随着现代冶金工业的高速发展和轧钢生产日益增长的需要,许多新型轧辊材料正在不断地涌现出来,高NiCr合金铸铁就是其中一种。这种轧辊材料中含有较多的NiCr合金元素,因此由它制成的轧辊具有优良的性能,受到了广大用户的欢迎。但是,这种材质的轧辊切削性能却很差,因此成为一种很难切削的轧辊。大家知道,在新轧辊生产和旧轧辊切 With the rapid development of modern metallurgical industry and the growing demand for rolling production, many new roll materials are emerging. High NiCr alloy cast iron is one of them. This roll material contains more NiCr alloy elements, the roll made from it has excellent performance, by the majority of users. However, this kind of material has a poor machinability, making it a hard-to-cut roll. We all know that in the new roll production and the old roll cut
