The chilled cast iron roller, covered densely with the half-moon grooves on its hardened surface for hot-rolling the mild steel checkered plate, is a typical hard-to-machining workpiece. 热轧花纹板的冷硬铸铁轧辊,是典型的难加工材料,表面密布半圆形槽腔。
Based on the analysis of technical keys, checkered plate was successfully developed on the CSP production line with distinguished economic profit. 通过对花纹板开发过程中技术要点的分析,成功地在CSP生产线上开发出了花纹板,取得了良好的经济效益。
