The Hot Rolling Process - California Steel Industries

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.

60 YEARS OF ROLLING MILL TECHNOLOGY By Ford B.

2016-6-8  Hot and cold metalworking between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519. When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel
