大H型钢精轧导卫稳定性改造

Stability Transformation of Finish Rolling Guiding in Large H-beam Steel

莱钢大H型钢生产线精轧机组采用的导卫装配为横梁装配式,导卫装配便捷,备件通用性较好。这种装配模式也存在着精度难以保证的缺点,随着设备的不断老化,因导卫原因出现的堆钢事故频繁发生,因此对该生产线精轧导卫进行了稳定性改造。通过增加导卫平衡装置,极大地提高了生产的稳定性。

The guiding assembly in finishing mill of large H-beam steel production line of Laiwu Iron and Steel Group is assembled by the cross beam with convenient assembly of guiding and good commonality of spare parts. This assembly mode also has the disadvantage that the precision is difficult to guarantee. With aging equipment, piling-up of steel occurs frequently because of guiding, so the stability transformation of finish rolling guiding in production line is constructed. The stability of production is greatly improved by adding a balance device for guiding.
