Description
Известные способы печной сварки труб встык и сварки труб с нагревом токами повышенной частоты имеют р д существенных 1 едостаткоЕ . При печной сварке встык необходимо иметь печи значительной тепловой мощности, в то врем как нагревать весь штрипс до сварочно температуры нет необходимости. При сварке с нагревом токами высокой частоты штрипс приходитс свертывать в трубу в холодном состо нии на что затрачиваетс больша мошность и понижаетс производительность .The known methods of furnace butt welding of pipes and welding of pipes with heating by high-frequency currents have a number of significant 1 power. When butt-welding with furnaces, it is necessary to have furnaces of considerable heat output, while it is not necessary to heat the entire strip to a welding temperature. When welding with high-frequency heating, the strip must be rolled into a pipe in a cold state, which consumes a large amount of power and decreases productivity.
Предлагаемый способ пламенно-индукционной сварки труб позвол ет понизить температуру нагрева штрипса в печи, что уменьшает ее размеры и упрощ.ает конструкцию, а также позвол ет достигнуть концентрацию деформации в стыке и улучшить качество сварных труб. Осуществление описываемого способа обеспечиваетс применением скоростной нагревательной печи, обеспечивающей общий нагрев штрипса до 900- 1000°, индукционно высокочастотного нагревател , установленного между формовочным и сварочным калибром перед обдувкой воздухом, дл нагрева кромок до сварочной температуры.The proposed method of flame-induction welding of pipes makes it possible to lower the temperature of heating of the strip in the furnace, which reduces its size and simplifies the design, and also makes it possible to achieve a concentration of deformation at the joint and improve the quality of the welded pipes. The implementation of the described method is provided by using a high-speed heating furnace that provides general heating of the strips to 900-1000 °, an induction high-frequency heater installed between the molding and welding gauge before blowing air, to heat the edges to the welding temperature.
Предмет изобретени Subject invention
Способ непрерывной, сварки труб, отличающийс тем, что, с целью создани неравномерности нагрева штрипса по сечению, достижени сварочной температуры кромок и увеличени производительности, примен ют комбинированный пламенно-индукционный нагрев, при котором осуществл етс общий нагрев штрипса и местный индукционный нагрев только дл повышени температуры кромок.A method of continuous pipe welding, characterized in that, in order to create uneven heating of the strip over the cross section, to achieve the welding temperature of the edges and increase productivity, combined flame-induction heating is used, in which the general heating of the strip is carried out and local induction heating is used only to increase edge temperatures.
