Description
(54) СПОСОБ ПОЛУЧЕНИЯ ЭКЗОТЕРМИЧЕСКОЙ АТМОСФЕШ(54) METHOD FOR OBTAINING EXOTHERMAL ATMOSFESH
Изобретение относитс термообработке металла в контролируемыхатмос ферах.The invention relates to the heat treatment of a metal in controlled atmospheres.
Известен способ получени контроглируеАШх атмосфер, заключающийс в частичном сжигании природного газа с коэффициентом расхода воздуха 0,550 ,95, охлаждении продуктов сгорани до 20-30с, осушке в рефрижераторе с последующей ос покой на тверде адсорбенте С15.A known method for producing counter atmospheric atmospheres consists in partial combustion of natural gas with an air flow rate of 0.550, 95, cooling of the combustion products to 20-30 seconds, drying in a refrigerator, followed by settling on a solid C15 adsorbent.
Недостатками указанного способа вл ютс подстуживание изделий в печи в месте ввода контролируемой атмосферы и неравномерный состав ее по объему рабочего пространства печи.The disadvantages of this method are the pressing of the products in the furnace at the point of entry of the controlled atmosphere and its uneven composition by volume of the furnace working space.
Наиболее близким к предлагаемому вл етс способ получени экзотермической атмосферы дл термической обработки , включающий сжигание углеводородных газов с коэффициентом расхода воздуха 0,6-0,95, охлаждение продуктов сгорани до ЗО-ЗО С с отводом конденсата из системы, очистку их от нежелательных примесей и подачу готовой атмосферы в печь 2.The closest to the present invention is a method of obtaining an exothermic atmosphere for heat treatment, including the combustion of hydrocarbon gases with an air flow rate of 0.6-0.95, cooling of the combustion products to ZO-ZO C with the removal of condensate from the system, their cleaning feeding the finished atmosphere into the oven 2.
Недостатками известного способа вл ютс неравномерный состав контро лируемой атмосферы по всему объему рабочего пространства печи и наличиеThe disadvantages of this method are the uneven composition of the controlled atmosphere throughout the entire working space of the furnace and the presence

Цель изобретени - стабилизаци защит|1Ой а-сыосферы по составу k температуре .The purpose of the invention is to stabilize the protection | 1Oi of the ayxyphere according to the composition of k temperature.
Поставленна цель достигаетс тем, что в способе получени экзотермической атмосферы дл термической обработки , включакнцем сжигание углево10 Д1РРОДНЫХ газов с коэффициентом расхода воздуха 0,6-0,95 и охлаждение продуктов сгорани до 20-30°С с отводом конденсата, после охлаждени продуктов сгорани их подогревают в при15 сутствии катализатора до температуры процесса термообработки.The goal is achieved by the fact that in the method of obtaining an exothermic atmosphere for heat treatment, including the combustion of hydrocarbon gases with a flow rate of 0.6-0.95 and cooling of the combustion products to 20-30 ° C with condensate drainage, after cooling the combustion products in the presence of a catalyst, it is heated to the temperature of the heat treatment process.
Кроме того, продукты сгорани после охлаждени и перед подогревом их дополнительно осушают и очищают от In addition, the products of combustion, after cooling and before heating, are additionally dried and cleaned.
20 двуокиси углерода.20 carbon dioxide.
Способ осуществл етс следующим образом.The method is carried out as follows.
Углеводородный газ, например ме25 тан, смешивают с воздухом с коэффициентом расхода 0,6-0,95, сжигают полученную смесь при 950-1200 с и направл ют образовавшиес продукты сгорани в теплообменный аппарат дл , Hydrocarbon gas, such as methane, is mixed with air with a flow ratio of 0.6-0.95, the mixture is burned at 950-1200 s and the resulting combustion products are sent to a heat exchanger for
