摘要： Process and ultracompact plant for continuous production of hot rolled steel strip comprising an ingot mould (15) which produces a very thin slab at a speed between 4 and 16 m/min, wherein the thickness of the oairrow sides is between 15 and 50 mm with a central swelling. Such slab has a core in which the steel is still liquid; it is run through a vertical pre-rolling device (16) which reduces the thickness of the slab, hence flattening it. The solidified slab can thus undergo a first light rolling process by means of a pinch roll (17) and, by forming a free curve, it moves to a horizontal position where it can undergo a second light rolling process by means of another pinch roll (22′), a heating process (if required) in an inductor (50), a superficial descaling process and a series of reductions in a rolling mill made up of at least three stands (20′, 20″, 20′″), thereby maintaining its temperature along the train above the Ar3 recrystallization point. Downstream of the rolling mill, there are a roller way (31) with cooling showers (32), flying shears (33) for cutting the strip to the required size, pinch rolls and at least two coilers (34) for forming coils of the hot rolled strip.

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).

摘要： A method and system are disclosed for receiving a hot rolled bar product from a rolling mill, and for delivering the bar product to a cooling bed. A shear subdivides the bar product into bar segments and alternately directs the bar segments to one or the other of two downstream intermediate paths for continued travel thereon. A switch on each of said intermediate paths alternately directs bar segments traveling thereon to one or the other of two respective downstream delivery paths for continued travel thereon to the cooling bed. Decelerators slow the bar segments traveling along the delivery paths.
