СПОСОБ ХИМИКО-ТЕРМИЧЕСКОЙ ОБРАБОТКИ ИНСТРУМЕНТА ИЗ БЫСТРОРЕЖУЩЕЙ СТАЛИMETHOD OF CHEMICAL-THERMAL TREATMENT OF TOOL FROM QUICKLY CUTTING STEEL

За влено 9 августа 1943 г. за Л 324434/22Filed on August 9, 1943 for L 324434/22

Основное авт. св. Л 63350 от 28 июн  1940 г. на им  Д. .. Прокоишнна Опубликовано н «Бюллетене изобретений .V 17 за 1959 г.The main author. St. L 63350 dated June 28, 1940 on them D. .. Prookishna Published n "Bulletin of inventions .V 17 for 1959

В ОСНОВНОМ авт. св. Л 63350 дл  повышени  стойкости инструмента из быстрорежущей стали предусмотрена его нитроцементаци  после полной термической обработки и шлифовани .BASIC Auth. St. L 63350 to increase the tool life of high-speed steel is provided for its carbonitriding after complete heat treatment and grinding.

Описываемый способ  вл етс  последующим приемом в обработке инструмента из быстрорежущей стали и состоит в том, что инструмент с предварительным нанесением на него цементационной пасты чополнтттельно обрабатывают в атмосфере аммиака цри температуре R20-560°.The described method is a subsequent reception in the processing of high-speed steel tools and consists in the fact that the tool with the preliminary application of cementation paste on it is treated in an atmosphere of ammonia at an temperature of R20-560 °.

Паста изготовл етс  из смеси, примерно состо щей и.ч 80% саж;) и 20% углекислого кали -натри  (ККаСОз) в водном растворе декстрина (100-150% от веса сажи). Смесь перемещиваетс  до густоты холодного машинного масла и наноситс  на инструмент путем двойной окраски или непосредственного погружени  его в пасту. После высыхани  пасты на воздухе инструмент загружаетс  в муфель печи со слабым током а.ммиака с температурой процесса 520-560° в зависимости от обрабатываемой марки стали инструмента.The paste is made from a mixture consisting of approximately 80% carbon black and;) and 20% potassium carbonate (KC-SO3) in an aqueous solution of dextrin (100-150% by weight of carbon black). The mixture is transported to the thickness of cold engine oil and applied to the instrument by double painting or directly immersing it in a paste. After the paste dries in air, the tool is loaded into the muffle of a low-current A.miak furnace with a process temperature of 520-560 °, depending on the type of tool steel being processed.

В муфельной камере поддерживаетс  давление 25-40 мм вод. сг. при подаче аммиака не более 2.5-3,0 л/мин.The muffle chamber maintains a pressure of 25-40 mm of water. cr. when applying ammonia no more than 2.5-3.0 l / min.

Глубина легированного сло  при такой обработке инструмента будет 0,03-0,08 мм. Стойкость режущего инструмента увеличиваете; примерно в 3-4 раза.The depth of the doped layer during such tool processing will be 0.03-0.08 mm. Increase the durability of the cutting tool; about 3-4 times.
