本文以历史的发展与现实情况为依据,着重评述初轧、型钢、板带、线材、钢管的轧制速度的发展必然趋势是高速化。同时由于速度的提高带来了一系列的问题(理论上、工艺上),对这些问题进行了一些粗浅的探讨与分析,以期引起广大轧钢工作者的重视,看到我们当今的差距而加强理论与实践的研究,为早日实现轧钢工业的现代化而奋斗。 Based on the historical development and reality, this paper focuses on the rapid development of the rolling speed of the first rolling, steel, strip, wire, steel pipe. At the same time, a series of problems (theoretically, technically) have been brought about due to the increase of speed, and some superficial discussions and analyzes have been made on these issues in order to arouse the attention of the general steel-rolling workers and to see our current differences and strengthen the theory And practice of research, strive for the modernization of the rolling industry as soon as possible.
