Hydraulic gap control system is the key part of accuracy for stripe gauge control of tandem cold rollingmill. Hydraulic screw down system is the most important part of hydraulic roll gap control.
The result shows that production of high strength screw bars is reasonable by the control rolling and control cooling process on high-speed wire mill with the capacity of low temperature rolling.
结果表明,在具有低温轧制能力的高线轧机生产线上,采用控轧控冷工艺生产高强度钢筋是可行的。
