链轮用45钢热轧钢带的试制

Trial Production of Hot Rolled Strip of 45 Steel for Sprocket

总结了链轮用45钢热轧钢带的试制过程。根据化学成分特点和加工性能要求,制定了某轧线45钢钢带的加热制度、轧制温度和层流冷却等控轧控冷工艺。按照制定工艺生产的45钢钢带,满足链轮的加工制造要求。另外,通过降低卷取温度,解决了在链轮生产时的"粘刀"问题,进一步提高了链轮用45钢热轧钢带的产品质量。

The trial production of hot rolled strip of 45 steel for sprocket was summarized.According to the chemical composition characteristics and processing performance requirements,the heating system,rolling temperature and laminar cooling for control rolling and control cooling of 45 steel strip in a rolling line were formulated.The 45 steel strip produced according to the formulated process fulfilled the manufacturing requirements of sprocket.In addition,by reducing the coiling temperature,the problem of"sticking knife"in sprocket production had been solved,and the quality of hot rolled strip of 45 steel for sprocket was further improved.
