Description

Печи к аппаратам дл  вырашиваки  монокристаллов тугоплавких веществ из порошка в токе гор чего газа, содержащие муфель с теплоизол ционной обмазкой, верхнюю и нижнюю крышки наружного цилиндра с приспособлени ми дл  креплени  к общей станине и дл  наблюдени  за процессом кристаллизации, известны.Furnaces to the apparatus for the production of single crystals of refractory substances from powder in a stream of hot gas, containing a muffle with heat-insulating coating, upper and lower covers of the outer cylinder with fixtures for attaching to a common frame and for observing the crystallization process, are known.

Предлагаема  печь в отличие от известных выполнена с кольцевой камерой, образованной между муфелем и наружным цилиндром и снизу ограниченной фигурным кольцом, а сверху крышкой. Така  конструкци  печи позвол ет улучшить тепловой режим работы печи и создать дополнительный тепловой барьер.The proposed furnace, in contrast to the known ones, is made with an annular chamber formed between the muffle and the outer cylinder and at the bottom limited by the shaped ring, and on top by the lid. This design of the furnace allows to improve the thermal mode of operation of the furnace and to create an additional thermal barrier.

На чертеже изображена схема предлагаемой печи в разрезе.The drawing shows a diagram of the proposed furnace in the section.

В муфеле / происходит сгорание водородо-кислородной смеси, поступающей из сопла горелки 2. Кольцева  камера образуетс  между муфелем / с теплоизол ционной обмазкой 3, наружным цилиндром 4 и снизу ограничена фигурным кольцом 5, а сверху крышкой 6. Через отверсти  в фигурном кольце 5 гор чие газы и избыточный водород, необходимый по технологии выращивани  монокристаллов, поступают в кольцевую камеру. Отверсти  в днище 7 служат дл  подсоса воздуха, необходимого дл  сгорани  избыточного водорода. Вверху над камерой находитс  кольцевой сборник 8 дл  отработанных газов. Снизу печь имеет шлюз, закрывающийс  съемной втулкой 9.In the muffle /, the hydrogen-oxygen mixture from the burner nozzle 2 is burned. The annular chamber is formed between the muffle / with thermal insulating coating 3, the outer cylinder 4 and the bottom is bounded by the shaped ring 5, and from the top by the lid 6. Through the holes in the shaped ring 5 mountains The gases and excess hydrogen required by the single crystal growing technology enter the annular chamber. The holes in the bottom 7 serve to draw in the air necessary for the combustion of excess hydrogen. Above the chamber is a ring collector 8 for exhaust gases. Below the furnace has a gateway, which is closed by a removable sleeve 9.

Таким образом, при выращивании монокристаллов в предлагаемой печи в кольцевой камере образуетс  тепловой барьер, преп тствующий отдаче тепла от муфел  / печи в окружающую среду.Thus, when growing single crystals in the proposed furnace, a thermal barrier is formed in the annular chamber, which prevents the heat transfer from the muffle / furnace to the environment.

Предлагаема  конструкци  печи более инерционна по сравнению с известными и снижает температурные градиенты в объеме печного пространства за счет лучшего аккумулировани  гор чих газов, позвол  The proposed furnace design is more inertial in comparison with the known ones and reduces temperature gradients in the furnace space volume due to better accumulation of hot gases, allowing
