Alloyed steel roll


The alloy content is greater than 0.8%, with a carbon content of 0.4-1.3. Cr, Ni, Mo, and V are added, and the matrix structure undergoes normalizing and tempering heat treatment to become sorbitol and pyrocatechol. This type of rolling mill has good strength and is usually used for initial rolling and slab rolling mills, rail rolling mill roughing stands, profile and bar roughing stands, etc.
