Roll chocks in Rolling Mill – IspatGuru

Aug 08, 2019These heavy loads have, in the past, caused wear on the bearing surfaces of both work roll chocks and the mill housing. To minimize this wear, and to facilitate maintenance of the roll stands, it is the normal practice to provide wear plates, or liner plates, in the form of high-strength hardened steel plates on the face of the mill housing and

What are roller chain wear indicators?

Oct 23, 2018The best indicator of wear is chain elongation, which in reality indicates how much wear has occurred at the chain's pins and rollers. Roller chains eventually wear out to such an extent that they require replacement. A typical benchmark for this is at 1.5 to 2% (12.180 in./ft to 12.240 in./ft) elongation. Chains may work until they reach 3%
