Description
Как известно, некоторые прокаливаемые материалы, как например, высокосортный листовой металл, полезно подвергать такой термической обработке (в особенности прокаливанию), при которой по возможности не происходит окислени , Так как при окислительном прокаливании помимо иолучающихс , благодар образованию окалины, нежелательных потерь материала и лишних расходов по дополнительной обработке , наблюдаютс вредные химические и физические изменени поверхности прокаливаемого предмета. Однако, с другой ;тороны, дл того, чтобы свести к минимуму потери тепла, св занные с восстановительным прокаливанием , последнее стараютс большею частью вести при услови х почти идеального теоретического сгорани или работа с таким количествсм воздуха, которое очень мало понижено по сравнению с теоретическим. Но в этом случае преимущества положительной восстановительной термической обработки не могут быть, конечно, достигнуты в полной мере.As is well known, some hardenable materials, such as high-grade sheet metal, are useful to undergo such heat treatment (especially calcination), at which oxidation does not occur, as much as possible, since oxidative calcination does not cause imitations, due to scaling, unwanted material loss and excess the cost of additional processing, there are harmful chemical and physical changes in the surface of the calcined object. However, on the other hand, in order to minimize the heat loss associated with reductive annealing, the latter tries to carry out most of the time under conditions of an almost perfect theoretical combustion or work with such a quantity of air that is very low compared to theoretical . But in this case, the advantages of positive restorative heat treatment cannot, of course, be fully achieved.

Означенный результат достигаетс благодар тому, что отход щие из рабочей камеры, частью несгоревшие, отработанные газы застав.ч ют сгорать далее без остатка, преимущественно внутри самой печи.This result is achieved due to the fact that the waste gases from the working chamber, partly unburned, exhaust gases cause burning further without residue, mainly inside the furnace itself.
Эта дополнительна операци состоит в том, что к неполностью сгоревшим газам, после оставлени ими рабочей камеры печи, подводитс в достаточном количестве свежий воздух дл горени , например, внутри регенераторов или рекуператоров или же перед входом в последние. Благодар происход щему при этом дополнительному сгоранию используетс оставша с св занной теплота.This additional operation consists in the fact that incompletely burnt gases, after they leave the working chamber of the furnace, fresh air is supplied in sufficient quantity for combustion, for example, inside regenerators or heat exchangers, or before entering the latter. Due to the additional combustion that occurs, the remaining heat from the associated heat is used.
Успешное действие предлагаемого способа может быть еще больше увеличено тем, что воздух дл дополнительного горени перед смешиванием его с газами предварительно подогреваетс . например, при помощи теплоты отход щих газов в канале дымовой трубы.
