In the continuous manufacture of hot strip material, slabs are produced by a pair of continuous casters and heated to a rolling temperature in a bi-level roller hearth furnace. Hot slabs are discharged from the bi-level furnace alternately from its upper and lower roller hearths. The slabs are then scarfed to clean oxide scale from both sides and to heat the slabs to a temperature of about 2300.degree. F. The scarfed ends of adjacent slabs are overlapped and passed through a two high slab mill welder wherein the overlapped ends are joined together. The joined slabs are thereafter finish rolled to strip gauge in a continuous multi-stand hot strip mill.

Method and apparatus for continuously hot rolling strip

A mounting and handling arrangement for a hydraulic force applying system used to adjust and maintain a passline in a rolling mill stand comprises a hydraulic device having a manifold member extending through the top of a housing and connected to a piston cylinder assembly. Manifold member carries a position transducer along with its electrical components and hydraulic line connections communicating with internal passages for delivering hydraulic fluid to the piston cylinder assembly. Cradle assembly comprising a plate and brace members receive and support the hydraulic force assembly for its insertion and removal from the roll stand.
