The Hot Rolling Process - California Steel Industries
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. The Hot Mill rolls slabs weighing up to 30 tons between 30” and 74 ...
HOT STRIP MILLS Mechanical Equipment - SMS group
SMS DEMAG Hot Strip Mills 10 The drum-type shear installed between the roughing and finishing mills of a hot strip mill crops the trans-fer bar at its head and tail. In special applications, the drum-type shear also serves to divide transfer bars and finished plates. Based on the experience gained from more than 60 drum-type shears built so far,
