Forged Steel Roll Back Up Roll For Rolling Mill TINVO

Definition. The forged steel work roll is solid-forged roll made of alloyed steel, close to eutectoid and hypereutectoid steel. It has a good combination with hardened surface which creates a strengthened Failure of ICDP rolls has been discussed in the present study. The F#5 stand bottom work roll was spalled in operation. Failure occurred after 448T of production in the last campaign. This failure resulted in 3.5 h of breakdown in the mill. This roll failed after use of 90 times during the campaign in the mill.Analysis of a Progressive Failure of a Work Roll in Hot Strip Mill

4-hi mill is the mainstream of HSM in the world (Fig. 1 a). Roll proﬁle In this work, the contact behaviours between work roll and backup roll of a hot strip mill were investigated.Compared to traditional 4-high and 6-high technology, the work-roll diameters of the X-HI mill insert are much smaller, which results in significantly reduced rolling forces and rolling torques. Especially for the production of hard and thin products, the small work-roll diameter permits large thickness reductions without costly intermediate Flex-HI: Put More Muscle into your Mill — Metals Magazine
