摘要： The invention relates to a process for producing a profile with a cross section of different thicknesses from a flat metal strip (7) by means of roll-profiling. In this process, a roller pair (2.1, 2.2) produces at least one first recess on at least one side of the metal strip (7), said recess being widened by following roller pairs with incrementally enlarged recess width to form a region with a reduced material thickness (12.1, 12.2). The aim of the invention is to improve the production process, in particular to avoid the formation of undulations during the production of the profile. For this purpose, the invention provides that regions of the flat metal strip (7) which are arranged adjacent to the at least one recess (9.1, 9.2) are bent up before and/or during intervention by a roller pair (2.1, 2.2).

摘要： Disclosed are methods of producing steel rails having a high carbon content and being excellent in wear resistance and ductility from the slabs for rails. One method involves producing a steel rail having a high content of carbon, comprising finish rolling the rail in two consecutive passes, with a reduction rate per pass of a cross-section of the rail of 2-30%, wherein the conditions of the finish rolling satisfy the following relationship: S ≦ 800 / (C × T), wherein S is the maximum rolling interval time (seconds), C is the carbon content of the steel, wherein the carbon content is 0.85-1.40 mass%, and T is the maximum surface temperature (°C) of the rail head. Another method involves producing a steel rail with a high content of carbon, comprising: finish rolling the rail in three or more passes, with a reduction rate per pass of a cross-section of the rail of 2-30%, wherein the conditions of the finish rolling satisfy the following relationship: S ≦ 2400 / (C × T × P), wherein S is the maximum rolling interval time (seconds), C is the carbon content of the steel rail, wherein the carbon content is 0.85∼1.40 mass%, T is the maximum surface temperature (°C) of a rail head, and P is the number of passes, which is 3 or more. In addition to above, controlled additional amounts of V, Nb, N may be added to the steel rail and/or controlled rapid cooling of the rail after rolling may be accomplished to provide further improvements.

摘要： A rolling mill for the production of rails comprising a reversible intermediate working section (3) which receives broken down bars from an appropriate upstream break down rolling station (2) and passes them to a downstream finishing station (4). The intermediate working section (3) comprises a first (30) and a second universal stand (32), a high edging stand (31) placed between the first and the second universal stands (30, 32). The three stands (30, 31, 32) are placed at such a distance between each other that the bar can be simultaneously held in all three said stands (30, 31, 32) during rolling. A method for the rolling of rails with such a plant comprises the following operations in order: a rolling passage (U1) in the second universal stand (32); a rolling passage (E1) in the high edging stand (31); a rolling passage (U2) in the first universal stand (30).

摘要： The present invention relates to rolling process, particularly to the methods of double feed rolling with its following slitting in the rolling mill line and its following two-strand rolling, and can be implemented at two-high reversing and billet mills. The object of the present invention is to provide simultaneous double feed rolling in square passes, to improve finished product quality, particularly its macrostructure, giving a heavy reduction to ingot core part, to improve mill performance characteristics. Technological effects of the present invention are elimination of the feed twisting round its longitudinal axis in diagonal square passes, decrease of the ingot macrostructure defects due to axial porosity compacting and complete elimination of segregation. Slitting method of billet rolling is the method whereby a heated ingot is successively rolled in box, rhombic and diagonal square passes of the rolling mill. The method is different from the previously known methods because after the box pass the feed is rolled in a forming slitting pass having the shape of two ovals connected by a bridge and after that in rhombic and diagonal square passes it is further rolled into two feeds connected by a bridge, whereby the double diagonal square feed is slit at a breaking pass by means of round groove ridges having the radius R = (0,3...0,45)a, where "a" is a square billet side. 1il.

摘要： Previous methods for producing a profile section with varying wall thicknesses such as extrusion moulding, extrusion drawing or rolling are expensive and do not meet modern requirements in terms of dimensional accuracy. The objective of the invention is to provide a low-cost method for the production of profile sections with varying wall thicknesses, while guaranteeing dimensional accuracy. Strips are used as a starting material. Said strips are continuously fed into a welding installation and welded to each other on a longitudinal edge before being formed in a forming device. This enables profile sections with varying wall thicknesses to be produced at low cost and in a quick manner by using strips with the appropriate wall thicknesses. By simply changing the strips it is possible to produce different profile sections with low set-up times. The dimensional accuracy provided by the method is primarily directed towards the dimensional accuracy of strips that are used as a starting material. The inventive method is particularly suitable for strips that are made of aluminium, for instance, or steel with a wall thickness of up to 30 mm.
