Description
Производительность . существующих печей дл непрерывной газовой цементации с механической подачей ограничена тем, что карбюризующий газ быстро тер ет свою цементирующую способность вследствие распада углеводородов и при длинных печах газ не цементирует, нс приобретает способность обезуглероживани . По насто щему предложению при подводе карбюризирующих газов в средине печи и отвода отработавших газов или в обоих концах печи или в каком-либо одном конце полезна длина печи может быть увеличена, что вызовет и повышение производительности.Performance. existing furnaces for continuous gas cementation with mechanical feed is limited by the fact that carburizing gas quickly loses its cementing ability due to the decomposition of hydrocarbons and does not cement gas with long furnaces, ns acquires the ability of decarburization. According to the present proposal, when supplying carburizing gases in the middle of the furnace and exhaust gases either at both ends of the furnace or at one end, the useful length of the furnace can be increased, which will also lead to an increase in productivity.
На чертеже фиг. 1 изображает схему печи при отводе отработавших . газов в обоих концах; фиг. 2-схему печи при отводе отработавших газов со стороны выгрузки; фиг. 3 - схему печи при отводе со стороны загрузки.In FIG. 1 depicts the scheme of the furnace at the disposal of the exhaust. gases at both ends; FIG. 2-scheme of the furnace in the exhaust gases from the discharge; FIG. 3 is a diagram of the furnace during removal from the loading side.
Впуск карбюризирующего газа в муфель 7 печи производитс по трубе 2 (фиг. 1), где газ раздел етс на два потока 3 и 4. Поток 3 движетс к загрузочному концу печи, где он выпускаетс по трубе 5. Другой же поток 4 движетс к месту выгрузки изделий и выпускаетс из печи по трубе 6. Движение стальных деталей в печи происходит по стрелке 7 вначале навстречу газовому потоку 3, а затем движениеThe carburizing gas is injected into the furnace muffle 7 through pipe 2 (Fig. 1), where the gas is divided into two streams 3 and 4. Flow 3 moves to the charging end of the furnace, where it is released through pipe 5. The other stream 4 moves to the site unloading of products and is released from the furnace through pipe 6. The movement of steel parts in the furnace occurs along arrow 7 first towards the gas flow 3, and then movement
деталей совпадает с направлением потока 4. Регулировка потоков 3 н 4 газа производитс поворотом выпускных труб 5 к 6 вокруг их горизонтальных частей. Дл разъединени пространства цементации от мест загрузки и выгрузки устроены заслонки 8 и 9, а дл разъединени с наружным пространством-заслонки 10 VI 11.parts coincides with the direction of flow 4. Adjustment of the 3 N 4 gas flows is made by turning the exhaust pipes 5 to 6 around their horizontal parts. To separate the grouting space from the loading and unloading points, shutters 8 and 9 are arranged, and to separate them from the outer-shutter space 10 VI 11.
В цел х же более равномерного выпадани углерода при распаде углеводорода и возможности применени более бедных по углеводородам газов впуск газов производ т в нескольких местах 2 (фиг. 2 и 3), причем движение газа в печи или совпадает с движением издели (фиг. 2) или противоположно ему (фиг. 3).In order to more uniform carbon deposition during the decomposition of hydrocarbons and the possibility of using gases that are poorer in hydrocarbons, gases are introduced in several places 2 (Fig. 2 and 3), with the gas moving in the furnace or coinciding with the movement of the product (Fig. 2) or opposite to it (Fig. 3).
