一、前言在实际生产中,为了提高连铸机产量,并保证操作稳定,连铸方面希望用单一规格的结晶器,大量连续浇注同一成份的钢水。但为了满足用户的要求,轧钢方面却希望能按多品种小批量进行生产。这种相互间的矛盾,给连铸与轧钢的同步生产带来很大困难,为了解决这一矛盾,川崎公司水岛厂结合该厂的具体条件,针对多品种换辊时间长的问题,开发了布置非常紧凑的新型的VH4机架钢坯连轧机,利用机架搭载台车,实现了四 First, the preface In actual production, in order to improve the continuous casting machine output, and ensure the operation is stable, continuous casting hope that the use of a single mold specifications, a large number of continuous pouring of the same composition of molten steel. However, in order to meet the requirements of users, the rolling mill hopes to produce more products in smaller batches. This contradiction between each other to the continuous casting and rolling the production of great difficulties, in order to solve this conflict, Kawasaki company Mizushima plant with the specific conditions of the plant, for a variety of long roll change problems, the development A very compact layout of the new VH4 stand billet rolling mill, the use of rack-mounted trolley, to achieve a four
