钢的热轧(迭轧薄板除外)历来都是用大量的冷却水喷向轧辊,进行冷却和润滑。这种传统的方式,至今仍为大量的热轧机所沿用。轧制过程工艺润滑的研究,与其它类型的润滑相比,一直没有引起重视,尤其是热轧工艺润滑的研究,更晚于冷轧。近年来,对热轧钢板、带钢及供冷轧用的热轧板卷的需要量不断增加,国外上述产量约占钢材总产量的60%或更高,用户对产
Hot rolling of steel (except for the lamination of thin sheets) has traditionally been carried out with a large amount of cooling water toward the rolls for cooling and lubrication. This traditional method is still used by a large number of hot rolling mills. Rolling process lubrication research, compared with other types of lubrication, has not attracted much attention, especially hot-rolled lubrication process, later than the cold-rolled. In recent years, the demand for hot-rolled steel sheet, strip and hot-rolled coils for cold rolling has been on the increase. The overseas production accounts for about 60% or more of the total output of steel products.
