Adamite Rolls & ALLOY STEEL ROLLS

Equipped with one of the best adamite rolls brands, Makkah Export Group is one of competitive AD mill rolls manufacturers and suppliers in india, Adamite is a material, mechanical properties and carbon content of which stands between steel and iron. Owing to its alloy elements such as Ni、Cr、Mo,Mn,Si, etc, there are some amount of carbides in the matrix and because of certain special heat treatment technology, high wearability, good toughness and excellent resistance to fire crack is obtained.
The biggest advantage of these rolls is almost no hardness gradient in the working layer. These rolls are used in rough mills and front stands of the finish mill for hot strip mills, rough stands, intermediate stands and pre-finishing stands for bar and wire mills, roll rings and roll sleeves for universal mills and cantilever mills.
