摘　　要：通过提高出炉温度,对炉内和包内液面采取保护措施,采取倾斜浇注的方式等,消除了高铬铸铁衬板表面氧化夹渣缺陷。说明出炉温度、浇注温度及浇注方式是影响衬板表面质量的主要因素,控制好主要因素,也可以采用湿型砂生产高铬铸铁衬板,使生产成本大大降低。The oxid slag on the line surface was eliminated by increasing tapping temperature, protecting iron melt surface which in the ladle and furnace, and tilting pouring. The results show that, tapping temperature, pouring temperature and pouring manner are major factor which influence surface quality of line. If major factor is controlled accurately, the high chromium cast iron line can be produced with green sand process, the production cost can be reduced greatly.
