Description

II

Известен снособ термической обработки изделий , например труб, заключающийс  в том, что нагретую трубу быстро вращают относительно оси, охлажда  трубу как с внешней, так Н внутренней стороны.A known method for heat treatment of products, for example pipes, is that the heated pipe is rapidly rotated about an axis, cooling the pipe from both the outer and H inner side.

Этот снособ не позвол ет регулировать скоpocTi ) охлаждени  и предотвратить коробление.This method does not allow for adjusting the cooling rate and prevent warping.

Цель предлагаемого способа - регулирование скорости охлаждени  н предотвращение короблени .The purpose of the proposed method is to control the cooling rate and prevent distortion.

Дл  этого изделие при охлаждении вращают относнтельно оси, параллельной продольной оси издели  н лежащей вне его, так, что изделие совертпает часть оборота в зоне охлаждени , а остальную часть - вне ее.For this, the product rotates relative to the axis parallel to the longitudinal axis of the product and lying outside it, so that the product accomplishes part of the revolution in the cooling zone and the rest outside.

Оннсываемый снособ включает нагрев издели  до температуры закалки н носледуюн1,ее охлаждение в устройстве, сообщающем ему вращение относительно внешней оси, параллельной продольной оси издели . При этом изделие , одновременно но всей длиие, часть оборота совернгает в зоне водовоздутпной струи.Onsable removal method involves heating the product to a hardening temperature next to it, cooling it in a device that tells it to rotate about an external axis parallel to the longitudinal axis of the product. At the same time, the product, at the same time, but for the entire length, of the turnover in the zone of the water-air jet.

а часть - вне этой зоны. Интенсивное охлаждение поверхности издели  по всей его длине чередуетс  с нагревом за счет внутреннего теп .та, вследствие чего уменьп1аютс  остаточные нанр женн .and part is outside this zone. Intensive cooling of the surface of the product along its entire length alternates with heating due to internal heat, resulting in a decrease in residual particles.

Благодар  регулированию скорости охлаж дени  и предотвращению короблени , изобретемте позвол ет получить недеформированные изделп  с заданным комплексом свойств.Due to the regulation of the cooling rate and the prevention of distortion, we make it possible to obtain undeformed products with a given set of properties.

Предмет изобретени Subject invention

Снособ термической обработки изделий, например д;вутавра, включаюн ий нагрев до темнературы закалкн н последующее охлаждение, отличающийс  тем, что, с целью регулировани  скорости охлаждени  и предотвращени  короблени , изделие при охлаждении вращают относнтельно оси, параллельной продольной осн издели  н вне его, так. что изделие совернгает часть оборота в зоне охлаждени , а остальн ю часть - вне ее.The method of heat treatment of products, for example d; Wutaur, including heating to quenching tem- perature and subsequent cooling, characterized in that, in order to control the cooling rate and prevent distortion, the product rotates relative to the axis parallel to the longitudinal base of the product and outside it, so that . that the product commits a part of the revolution in the cooling zone, and the rest is outside it.
