Description
Известны способы индукционного нагрева заготовок.Known methods of induction heating of the workpieces.
Цель изобретени -увеличить скорость нагрева заготовок.The purpose of the invention is to increase the heating rate of the blanks.
Предлагаемый способ нагрева тонкостенных металлических изделий заключаетс в создании дополнительного теплового потока со стороны предварительно разогретой футеровки индуктора и металлического или графитового экранов, от которых нагревают футеровку .The proposed method of heating thin-walled metal products consists in creating an additional heat flux from the side of the preheated lining of the inductor and the metal or graphite screens from which the lining is heated.
Процесс провод т в две стадии. На первой стадии нагревают экран, размещенный внутри индуктора, и футеровку путем лучистого теплообмена с экраном до температуры, превышающей заданную температуру нагрева издели .The process is carried out in two stages. At the first stage, the screen placed inside the inductor is heated, and the lining is radiated by heat exchange with the screen to a temperature above the predetermined temperature of the product.
На второй стадии изделие помещают в кольцевую область между футеровкой индуктора и экраном. Размеры кольцевого зазора выбирают таким образом, что вс мощность наведенных токов выдел етс только в изделие .In the second stage, the product is placed in the annular region between the lining of the inductor and the screen. The dimensions of the annular gap are chosen in such a way that the entire power of the induced currents is allocated only to the product.
