| 摘 要： | 盘条中的夹杂、折叠、划伤和晶粒度不均等是造成冷镦钢冷镦开裂的原因。在炼钢时控制钢水的洁净度,连铸时防止钢水卷渣,控制速度为2.4~2.8 m/m in,轧钢时采用闭环温度控制、RSM轧制、STELMOR控冷技术。成品尺寸精度达到±0.1 mm,冷镦开裂得到了有效控制。

| Abstract: | Inclusion,lapping,stamp and uneven grain size are the main cause for crack during cold heading of cold heading steel wire rod.The measures are adopted: controlling the cleanness of molten steel during steelmaking,preventing to roll into residue during continuous casting and controlling the speed of 2.4～2.8m/min,adopting closed loop temperature control,RSM rolling,STELMOR control cooling technique during steel rolling.Dimension precision of finished products is up to ±0.1mm and crazing during cold heading is controlled in effect. |
