ABSTRACT:
A mini hot strip mill comprises three close coupled mill stands including a first and second four high finishing mill and a two high roughing mill positioned therebetween. A first coiler furnace is positioned upstream and a second coiler furnace is positioned downstream of the mill. The mills may each be retained in their own mill housings or the finishing mills may be in separate housings and the roughing mill may be retained in supports connecting the finishing mill housings. The mills are closely spaced so that the finishing mills are maintained open while operating in a roughing mode so as to allow free passage of the slab being reduced and the roughing mill is maintained open while the two four high mills are operative in a finishing mode. Two motors connected through a gear box to said mill provide for independently driving the finishing mills in speed coordinated relationship and for jointly driving the roughing mill.
