Forged Rolls Forging is a process in which the cast ingot is heated in the furnace & then material is hammered according to the customer's required specifications. Thereafter heat treatment is done in annealing furnace.
HSS rolls, often installed in the earlier stands of hot strip mills, provide improved wear resistance along with a better surface roughing resistance. However, HSS are rolls more sensitive during operation and require a higher grade of attention with regard to roll cooling than High-Cr rolls. HSS rolls need an adequate mill operating environment
Tungsten carbide rollers can be divided into solid carbide rolls and composite hard alloy rolls according to the structure. Solid carbide rolls have been widely used in pre-finishing and finishing stands for high-speed wire rod mills (including fixed reduction racks, pinch roll stands).
on wear is another issue. Stresses from Hertzian pressure in 4-high cold mill back up rolls were measured years ago, the results were never published, but of high interest - also, maybe later. K. H.
