在轧钢生产过程中,换辊是很重要而且也是不可避免的工作,尤其是在生产品种较多的车间,换辊时间的长短和工作质量的好坏直接影响到整个轧钢车间产、质量任务的完成。过去各轧钢厂只单纯的注意到如何在生产时间上去提高产量,而对如何缩短非生产的辅助时间则重视不够。鞍山钢铁公司各轧钢厂在缩短换辊时间与提高换辊工作质量等方面作了很多努力与改进,并且取得了很大的成绩,该公司中型厂的换辊时间从过去的5—6小时缩短到1点45分钟;小型厂的换辊时间从过去的4.5—5小时缩短到2点29分钟(包括围盤装置的安装
In the steel rolling process, the roll change is very important and inevitable work, especially in the production of more varieties of workshops, the length of the roll change and the quality of work directly affects the entire rolling plant production and quality tasks carry out. In the past, the rolling mills only simply noticed how to increase their production time, but did not pay enough attention to how to shorten the non-production auxiliary time. Anshan Iron and Steel Company’s rolling mill in the reduction of roll change time and improve the quality of the work roll has made a lot of efforts and improvements, and achieved great success, the company’s mid-sized plant roll change time from the previous 5-6 hours shortened To 1.45 minutes; the roll-off time of the small factory was reduced from 4.5-5 hours in the past to 2.29 minutes (including the installation of the enclosure device
