Description
Изобретение относитс к способам высокотемпературной обработки быстрорежущи.х ста.лей.This invention relates to methods for high-temperature treatment of high-speed steel.
Из основного авт. св. № 449941 известен способ термомеханической обработки быстрорежущей стали, включающий ауттенитизацию при температуре более 115б°С, подстуживание до 400-600°С, скоростной нагрев до температуры 960-1150°С, гор чую деформацию со степенью обжати более 0,7, закалку и многократный отпуск.From the main auth. St. No. 449941, there is a known method for the thermomechanical treatment of high-speed steel, including auttenitization at a temperature of more than 115b ° C, cooling to 400-600 ° C, high-speed heating to a temperature of 960-1150 ° C, hot deformation with a degree of reduction of more than 0.7, quenching and multiple vacation.
Способ позвол ет увеличить стойкость инструмента.The method allows to increase tool life.
Целью изобретени вл етс ювьннение твердости и красностойкости быстрорежущей стали.The aim of the invention is to evaluate the hardness and red hardness of high-speed steel.
Это достигаетс тем, что после подстуживани стали производ т изотермическую выдержку в ультразвуковом поле.This is achieved by the fact that after pressing the steel is produced isothermal exposure in the ultrasonic field.
Способ осуществл ют следующи.м образом .The method is carried out in the following manner.
Провод т термомеханическую обработку прутков из быстрорежущей стали. Обработка включает аустенизацию исходных заготовок диаметром 20 мм при температуре 1290°С в бариевой ванне, подстуживаниеThermomechanical treatment of high-speed steel rods is carried out. Processing includes austenization of the original billet with a diameter of 20 mm at a temperature of 1290 ° C in a barium bath, podstuzhivanie
до и изотермическую выдержку при 500°С в ультразвуковом поле, скоростной нагрев до температур п,ластической деформации , выдавливание со степенью обжати .78. охлаждение выдавленных изделий в масле и последующий трехкратный отпуск при температуре 560°С.before and isothermal exposure at 500 ° C in an ultrasonic field, high-speed heating to temperatures n, elastic deformation, extrusion with a degree of reduction .78. cooling of the extruded products in oil and subsequent three-time tempering at a temperature of 560 ° С.
Озвучивание образцов производ т в течение 60 мин. Излучателем ультразвука служит магнитостриктор, представл ющий собой пакет пермендюровых пластин.Samples are scored for 60 minutes. An ultrasound emitter is a magnetostrictor, which is a package of permendure plates.
Ультразвуковые колебани передают образцу через магнитостриктор и волновод. Дл питани магнитостриктора используют генератор УЗГ-10. Выдавливание осуществл ют на кривощипном прессе К 1 17 в штампе, предназначенном .ал гор чего гидродинамического выдавливани заготовок режущего инструмента диаметром 8-22 мм.Ultrasonic vibrations are transmitted to the sample through a magnetostrictor and a waveguide. A UZG-10 generator is used to power the magnetostrictor. The extrusion is carried out on a K-ram press K 1 17 in a die designed for hot-pressing hydrodynamic extrusion of cutting tool blanks with a diameter of 8-22 mm.
Результаты исследований представлены в таблице.The research results are presented in the table.
