近年来随着对轧件质量要求的提高及小型断面钢材采用围盘机械化工作的开展,出现了一种新的导卫装置的形式,即以滚动接触的导卫装置代替旧的滑动摩擦接触式的导卫装置。据英国“Journal of the iron and steel institute”(钢铁学会会志)1954年4月号报导,在瑞典由于采用滚动式导卫装置的结果,在线材轧机上成功的解决了轧制5公厘盘圆使用围盘和反围盘装置的问题。轧
In recent years, with the improvement of the rolling quality requirements and the mechanization of the small cross-section steel plate with the deployment of mechanization, there has emerged a new form of guide device that is rolling contact with the guide to replace the old sliding contact friction device The guide guard. According to the April 1954 report by the Journal of the Iron and Steel Institute in the United Kingdom, the rolling mill was successfully rolled out on a wire rod mill in Sweden as a result of the rolling guide, Round the use of dashboard and anti-disk device problems.
