Изобретение относитс к металлургии , конкретнее к высокотемпературной термомеханической обработке быстрорежущих инструментальных сталей.The invention relates to metallurgy, and more specifically to the high-temperature thermomechanical processing of high-speed tool steels.
Целью изобретени вл етс улучшение красностойкости, ударной в зкости , прочности и эксплуатационной стойкости стали.The aim of the invention is to improve redness, toughness, strength and service resistance of steel.
П р и м е р. Заготовки быстрорежущей стали нагревают до температуры закалки, .подстуживают до температур на 90-240 С ниже прин тых температур начала ковки, куют на паровоздушном молоте-обжати ми в течение (0,373-0,718) .102 с, которое адекватно отношению максимальной степени 0,41-0,95 к скорости 110-133 очаге деформации. При этом, ut (2,41-3,89)-. . Измер ют величину осадки дл определени средней степени деформации и вычисл ют максимальную степень деформации . Контроль температуры и вре- мени осуществл ют зачеканенными термопарами в центральную область очага деформаций и осциллографированием.PRI me R. High-speed steel billets are heated to quenching temperature. They are boosted to temperatures of 90-240 ° C below the accepted forging temperatures, forged on a steam-air hammer for about 0.373-0.718 seconds, which is adequate for the ratio of the maximum degree of 0.41 -0.95 to the speed of 110-133 deformation zone. At the same time, ut (2.41-3.89) -. . The precipitation is measured to determine the average degree of deformation and the maximum degree of deformation is calculated. Temperature and time are controlled by staking thermocouples into the central region of the deformation zone and oscillography.

After quenching, a threefold tempering is performed at 550-560 ° C (air cooling). The drills are made and tested for durability (the material being processed, the feed rate, the depth of cut are the same in all cases).
