Abstract
PURPOSE: To enhance the seizing and wear resistances of the title material by making the material of high carbon high chromium cast iron having a specified compsn. Si and Mn.
CONSTITUTION: This hot rolling mill roll material consists of, by weight, C 3.5W 4.5%, Si 0.3W2.5%, Mn 0.3W2%, Cr 10W25%, and the balance Fe and impurities or further contains one or more out of Mo≤10%, W≤10% and V≤5% as required. Ni≤5% may be added furthermore. Since this material is of high carbon and high chromium, a large amt. of granular or lumpy special carbide is precipitated to perfectly prevent seizing, and the Mo, W, V and Ni raise the hardness of the carbide. This material well satisfies surface roughening resistance and heat crack resistance which are required as a hot rolling mill roll material as a matter of course.
