Embodiment 1
[0033] Ingredients: Weigh raw materials according to the composition and mass percentage of the above alloy steel, including Cd: 0.06%, Mn: 1%, C: 0.6%, Tl: 0.1%, Cu: 0.03%, Co: 0.05%, and the balance is Fe and impurities, wherein impurities include P<0.04%, S<0.04%, N<0.04%, O<0.03%. The raw materials are melted to form alloy liquid and poured into the mold to form bearing semi-finished products.
[0034] Heat treatment: Temper the bearing semi-finished product first, heat it to 550°C, keep it warm for 10 minutes, cool it down to room temperature naturally, and then perform annealing treatment, heat the semi-finished product to 350°C, keep it warm for 5 minutes, cool it with the furnace, and then perform the second isothermal tempering treatment , keep warm for 3 minutes, cool to room temperature with external air, and finally anneal for the second time at a lower temperature, heat to 250°C, keep warm for 3 minutes and then cool naturally to room temperature.
