Изобретение относитс к области термической обработки и может быть использовано при изготовлении деталей их хромоникалевых и других высоколегированных сталей.The invention relates to the field of heat treatment and can be used in the manufacture of parts of their chromium and other high alloy steels.
При известном способе нагрева деталей в муфельных печах в среде защитного газа необходимо устанавливать специальное оборудование дл газоприготовлени .With the known method of heating parts in muffle furnaces in a protective gas environment, it is necessary to install special equipment for gas preparation.
Цель изобретени - упрощение способа нагрева деталей.The purpose of the invention is to simplify the method of heating parts.
Дл этого нагрев осуществл ют в среде углеводородного газа, подаваемого в первые 10-20 мин нагрева с расходом 0,5-2,5 на 1 м рабочего пространства муфел , а в оставщеес врем нагрева и выдержки с расходом 0,05-0,25 на 1 м рабочего пространства муфел .For this, heating is carried out in a hydrocarbon gas medium supplied in the first 10-20 minutes of heating with a flow rate of 0.5-2.5 per 1 m of muffle working space, and for the remaining heating and holding time with a flow rate of 0.05-0.25 on 1 m working space muffle.
В качестве углеводородного газа можно использовать природный газ. Сразу после загрузки деталей природный газ подают с расходом 0,5-2,5 на 1 м рабочего пространства муфел , а через 10-20 минNatural gas can be used as hydrocarbon gas. Immediately after loading the parts, natural gas is supplied at a rate of 0.5-2.5 per 1 m of muffle working space, and after 10-20 minutes
подачу газа уменьшают до 0,05-0,25 на 1 л рабочего пространства муфел .the gas supply is reduced to 0.05-0.25 per 1 liter of the working space of the muffle.
Онисываемый способ позвол ет получить на поверхности цементованных деталей оптимальную концентрацию углерода, обеспечивающую требуемые служебные свойства. После закалки с нагревом по данному способу образца из стали 12Х2Н4А концентраци углерода составл ет около 1,1%.This method allows to obtain the optimum concentration of carbon on the surface of cemented parts, providing the required service properties. After quenching with heating in this method of a sample of 12X2H4A steel, the carbon concentration is about 1.1%.
Предмет изобретени Subject invention
Способ нагрева деталей под закалку в муфельных печах в среде защитного газа,The method of heating parts for quenching in muffle furnaces in a protective gas environment,
отличающийс тем, что, с целью упрощени способа нагрева, например, цементованных деталей, нагрев осуществл ют в среде углеводородного газа, подаваемого в первые 10-20 мин нагрева с расходом 0,5-2,5 characterized in that, in order to simplify the method of heating, for example, cemented parts, heating is carried out in a hydrocarbon gas medium supplied in the first 10-20 minutes of heating with a flow rate of 0.5-2.5
на 1 м рабочего пространства муфел , а в оставщеес врем нагрева и выдержки деталей с расходом 0,05-0,25 на 1 м- рабочего пространства муфел .at 1 m of the muffle working space, and in the remaining time of heating and holding parts with a flow rate of 0.05-0.25 per 1 m, the muffle working space.
