Claims (2)

ИЗ ВЫСОКОЛЕГИРОВАННЫХ чугунов . 36522 как на рубашках, обработанных известным способом, износ 41, в смену , т.е. в 10 раз больший. ---.-- Использование предложенного способа позвол ет. повысить износостойкость чугунных деталей при работе в абразивной среде. Дл  его осуществлени  целе- 5 сообразно примен ть более простое и более производительное оборудование сол ные ванны, что, в свою очередь, позвол ет значительно сократить длительность процесса термической обра- ю ботки за Счет сокращени  времени нагрева под закалку. Формула изобретени  1. Способ термической обработки изделий из высоколегированных чугунов , преимущественно высокохромйстых, включающий нагрев в интервале темпеJ5 31 ратур температура солидусэ, поеледующую закалку (нормализацию) и отпуск, от л и ч а ю щ и и тем, что, Ъ целью повышени  износостойкости , закалку (нормализацию) произ,вод т Многократно, при этом, последовательно повышают температуру нагрева под каждую последующую закалку ( нормализацию). FROM HIGH-alloyed cast iron. 36522 as on shirts treated in a known manner, wear 41, per shift, i.e. 10 times bigger. ---.-- The use of the proposed method allows. improve the wear resistance of cast iron parts when working in an abrasive environment. For its implementation, it is advisable to use simpler and more efficient equipment of salt baths, which, in turn, significantly reduces the duration of the thermal treatment process at the expense of reducing the heating time for quenching. Claim 1. Method of heat treatment of products from high-alloy cast iron, mainly high-chromium, including heating in the temperature range J5 31 of the solidarity temperature solidification, cooling and quenching (normalization) and tempering, in order to increase wear resistance , quenching (normalization), production, water, t Many times, at the same time, consistently increase the heating temperature for each subsequent quenching (normalization). 2. Способ по п.1,отличающ и и с   тем, что закалку (нормализацию ) изделий из чугуна ИЧХ12М производ т трехкратно: первую закалку ( нормализацию) ведут с температуры , вторую - с 850°С, и третью с 950°С.Источники информации, прин тые во внимание при экспертизе 1. Слободинский И.Н. и др. Извести  вузов. Машиностроение, 1973, № 3, с. 109-113.2. The method according to claim 1, characterized by the fact that the hardening (normalization) of articles made of cast iron ICH12M is performed three times: the first hardening (normalization) is carried out from the temperature, the second from 850 ° C, and the third from 950 ° C. Sources of information taken into account during the examination 1. I. Slobodinsky. and others. Lime universities. Mechanical Engineering, 1973, No. 3, p. 109-113.
