摘要： A process and an ultracompact plant for the endless production of hot rolled steel strip comprising an ingot mold (15) that produces a very thin slab, having narrow sides with thickness in the range between 40 and 55 mm and a central swelling, at a speed in the range between 4 and 16 m/min. Such a slab, which displays a core in which the steel is still liquid, is passed through a vertical pre-rolling device (16) that reduces the thickness of the slab and flattens it. The solidified slab may thus be subjected to a first mild rolling by a conveyor (17) and, by forming a free curve, takes a horizontal position where it is subjected to a first surface descaling, a first rolling, a heating in an inductor (23), a second surface descaling and a series of reductions in a rolling mill (30) formed by at least two stands, by maintaining its temperature along the mill above the recrystallization point Ar3. Downstream of the rolling mill (30) there are provided a roller runway with cooling showers, a flying shear (33) for cutting to length the strip produced, pinch rolls and at least two spinning wheels (34) for the formation of coils of the hot rolled strip.

摘要： This invention is an electric arc furnace that can be continuously charged with ferrous materials, that can continuously melt the incoming charged materials, and that can semicontinuously tap molten steel by tilting to tap one side of the furnace or another. Continuous melting and refining can occur in lateral shafts adjacent to the central melting zone, and molten steel can be tapped from either of these shafts or directly from the central melting zone if desired. The furnace can be operated and tapped continuously, which provides many distinct advantages over what is currently available in the art.
