Cold rolling mills are under pressure to produce more, higher-quality steel. Equipment needs to cope with demands of greater dimensional accuracy, improved surface quality, higher steel grades and output speed. All this while overcoming the daily challenges of high precision, high loads, high speeds and aggressive coolants.
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
