roll material

基本解释

The high speed steel (HSS) as a roll material significantly increased the service life of hot and cold strip milling work rolls.
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。
A rotating disk made of the roll material makes contact under load with stationary mild steel. The disk is heated by friction and cooled rapidly by a water jet spray.
用辊子材料制成的圆盘，在一定载荷下，旋转并和轧材制接触，由于摩擦产生的热量使圆盘被加热再迅速喷雾使圆盘快速冷却。

The roll material of the hot rolled stainless steel strip is the one of important factors, which will determine the surface quality, shape, efficiency and cost of production.
不锈热轧带钢精轧机组工作辊材质问题是决定产品表面质量、板形、生产效率和成本的重要因素。

It would be folly to try to roll back energy prics or raw-material prices by contriving recession or encouraging a maintained level of unemployment above 5.5 per cent.
