摘要： A process and an ultracompact plant for the endless production of hot rolled steel strip comprising an ingot mould (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 recrystallisation 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： Arranged in tandem are a pre-heating unit 6, a four-side hot-rolling mill 7 and a quenching/cooling unit 8. A starting material W1 is rapidly heated to a hot-rolling temperature using the unit 6 and hot-rolled into a modified cross-section steel wire W2 assuming a predetermined shape in cross section using the mill 7. The wire is then quenched under tension using the unit 8 immediately after its hot-rolling operation. The tension is applied to the wire by a pinch roll 9 driven by a motor 9a, which is combined with a torque converter. Consequently, there is no variation in tension, and no variation in cross-sectional dimension in the wire. Disposed behind the unit 8 in tandem is an in-line post-heating coil 10 to realize a continuous tempering operation, so that the wire free from any small-radius bend and having been heat-treated, can be produced through a substantially single process.

摘要： Continuously cast products (12) are often provided with surface defects such as oscillation marks (17) and other non-homogeneous structures in the cast state thereof during production in a casting die (11) of a continuous casting plant (10). Defects which render a strip useless for superior applications also frequently occur on the strip surface during subsequent milling of the slab (12") into a strip. The aim of the invention is to minimize said defects and provide the rolling mill with a slab (12") having a desired preliminary profile and an improved near-surface structure. Said aim is achieved by arranging a reducing roll stand (30) in the area of the bending rolls or straightening driver rolls (24) within the continuous casting plant (10). Said reducing roll stand (30) allows the cast billet (12) to be deformed in a specific manner at an early point in time while still having a high temperature and providing a high energy yield after being completely hardened such that the depth of the existing oscillation marks (17) on the cast billet surface (16) is reduced, the finely crystalline edge layer (18) is enlarged as a result of the energy being released which is introduced into the reducing billet (12') during said deformation process, and increased recrystallization occurs and the grains in the deformed edge zone (19) of the slab (12") are refined during the subsequent thermal treatment in a holding furnace (40).
