研究采用不同的控轧控冷工艺对高碳铬轴承钢网状碳化物析出的影响。结果表明，轧制过程中采用控制冷却工艺，将终轧温度控制在两相区某一温度区间内，一定程度上改善轴承钢碳化物网状。而采用控制冷却与轧后快冷相结合，碳化物网状有明显改善。特别是当加大轧后冷却强度，将钢材返红温度控制在较低温度时，能够得到分散细小的碳化物，碳化物网状级别更好。

The influences of different controlled rolling and controlled cooling technology on network carbide pre?cipitation in high-carbon chromium bearing steel were studied. The experimental results indicated that adopting con?trolled cooling technology to control finishing rolling temperature at a temperature within two phase zone during rolling process, the carbide network of bearing steel was improved to a certain extent. If connecting controlled cooling technolo?gy with rapid cooling technology after rolling, the carbide network of bearing steel was improved obviously. Especially increasing cooling intensity after rolling and controlling a lower self-tempering temperature, dispersed fine carbides were obtained, and the carbide network was better.
