ADAMITE ROLLS
Adamite Rolls are basically alloy steel rolls (a kind of high carbon steel) having hardness ranging from 40 degrees shore c to 55 degrees shore c with carbon percentage ranging from 1.35% to 2%. These rolls are primarily supplied for initial stands, where wear resistance is important along with considerable strength and toughness.
Because of certain special heat treatment technology, its high wear ability, good toughness and excellent resistance to fire crack, makes it ideal rolls for roughing stands.
