Description
Известны способы непрерывной печной сварки и индукпиопной радиочастотной сварки труб.Known methods of continuous furnace welding and indukopiopnoy radiofrequency pipe welding.
Предложенный способ изготовлени сварных труб отличаетс тем, что подогрета в печи до температуры 300-980°С заготовка формуетс в двух клет х, после чего производитс индукционный догрев и сварка кромок. Это отличие позвол ет сваривать различные металлы и сплавы в одном агрегате, сокращает длину агрегата, уменьшает вес оборудовани , увеличивает производительность и повышает качество продукции.The proposed method of manufacturing welded pipes is characterized in that the billet is preheated to a temperature of 300-980 ° C. The billet is molded in two cages, after which induction heating and edge welding are performed. This difference allows welding various metals and alloys in one unit, reduces the length of the unit, reduces the weight of the equipment, increases productivity and improves product quality.
В линии подготовки готов т «бесконечный штрипс, который поступает в печь и равномерно нагреваетс до температуры редуцировани (300-980°С). После нагрева со штрипса обдувом удал етс окалина и из него в 2-3 клет х формуетс трубна заготовка швом вниз. За клет ми устанавливаетс нож, удерживаюа ий и направл ющий кромки.In the preparation line, an "endless strip" is prepared, which enters the furnace and is uniformly heated to the reduction temperature (300-980 ° C). After heating, scale is removed from the strip by blowing and tube billet is molded down from it in 2-3 cells. A knife is installed behind the cages, holding and guiding the edges.
Сформованна трубна заготовка поступает на сварочный стан, где производитс индукционный радиочастотный догрев кромок и сварка трубы. После сварки удал етс грат и «бесконечна труба поступает па редукционный или калибровочный стан, где ей придаютс окончательные размеры по диаметру и толщине стенки.The molded tubular billet enters the welding mill where radiofrequency induction reheating is performed and the pipe is welded. After welding, the burr is removed and the "endless tube enters the reducing or calibration mill, where it is given its final dimensions in diameter and wall thickness.
Способ позвол ет сваривать трубу из любого металла. Сварной шов не отличаетс от сплошного металла.The method allows welding of a pipe of any metal. The weld is no different from solid metal.
