Alloy indefinite chill cast iron roll

Alloy indefinite chilled rolls is a cast iron roll with fine intercrystalline graphite evenly distributed throughout the working layer of rollbarrel. The sizes,shapes and distributions of graphite and carbide are controlled by the chilling effect and the contents of alloy elements. The addition of alloy elements such as Manganese,Nickel,Chromium,and Molybdenum changes the matrix microstructure from pearlite, bainite to martensite. The existence of small amount of fine graphite enhances the roll's resistance to spalling, thermal crack and wearability. This roll has small hardness gradient in the working layer of roll barrel and is suitable to medium and finishing stands for bar,wire and profiling mills.
