Basic Guide to Roll Bending And Plate Roll Capacity ,

Steel plate rolling consists of three steps pre-bending pressing head , centring and rolll bending 1 Pre-bending It can be seen from Figure 1 that only the part of the steel plate in contact with the upper roller shaft can be bent Therefore, there is a length at both ends of the steel plate, which can not be bent...

The Hot Rolling Process

The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process...
