铸造复合轧辊的几种新方法

高速钢用作轧辊材料使冷、热带钢工作辊寿命得到大幅度提高，但是用常规生产方法包括离心铸造法很难生产出高速钢复合轧辊。介绍了几种新的复合轧辊的生产方法，成功地生产出外层与心轴良好结合的高速钢复合轧辊，其中一些方法可方便地复合各种材料

Several New Ways for Casting Compound Rolls

The high speed steel as a roll material significantly increased the service life of hot and cold strip mill work rolls.But it is very difficult to produce the HSS compound rolls by conventional methods including centrifugal casting.Several new ways for making HSS compound rolls are introduced.By those methods HSS compound rolls are manufactured with good bonding at the interface of the core cladding alloys.Of the methods the materials with very different chemical composition can be conveniently cladded on the core alloy.
