摘　　要：通过优化高速线材控制冷却工艺,提高风冷强度,增大吐丝后冷却速率,有效防止了高碳钢晶粒快速长大网状碳化物的析出,提高了索氏体率,改善了盘条螺纹钢性能稳定性和晶粒度,提高了线材产品的质量。This paper describes the optimization process of controlled cooling in the high-speed wire rod rolling plant,and verifies the practicability and effectiveness of the controlled cooling process.The cooling technology control is optimized to improve the air cooling strength,increase the cooling rate after the laying head which can effectively prevent the precipitation of network carbides in the high carbon steel grain rapidly growing,increase the Sorbitic ratio,improve the performance stability and grain size of bars in coil and the wire rod products quality.
