在棒材轧制中,轧制故障频繁,对出现的故障不能准确地确定其原因,并及时处理是造成轧机作业率低的主要原因。棒材轧机的作业率比炼钢、连铸的作业率低得多,从而导致连铸坯直接热装或连铸连轧在生产节奏上不能衔接。因此降低轧制故障、提高轧机的作业率、不仅对提高轧机质量、产量有利,而且是连铸坯热装和连铸连轧不可缺少的技术。 Rolling in the bar, frequent rolling failure, the failure can not accurately determine the cause of the problem, and timely processing is the main cause of the mill operating rate is low. The operating rate of bar mills is much lower than that of steel-making and continuous casting, which leads to the continuous rinking of continuous casting slabs or continuous casting and rolling. Therefore, to reduce the rolling failure and improve the operating rate of the rolling mill is not only an indispensable technology for improving the quality and output of the rolling mill, but also for hot charging and continuous casting and rolling of continuous casting slabs.
