1422热轧精轧压下装置的改造

Screw-down System Revamp for Finish Mill 1422mm Hot Strip Mill

某热轧精轧机装备早期的纯电动压下机构,在线调整能力低响应慢,压下位置的检测方式也存在很多问题,无法满足产品厚度精度的要求。针对其存在问题进行了分析并提出了解决方案,使其压下机构的调整精度和效果达到了预期的目标。

One finishing mill of hot strip mill installed the early stage electric screw-down device,which has low capability for online adjustment and slow response,and also many problems for measuring methods to screwdown position,thus the precision of products thickness could not be fulfilled. This paper has made analysis on the existed problems and proposed a solution in order to enable the accuracy and result of screw-down adjustment achieve the expected target.
