卷板机位于热连轧机尾部,在整个轧线上起着重要作用,直接影响轧材的产量和质量。我厂原制造的1700mm热连轧机卷板机,由于历史的原因,在设计、制造、安装等方面都遗留一些问题,造成开工以来一直不能正常生产,事故不断发生,成为整个轧线中的最薄弱环节。为了对这两台卷板机进行改造,本文就有关问题作如下探讨。原卷板机由张力辊、成形辊、卷筒、机架和移出机构五个部份组成(图1)。张力辊由一台250kW电机经过一台速比为2.25的减速器和万向接轴传动。成形辊有3个,分别布置
Bending machine is located in the hot rolling mill tail, plays an important role in the entire rolling line, a direct impact on the output and quality of rolled material. Due to historical reasons, some problems left in the design, manufacture and installation still left some problems for the 1700mm hot rolling mill coiling machine originally manufactured by our factory. As a result, the normal rolling mill production has not been able to be carried out since the start of construction. weakness. In order to transform these two bending machines, this article discusses the related issues as follows. The original coiler from the tension roller, forming roller, reel, rack and remove the mechanism of five parts (Figure 1). The tension roller is driven by a 250kW motor via a reduction gear unit with a speed ratio of 2.25 and a universal joint shaft. There are 3 forming rollers, arranged separately
