日本川畸钢铁公司发明的平辊轧制方坯的新方法正在该公司的水岛厂使用,使用革新的工艺使该厂可以用平辊轧制方坯(成品为方棒钢和粗圆棒)而不需要常用的孔型。用孔型轧辊来轧制半成品或大钢坯,它有许多不利的因素,其中如改变方坯尺寸就需要使用不同孔型轧辊,每种尺寸的方坯都需要换辊和调整,并且在停机时间大量影响生产,同时孔型轧辊也受到很大磨损。川崎钢铁公司新轧制方法解决了基于平辊使用所存在的问题。过去在连续轧制过程中,平辊从来没有被结合使用过。与孔型轧辊不同,方坯轧辊没有槽壁来约束,在轧制对方坯有变成平行四边形的趋
The new method of flat-rolled billet invented by KAWAKI Steel is being used at the company’s Mizushima Plant and the innovative process has enabled the plant to be used for flat rolling of billets ) Without the need for commonly used pass. There are many disadvantages to rolling semi-finished products or large billet with pass rolls, among which different pass rolls are required to change the billet size, roll changing and adjustment are required for billet of each size, and during downtime A lot of impact on production, while the hole roll also suffered a lot of wear and tear. Kawasaki Steel’s new rolling method addresses the problems that exist with flat roll applications. In the past in the continuous rolling process, the flat roll has never been used in combination. Different from the pass roll, the billet roll has no groove wall to constrain the rolling of the billet into a parallelogram
