What are the commonly used cast iron rolls?
In China's current standards, cast iron rolls are divided into chilled cast iron rolls, infinite chilled cast iron rolls, ductile iron rolls and high chromium cast iron rolls four categories. Because of the composition, inoculation, cooling rate, heat treatment, etc., cast iron has formed a huge system. Various cast iron rolls have different arrangement structures and functions and can be used in different rolling mills.
