[0002] Quenching technology as a most common metal heat treatment process, usually is first heated to a certain appropriate temperature to the metal material, austenitizing, then rapidly cooling.

[0003] Nickel base non -magnetic bearing alloy is a kind of alloy material with high hardness, high strength, high toughness and good wear resistance. The alloy has very low magnetic permeability and excellent non -magnetic performance.

Subsequently, water quenching is carried out. The existing heat treatment mode mainly adopts pit furnace to carry out solid solution treatment on nickel base non -magnetic bearing alloy, and then is lifted out of the pit furnace into the water pool through the crane for water quenching. In this operation process, the time from lifting out of the furnace to entering the water pool is long, usually more than 1 minute, which leads to long exposure time of the material in the air, reduces the water temperature, and makes the solid solution treatment effect of the material insufficient, thereby affecting the mechanical properties after subsequent aging treatment, makes the hardness of the alloy high, and cannot achieve the expected effect of material performance. Therefore, it is necessary to optimize the heat treatment equipment. UTILITY MODEL CONTENT
