Description
Предлагаемое изобретение касаете устройства дл электрического вагрева изделий путем погружени их в электропровод щую жидкость, через которую протекает электрический ток.The present invention relates to a device for electric vagreva products by immersing them in an electrically conductive liquid through which electric current flows.
Отличительной особенностью предлагаемого устройства вл етс использ-аваиие в качестве нагревательной камеры канала равномернЪго по длине сечени , обеспечивающего равномерный нагрев из/ елий сложной формы.A distinctive feature of the proposed device is its use as a heating chamber of a channel of uniform length along the section, which ensures uniform heating from / of a complex shape.
На чертеже приведена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Канал 2 посто нного сечени заполн етс электропровод щей жидкостью ,-имеющей высокую температуру кипени , при помощи которой замыкаютс концы вторичной обмотки 4 понижающего трансформатора.A constant section channel 2 is filled with an electrically conductive liquid, having a high boiling point, by means of which the ends of the secondary winding 4 of the step-down transformer are closed.
Деталь 3, предварительно подогрета в ванне 1, с целью повыщени к. п. д. установки, вводитс в канал 2. При включении тока электропровод ща жидкость и деталь, наход щиес в канале 2, начинают быстро нагреватьс , причем все части детали, как тонкие, так и массивные , нагреваютс с одинаковой скоростью, так как плотность тока в канале, а следовательно, и в детали , везде одинакова.Part 3, preheated in bath 1, in order to increase the efficiency of the installation, is introduced into channel 2. When the current is switched on, the electrically conducting fluid and the part in channel 2 begin to heat up quickly, and all parts of the part, like thin and massive, heated at the same speed, since the current density in the channel, and hence in the part, is the same everywhere.

Нагрета до заданной температуры деталь извлекаетс из канала и подвергаетс дальнейщей обработке (ковке, штамповке, прокатке, закалке в зоде или масле и т. д.).Heated to a predetermined temperature, the part is removed from the channel and subjected to further processing (forging, stamping, rolling, quenching in oil or oil, etc.).
Мелкие детали из углеродистой стали и крупные из легировалиой .могут обрабатыватьс изотермически в ваннб с жидким проводником по выходе из канала. Размеры ванны должны обеспечивать -минимальное изменение темнерат фы при охлаждении в ней деталей. В этом -случае не будет происходить образован.ие окалины, так как .нагреваемый объект не соприкасаетс с воздухолг до момента извлечени из установки .Small parts made of carbon steel and larger ones doped can be processed isothermally into a bath with liquid conductor as it leaves the channel. The dimensions of the bath should provide - minimal change in temperature when cooling parts in it. In this case the formation of scale will not occur, since the heated object does not come into contact with the airways until it is removed from the installation.
