Alloy chilled cast iron roll series

Read：5090 2014-7-17

There is no free graphite basically in the matrix of work layer of alloy chilled cast iron roll,so its hardness is high with fine wear-esistant property.It can be used in small bar and wire rod as well as narrow strip steel fine rolling machine stand,and etallographinc structure contains fine pearlite andcarbide.
