Description

Т1 обрегение касаетс  обработки металлов давление и относитс  к способам правки. Известен способ правки путем нагрела п тен на поверхности выправл емого мета ла 1 . Недостатком известного способа  вл -етс  низкое качество правки проката изза неравномерности нагрева поверхности. Целью насто щего изобретени   вл етс повышение- качества правки выправл емого проката. Дл  этого предложено нагрев осущест вл ть по винтовой линии путем последовательного включени  источников нагрева. На фиг. 1 изображена схема правки по предлагаемому способу; на фиг. 2 - схема расположени  нагревателей; по сечению проката; на фиг. 3 - эпюра максимальных напр жений по сечению проката. Вьшравл емый прокат 1 перемещаетс  между роликами 2 и нагревагел ми 3-9, выполненными, например, в виде индукторов . Р дом с нагревател ми расположены спреернь е кольца с форсунками 10 и 11. . Индукторы соединень{ с цилиндрами дл  радиального перемещени  источников нагрева. Способ осуществл етс  следующим образом . При перемещении проката 1 через роли- (ки 2, которые фиксируют его положение, он быстро нагреваетс  одним индуктором, |например 3, затем индуктор 3 выключают Ц включают индуктор 4, затем включают BiaMyKTOpbi 5 и .6. В это же врем  в следующем сечении, где расположены анаЛогичные индукторы производ т лоследова тельно включение индукторов со сдвигом по фазе относительно индукторов 3-6. Дл  различных профилей этот сдвиг различен, чаще всего он равен 90 или 180 . При сдвиге на 90 в момент, когда осуществл ют нагрев, включен индуктор 3 и индуктор 8, далее одновременно включаютс  в работу другие инйукторы. При сдвиге на 18О одновременно работаю все ивдукто ры с поочередным включением по винтоT1 immersion relates to metal pressure treatment and relates to straightening methods. The known method of dressing by heating a spot on the surface of the straightened metal 1. The disadvantage of this method of ownership is the poor quality of the straightening of rolled products due to the uneven heating of the surface. The purpose of the present invention is to improve the quality of straightening straightened rolled products. For this, it has been proposed to heat the helix by successively turning on the heat sources. FIG. 1 shows the editing scheme for the proposed method; in fig. 2 is a layout of heaters; over the section of hire; in fig. 3 - plot of maximum stresses over the section of rolled products. Embedded rolled 1 moves between rollers 2 and heaters 3-9, made, for example, in the form of inductors. Next to the heaters are spray rings with nozzles 10 and 11.. Connectors with cylinders for radial movement of heat sources. The method is carried out as follows. When rolling 1 through the rollers (2, which fix its position, it quickly heats up with one inductor, | for example 3, then inductor 3 turns off C, turns on inductor 4, then turns on BiaMyKTOpbi 5 and .6. At the same time, in the following section where anaLogical inductors are located sequentially, the inductors are switched on with a phase shift relative to the inductors 3 to 6. For different profiles this shift is different, most often it is 90 or 180. With a shift by 90 at the moment heating is performed, the inductor is turned on 3 and inductor 8, then simultaneously Other injectors are involved in operation. When shifting by 18O, I work simultaneously with all the actuators with alternate switching on the screw
