Adamite rolls have a carbon content of 1.5% to 2.3% with various alloy elements such as Cr, Ni, Mo, and V. Generally, the mass fraction of free carbides is about 6% to 10%, with small hardness drop and high wear resistance. The rolls have high performance, good toughness, significantly reduced consumption, improved surface quality of profiles and rail beams, etc. They are widely used to replace cast steel rolls and low-alloy cast iron rolls, such as large-sized steel rough rolls, profile steel rolling mills, intermediate rolling mills, work rolls in the hot rolling strip continuous mill, etc.
