铸造冷硬矫直辊的国产化研制

将国内原有的生产冷硬矫直辊厂家采取铸直车曲方法，与本方案将冷型设计成垂直分型面，轴向对开的铸造方式进行对比。对矫直工作原理，碳、硅、铬、磷化学元素进行了简单的分析，选择了成本较低的低铬合金冷硬铸铁材质，介绍了对试样白口层的检验和判断方法。

Localization Development of Casting Chilled Cast Iron Straightening Roller

The method that casting straight cylindrically and turning the surface taken by domestic original manufacturers of cold straightening roller was compared with the case that chilled model with vertical part- ing plane was designed and axial dimidiate cast. It conducted a simple analysis on straightening theory and chemical elements , such as carbon, silicon, chromium, phosphorus, selected low--cost low--chromium alloy chilled cast iron, introduced inspection and judgment of the white layer of the sample.
