Изобретение относитс к литейном производству, в частности к литью по газифицируемым модел м.The invention relates to foundry, in particular, to casting by gasifiable models.
Цель изобретени - предотвращени дефектов на поверхности лить , снижение его себестоимости.The purpose of the invention is to prevent defects on the surface of the casting, reducing its cost.
На чертеже приведена литейна орма с газифицируемой моделью.The drawing shows a casting mold with a gasified model.
Газифицируема модель 1, котора имеет газоотводный канал 2 и литниковую систему 3, устанавливают в контейнер 4 и засыпают песком. Высота модели 200 мм, длина 200 мм, средн толщина стенки 22 мм. Модель предварительно покрывают краской: маршалит,прокаленный 68 мас.%, 3%-ный раствор поливинилбутирал в спирте в количестве 32 мас.%.Gasified model 1, which has a gas outlet channel 2 and gating system 3, is installed in container 4 and covered with sand. The height of the model is 200 mm, the length is 200 mm, the average wall thickness is 22 mm. The model is pre-coated with paint: marshalite, calcined 68% by weight, 3% solution of polyvinyl butyral in alcohol in the amount of 32% by weight.
Газоотводный канал 2 состыковывают с керамической трубкой 5. На выходе газоотводного канала устанавливают предохранительный клапан 6 в виде стакана, открьшающего каСоставитель В.Фоменко Редактор Л.Авраменко Техред 3,ПалийThe gas exhaust duct 2 is joined to the ceramic tube 5. At the outlet of the exhaust gas duct, a safety valve 6 is installed in the form of a glass, which is opened by V. Fomenko, Editor L. Avramenko Tehred 3, Paliy

нал при достижении избыточного давлени в зазоре 0,005-0,04 Mlla.Выбор оптимального давлени из приведенного интервала зависит от геометрии 5 отливки и температуры расплава. Снижение избыточного давлени в зазоре расплав - газифицируема модель ниже 0,005 МПа приводит к обвалу формы , а превышение 0,04 Ша к искаже- 10 нию геометрии отливки.when the overpressure in the gap reaches 0.005-0.04 Mlla. The choice of the optimal pressure from the given interval depends on the geometry of the 5 casting and the temperature of the melt. A decrease in the overpressure in the melt gap — the gasified model below 0.005 MPa leads to a collapse of the mold, and an excess of 0.04 Sha to a distortion of the geometry of the casting.
Реализаци предлагаемого способа позвол ет примен ть менее газопрони- цаемь1е, но более огнеупорные краски, стабилизирует скорость подъема ме- (5 талла и улучшает чистоту поверхности отливки.The implementation of the proposed method allows the use of less gas permeability, but more refractory paints, stabilizes the rate of lifting of metal (5 tal and improves the cleanliness of the surface of the casting.
Подача в зазор металл-газифициру- ема модель углекислого газа дл 20 окислени продуктов термодеструкции модели позвол ет дополнительно повысить чистоту поверхности отливки и качество лить .The supply of a carbon dioxide model to the metal-gasifying gap for oxidizing the thermal decomposition products of the model makes it possible to further improve the cleanliness of the casting surface and the quality of the casting.
