The carbon content of the alloy adamite roll is usually between 1.2-2.3%, the rest contain Cr, Ni, Mo and other alloy elements.
Through a special heat treatment process, compared with alloy cast steel roll it has a good abrasion resistance; as well as compared with cast iron roll it has a good strength and toughness.
The prominent feature of semi-steel adamite roll is the small variation in hardness of shell, and has a good abrasion resistance and bite performance, in addition, the semi-steel adamite roll is cast as a whole, there is no weak interface in compound casting roll, and thus it has a better anti-accident capacity.
Standard includes ISO, GB, ASTM, DIN, JIS.

2.0 Application
