一、热轧精轧机工作辊移动化改造近几年来,对热轧板的厚度、宽度、凸度、平直度等方面的质量要求越来越严格。加古川制铁所热轧厂为了满足上述要求,进行了以实现工作辊移动化为开端的精轧机改造工作,于1987年3月完成了这项工作,并开始运行。在此,对轧机改造的目的及其基本规格、改造工程的概况作一介绍。 1.改造内容这次进行了下述改造: (1)以改善钢板凸度和提高板形控制能力为目的的改造,其内容为在F_3机架中安装短移动行程装置、在F_4～F_7机架中安装长移
First, the hot rolling mill work roll transformation In recent years, the hot-rolled sheet thickness, width, convexity, flatness and other aspects of the quality requirements more stringent. In order to meet the above requirements, the Kakogawa Ironworks Hot Rolling Mill completed the work of finishing mill transformation starting with the shift of the work rolls and completed the operation in March 1987 and started its operation. Here, the purpose of rolling mill transformation and its basic specifications, the outline of the renovation project to make an introduction. 1. Retrofitting The following modifications were carried out this time: (1) Retrofitting for the purpose of improving the crown of the steel plate and improving the control ability of the plate shape, which is to install a short travel stroke device in the F_3 frame. In F_4 ~ F_7 Long-term installation of the rack
