At present the spray cooling method is used to the high carbon chrome bearing steel in the forging process. The traditional manual method of spray cooling controlling easily cause the slow cooling speed and uneven. Especially above 850 degrees Celsius, it is possible to produce reticular carbide which affects the bearing service life. According to the shortage of the existing technology, the paper design a kind of bearing forging controlled cooling device which can accurately control the spray cooling mainly consisted of delivery area, spray area, soak area and measuring temperature area. This device can complete spray cooling, soaking, measuring temperature, and other functions, effectively solves bearing forging spray cooling accurate controlling problem.

Martensitic high carbon high strength SAE 52100 bearing steel is one of the main alloys used for rolling contact applications where high wear resistance are required. Due to its high fatigue strength, SAE 52100 is recently being used not only for the production of bearings but also shafts. Refining of prior austenite grain through repeated quenching is a procedure that can be used to enhance the material’s strength. In this work, the microstructure of repeatedly quenched SAE 52100 steel and its fatigue strength under rotating bending were investigated. It was found that repeated furnace heating and quenching effectively refined the martensitic structure and increased the retained austenite content. Repeated quenching was found to improve the fatigue strength of SAE 52100.
