Description
Изобретение относитс к области термической обработки изделий, в частиости к закалке с нагревом нх токамн высокой частоты.The invention relates to the field of heat treatment of products, in part to quenching with heating of high-frequency tokamn.
Известен снособ ненрерывно-носледовательной закалки изделий с нагревом их токами высокой частоты, осуществл емый иогружснием изделий в расположенный пепосредственно иод индуктором бак с закалочной средой, например маслом.A known method of continuous continuous hardening of products with their heating by high-frequency currents is carried out by immersing the products in a tank with a quenching medium, such as oil, located directly at the inductor.
Иедостаток указанного снособа заключаетс в том, что масло может восиламен тьс .The disadvantage of this procedure is that the oil can rise.
Целью изобретени вл ете исключение загорани закалочной среды. Это достигаетс тем, что в зону погружени издели иепрерывно подают закалочную среду, например охлажденное масло.The aim of the invention is to eliminate the ignition of the quenching medium. This is achieved in that a quenching medium, such as cooled oil, is continuously supplied to the immersion area of the product.
Изделие, нагретое в индукторе, установленном непосредственно над новерхностью масла, пеирерывно-последовательпо опускаетс в масло . Посто нпое иоступлеппе к нагретой до гсмнературы закалки поверхности издели холодио о масла преп тствует его загорапню.The product heated in the inductor, installed directly above the surface of the oil, is continuously lowered into the oil. A constant access to the hardening of the cold-oil product's surface, which is heated to temperature, prevents the product from becoming cold.
Описываемый способ обеспечивает также повышеппе иропзводптельпости труда при обработке длинномерных изделий различной копф1нлрации, изготовлеппых из легированных сталей.The described method also provides for increasing the labor productivity during the processing of long products of various types made from alloyed steels.
Предмет изобретени Subject invention
Снособ неирерывно-носледовательной закалки пзделий с нагревом нх токами высокой частоты , осуществл емый ногрул ением изделий в расположеииый пепосредственно под индуктором бак с закалочной средой, способно11 восиламен тьс , отличающийс тем, что, с целью исключени загорапп закалочной среды , ее пенрерывно нодают в зону ногруженн издели .The method of non-continuous successive quenching of hillocks with heating them with high-frequency currents, carried out by turning the products into the quenching medium tank directly under the inductor, is able to heal, characterized by the fact that, in order to exclude the quenching medium, it is possible for them to reside at their own pace. products.
