Method of rolling a band of metal with adjustment of its lateral position on the one hand and adapted rolling mill

The method involves adjusting a side position of metallic strip (B) by determining a value representing a side position along a line transverse to the movement direction, and calculating the algebraic deviations between the position and a reference position (6). Value of additional tilting to be applied to each of cages (1, 2) is calculated based on the deviations to reduce the deviations under a preset threshold. Respective set point of the tilting is transmitted to each of the cages. Operations are repeated at preset time interval until the strip is not clamped in one of the cages. An independent claim is also included for a device for controlling side position of a strip inside a rolling mill of metallic products, comprising sensors.

Method of defining rolled material state, particularly, that of rough strip

FIELD: process engineering. SUBSTANCE: invention relates to control over state (S1, S2, S3) of rolled material (G, GX), in particular, rough strip. Said state is defined by indications of wedging or camber of rolled material (G, GX). For this, rolled material (G, GX) is changed from initial state (S1) by rolling at roughing stand 1 and introducing strain (σ) to said material by means of extra machining means 7, 8, into intermediate state (S2). Note here that rolled material (G) is changed from intermediate state (S2) by means of, at least, one machining unit (A1, A2, A3,…AN) into final state (S3). Note here that, at this stage, defined is if rolled material (G, GX) is to be fed into said machining unit (A1, A2, A3,…, AN) intermediate state of which requires wedging or camber other than zero to ensure preset final state (S3'). This condition dully allowed for, duly intermediate state (S2) is set by control and/or adjustment of stand 1 and/or machining means 7, 8.

Method includes influencing the geometry of the rolled material in the form of slabs or a roughing strip during the rolling process carried out in the rolling stand by means of two processing units (6, 8), which are made in the form of a vertical stand, a lateral guide or a lateral force device, and are located on both sides of the rolled material, herewith force adjustment is performed in one processing unit (6) basing on nominal force (F), and in the other processing unit (8) position adjustment is performed. Improvement in the geometry of rolled material (4), in particular when processing asymmetric rolled material (4), is achieved due to the fact that a midpoint between two processing units (6, 8) is preset, wherein position-adjusted processing unit (8) is moved in accordance with the movement of force-adjusted processing unit (6) with a change in the interval between them in such a way, that midpoint (14) between both processing units (6, 8) always remains in the preset position. EFFECT: method of rolling is proposed. 25 cl, 2 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 647 417 C2 (51) МПК B21B 13/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B21B 13/06 (2006.01) (21)(22) Заявка: 2015103124, 13.06.2013 (24) Дата начала отсчета срока действия патента: (73) Патентообладатель(и): ПРАЙМЕТАЛЗ ТЕКНОЛОДЖИЗ ДЖЕРМАНИ ГМБХ (DE) Дата регистрации: 15.03.2018 (56) Список документов, цитированных в отчете о поиске: WO 2011/080226 A2, 07.07.2011.

Method of calibrating two interacting rolls at rolling mill

FIELD: process engineering. SUBSTANCE: invention relates to rolling, particularly, to calibration of rolling stand 3. Prior to rolling, set of rolls is compressed by preset radial force to measure rolling stand strain, preferable, at cylinder-and-piston unit 6, 7. To define symmetric strain source and/or elongation of rolling stand 3, relative position of rolls set turn is defined. Said position of rolls set turn and/or rolling stand stiffness modules M defined therefrom are used in subsequent rolling for calculations intended for mounting the set of rolls. Note here that rolls 1, 2 allow relative axial rearrangement. Note here that definition of turn position for setting symmetric strain source and/or definition of said modulus M are determined with said rolls 1, 2 shifted relative to each other. Defined said turn position and/or stiffness modulus M are loaded into memory to be used for further computation of turn position and/or mounting rolls set in rolling. EFFECT: higher precision of rolling. 4 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 476 280 (13) C1 (51) МПК B21B 38/10 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2011129595/02, 17.12.2009 (24) Дата начала отсчета срока действия патента: 17.12.2009 (72) Автор(ы): ЗАЙДЕЛЬ Юрген (DE), ЙЕПСЕН Олаф Норман (DE) (73) Патентообладатель(и): СМС ЗИМАГ АГ (DE) R U Приоритет(ы): (30) Конвенционный приоритет: 18.12.2008 DE 102008063514.6 27.06.2009 DE 102009030792.3 (45) Опубликовано: 27.02.2013 Бюл. № 6 2 4 7 6 2 8 0 (56) Список документов, цитированных в отчете о поиске: JP 60030509 А, 16.02.1985.
