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.
