在分析轴承钢高温奥氏体再结晶规律的基础上，提出了抑制网状碳化物的控温轧制工艺，即大断面轴承钢采用900 ℃终轧，轧后以大于3 ℃/s的冷速冷却到700~550 ℃。利用有限元技术，模拟分析了工艺的可行性。现场实验结果表明，网状碳化物级别合格率大幅提升到77.3%，效果显著。

Based on the recrystallization laws of deformed austenite of bearing steel, a controlled rolling technology to inhibit net carbide was proposed with finishing rolling temperature at 900 ℃, cooling rate after rolling higher than 3 ℃/s and reheating temperature in the range of 700~550 ℃.The feasibility of this controlled rolling technology was studied by FEM simulation. The result of field test shows that the largecrosssection parts produced with new technology have excellent performance and qualification rate in terms of net grade was increased to 77.3%.
