Chilled Cast Iron Rolls have a structure consisting of more flake graphite with few uniform carbides in a Pearlitic matrix. Harder grades have a Bainitic-Martensitic matrix with an increased amount of carbides. The presence of flake graphite improves spilling resistance and also enhances resistance to fire cracking. All of these properties ...

At Blaw Knox foundry, Mill rolls were cast with chills. steel segments the size of large bricks burried just under the sand, that soaked heat form the skin of the rolls. These were cast iron rolls, not tool steel. The result of cooling the skin fairly rapidly is a modified grain structure, (moving towards white iron) that is quite a bit harder.
