摘要
结合线材生产线设备布置情况,制订了Φ5.3mm盘条高精度轧制方案,通过严格控制轧线温度,成品孔型重新设计,精确计算减定径机组轧件尺寸与速度,在计算机控制系统采用Φ5.0mm盘条轧制程序表的基础上,开发出了椭圆度不超过0.20mm的Φ5.3mm高精度盘条,尺寸精度达到Φ5.3mm±0.1mm。
The paper drew up the plan of high precision roiling of φ5.3 mm wire rod combined with production line equipment arrangement of wire rod. On the basis of φ5.0mm wire rod rolling schedule by computer control system, through controlling the rolling temperature strictly, designing the finished roll pass again, calculating rolled products dimensions and rolling speed of RSM exactly, produced the ovality of no more than 0.20mm high precision wire rod of φ5.3mm, the size precision reached 05.3mm±0.1mm.
