Adamite Rolls

adamite is a matex`rial , mechanical , chemical properties and carbon content of which stands between steel and iron along with its alloy elements such as ni, cr, mo etc.

adamite rolls are 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%.

adequate heat treatment is very much necessary to achieve requisite wear resistance along with strength and toughness

the roll contains carbides, and therefore the wear resistance is obviously improved comparing with hypo-eutectoid and eutectoid steel

an outstanding feature of adamite rolls in that the inner hardness is about the same as that of the surface. Adamite steel rolls are classified as ordinary

to obtain excellent comprehensive properties modification is conducted with special rare-earth or other powerful agent, then through a multi-stages heat-treatment process, that consists of briquette carbides dispersed in the matrix of palletized pearlites can be gained, which perform well on strength, toughness and hot crack resistance.  

these rolls are used in pre-finishing to polishing stands in structure mills where wear resistance is very important along with considerable amount of strength and toughness.
