Description
Предлагаемый способ и приспособление предназначаютс , главным образом, дл случаев, когда желательно получение ковкого чугуна отдельными порци ми впределах вместимости копильника вагранки. Свойства сплавов могут по желанию колебатьс Б пределах от состо ни железа до состо ни обыкновенного ваграночного чугуна .The proposed method and device is mainly intended for cases when it is desirable to obtain ductile iron in separate portions within the limits of the cupola storage chamber capacity. The properties of the alloys can optionally vary from the state of iron to the state of ordinary cupola iron.
На фиг. 1 и 2 чертежа изображены продольный и поперечный разрезы копильника вагранки с предлагаемым приспособлением.FIG. 1 and 2 of the drawing shows a longitudinal and transverse sections of the cupola of the cupola with the proposed device.
К копильнику 1 вагранки сбоку от выпускного отверсти 25, на одном уровне с ним, привинчиваетс к кожуху 2 вагранки металлический косой тройник 4 с отводом и крышкой 22 дл очка (гл делки ) 23 и подводом воздуха или кислорода по трубе 17. Самое обезуглероживание сплава следует производить после того, как копильник будет достаточно нагрет прежде выпущенными порци ми чугуна, так как в противном случае возможно получение недостаточноA metal oblique tee 4 with an outlet and a lid 22 for a point (head) 23 and a supply of air or oxygen through pipe 17 is screwed to the vase cup cabinet 1 at the side of the outlet 25, at the same level with it, and the air or oxygen is supplied through the pipe 17. The decarburization of the alloy follows produce after the digger is sufficiently heated with the previously released portions of the iron, because otherwise it may not be enough
перегретого дл отливки сплава. Если желают получить ковкий чугун или сталь, то после того как копильних нагрелс , расковыривают канал 16, который во все остальное врем работы вагранки остаетс закрытым глин ной пробкой , а семную крышку б (с предварительно пос 1Н енной глин ной пробкой 15 на кружок 14) быстро надевают на штыри 7; клинь ми 8 плотно прижимают крышку к фланцу 5 тройника 4 и дают по трубе 17 сжатый воздух или кислород. Стержень 11с пробкой 15 проходит через крышку б и находитс под воздейст 1ием пружины 10. Давлением газа вытекание чугуна из канала 16 приостанавливаетс ; при дальнейшем повышении давлени газ устремитс через канал 16 в копильник, где, проход сквозь слой чугуна, с одной стороны будет его обезуглероживать, как в конвертере Бессемера, а с другой стороны, благодар эксцентричности входа струи газа, будет очень перемешивать его. Опытным путем следует установить, сколькоsuperheated for casting alloy. If they want to obtain malleable iron or steel, then after the heaters are heated, they open up channel 16, which during the rest of the work of the cupola remains closed clay stopper and seed cover b (with pre-finished clay stopper 15 per circle 14) quickly put on pins 7; The wedges 8 tightly press the cover to the flange 5 of the tee 4 and give compressed air or oxygen through the pipe 17. The rod 11c by the stopper 15 passes through the cover b and is under the influence of the first spring 10. By the pressure of the gas, the outflow of cast iron from the channel 16 is suspended; as the pressure rises further, the gas rushes through channel 16 into the accumulator, where, passing through a layer of cast iron, on the one hand will decarbonize it, as in the Bessemer converter, and on the other hand, due to the eccentricity of the inlet of the gas stream, it will greatly mix it.
