearing steel grit production to solve the above problems. Utility Model Content
