We provide highly efficient Adamite Rolls in the market. Adamite is a material, mechanical properties and carbon content of which stands between steel and iron. Owing to its alloy elements such as NiCrMo etc. there are some amount of carbide in the matrix and because of certain special heat treatment technology, high wearability, good toughness and excellent resistance to fire crack are obtained. The advantage of Adamite Rolls is that almost no hardness gradient in the working layer is required.
