Изобретение относитс к сварочному производству и может быть использовано дл автоматического управлени процессом электронагрева зоны сварного шва при термообработке труб в линии трубоэлсктросварочного стана.The invention relates to welding production and can be used for automatic control of the process of electrical heating of the weld zone during heat treatment of pipes in the line of the tubular electric welding mill.
Известны способы автоматического управлени процессом электронагрева путем изменени мощности нагревательного устройства в зависимости от различных параметров сварочного процесса 1.Methods are known for automatically controlling the electric heating process by varying the power of the heating device depending on various parameters of the welding process 1.
Наиболее близким техническим решением к предлагаемому вл етс способ автоматического управлени процессом изготовлени электросварных труб, предусматривающий изменение мощности нагревательного устройства дл сварки труб в зависимости от сигнала, характеризующего отклонение температуры нагрева от заданного значени , т. е. в зависимости от изменени интегрального потока излучени очага нагрева, измеренного фотодатчиком, расположенным на таком рассто нии от очага нагрева, при котором этот очаг при любых изменени х его размеров остаетс в области визировани 2.The closest technical solution to the present invention is a method for automatically controlling the process of manufacturing electric-welded pipes, which involves changing the power of a heating device for welding pipes depending on a signal that characterizes the deviation of the heating temperature from a predetermined value, i.e., depending on the change in the integral radiation flux measured by a photosensor located at such a distance from the center of heating at which this center with any changes in its dimensions staets in 2 of sight.
Недостатком указанного способа вл етс то, что дл термообработки требуетс фотодатчик и регул тор нагрева на каждое нагревательное устройство, что снижает надежность системы управлени .The disadvantage of this method is that heat treatment requires a photo sensor and a heating controller for each heating device, which reduces the reliability of the control system.
Целью изобретени вл етс упрощение системы управлени процессом изготовлени электросварных труб дл повышени ее надежности.The aim of the invention is to simplify the process control system for the manufacture of electric-welded pipes to increase its reliability.
Поставленна цель достигаетс тем, что в известном способе автоматического управлени процессом изготовлени электросварных труб, предусматривающем изменение мощности нагревательного устройства дл сварки труб в зависимости от сигнала , характеризующего отклонение температуры нагрева от заданного значени ,The goal is achieved by the fact that in the known method of automatic control of the process of manufacturing electric-welded pipes, which involves changing the power of the heating device for welding pipes depending on the signal characterizing the deviation of the heating temperature from a predetermined value,
сигнал, управл ющий мощностью нагревательных устройств дл сварки, используют в качестве управл ющего сигнала нагревательными устройствами дл термообработки сваренных труб.The signal controlling the power of the heating devices for welding is used as a control signal by heating devices for the heat treatment of welded pipes.
На чертеже приведена схема осуществлени предлагаемого способа автоматического управлени процессом изготовлени электросварных труб, где 1 - нагревательное устройство дл сварки труб; 2 - регул тор режима сварки; 3 - фотодатчик; 4 - задатчик; 5 - сравнивающее устройство; 6 - нагревательное устройство дл термообработки.The drawing shows a scheme for implementing the proposed method for automatically controlling the process of manufacturing electric-welded pipes, where 1 is a heating device for welding pipes; 2 - welding mode controller; 3 - photo sensor; 4 - setting device; 5 - comparing device; 6 - heating device for heat treatment.
