摘　　要：介绍新型高韧性高铬铸铁衬板的化学成分、熔炼、复合变质处理、造型、热处理工艺以及装机运行试验。新型高韧性高铬铸铁衬板不含价格昂贵的钼、铜,采用了适合我国资源特点的高效稀土复合变质剂,价格低廉;热处理采用空气冷却,硬度达到60HRC以上,冲击韧度达到8J·cm-2以上,耐磨性为ZGMn13高锰钢衬板的2.6倍。The chemical composition,melting,compound inoculation,mouldin g ,heat treatment and running test of a new type of high toughness and high chro mium cast iron liner was described.This new type of liner is made using not exp ensive molybdenum and copper,but some kind of high effect and low-priced rar e earth compound inoculant.The liners were heat treated with air cooling,their hardness reached60HRC or higher,impact toughness reached8J·cm-2 or higher,wear resistance was as high as2.6times of that of ZGMn 13hig h manganess steel liners.
