Description
Основной недостаток поверхностной закалки изделий с нагревом кислородно-ацетиленовым пламенем заключаетс в том, что в конце операции в месте, где смыкаетс концами закаленна полоса поверхности , образуетс полоска отпуска.The main disadvantage of the surface hardening of products with heating with an oxygen-acetylene flame is that at the end of the operation, a tempering strip is formed at the place where the hardened surface of the surface closes.
По предлагаемому способу нагрев поверхности производ т двум горелками, которые перемещают вокруг неподвижного издели в противоположных направлени х, чем предотвращаетс по вление полоски отпуска.In the proposed method, the surface is heated by two burners that move around the stationary product in opposite directions, thus preventing the appearance of the tempering strip.
На фиг. 1-3 изображены различные рабочие положени горелок.FIG. 1-3, various burner operating positions are shown.
Наконечники газовых горелок 1 и вод ных сопел 2 смонтированы в одном блоке и могут перемещатьс вокруг неподвижно укрепленного издели . Дл закалки обычно примен ют два таких блока с горелками, перемещающимис в противоположных направлени х.The tips of the gas burners 1 and the water nozzles 2 are mounted in one unit and can move around a fixedly reinforced product. For quenching, two such blocks are usually used with burners moving in opposite directions.
Процесс закалки начинают, когда блоки наход тс под изделием 3. Вначале пускают в ход газовые горелки (фиг. 1,а); после того как плам горелок отрегулировано и изделие начало нагреватьс , подают через вод ные сопла воду (фиг. 1,6), котора омывает нагретые участки издели и закал ет их.The quenching process begins when the blocks are under the product 3. First, gas burners are put into operation (Fig. 1, a); After the burner flame has been adjusted and the product has begun to heat, water is fed through water nozzles (Fig. 1.6), which washes the heated parts of the product and quenches them.
ПрИ работе по этому способу положительным вл етс то, что закаленна зона все врем омываетс водой (фиг.. 2).In this method, it is positive that the hardened zone is constantly washed with water (Fig. 2).
Цикл заканчиваетс тем, что сход тс два газовых наконечника двух блоков, совместно нагревающих последний часток (фиг. 3). После этого плам тущат или уменьщают наполовину, или же наконечники автоматически отвод тс в сторону. Одновременно вода из обоих сопел 2 заливает последний участок, и он закаливаетс так же, как остальна поверхность издели .The cycle ends with the convergence of two gas tips of two blocks, which heat the latter together (Fig. 3). After that, the flames are half full or reduced, or the tips are automatically retracted to the side. At the same time, the water from both nozzles 2 fills the last section, and it quenches in the same way as the rest of the surface of the product.
Таким образом, в конце цикла плам не встречаетс с уже закаленной поверхностью, следовательно, не создаетс полоски отпуска.Thus, at the end of the cycle, the flame does not meet the already hardened surface, therefore, no tempering strips are created.
Предмет изобретени Subject invention
Способ поверхностной закалки изделий с нагревом кислородноацетиленовым пламенем, отличающийс тем, что дл устранени The method of surface hardening of products with heating with an oxy-acetylene flame, characterized in that
опасности образовани полоски отпуска нагрев поверхности производ т двум горелками, которые перемещают вокруг неподвижного издели в противоположных направлени х.the danger of forming the tempering strip is that the surface is heated by two burners that move around the stationary product in opposite directions.
