Alloy Infinite Chilled Cast Iron Roll
 
 
 
There are fine graphite among crystallize in working layer of alloy infinite chilled cast iron roll. The size, form and distribution of graphite are able to be controlled through chilling action and alloy content. Due to addition of Mn, Cr, Ni and Mo, the matrix is able to be changed from pearlite and bainite into martensite. In addition to a little of fine graphite, the anti-strip, thermal cracking resistance and wearable performance are improved, the hardness difference in working layer is much lower, applicable to medium rolling and finishing rolling rack for rod, wire materials and profile steel.
