Использование: плавка чугуна в литейном производстве. Цель: снижение удельного расхода огнеупорных материалов холостой огнеупорной насадки и футеровки вагранки. Сущность изобретения: вагранка газовая содержит на подине шахты холостую огнеупорную насадку высотой 0,3 - 0,4 диаметра шахты и выносную камеру с площадью внутреннего горизонтального сечения (т.е. площадью бассейна металла), равной 0,5 - 0,8 площади сечения шахты вагранки.Usage: cast iron smelting in the foundry. Purpose: to reduce the specific consumption of refractory materials of the idle refractory nozzle and cupola lining. The inventive gas cupola contains on the bottom of the shaft a single refractory nozzle with a height of 0.3 - 0.4 shaft diameters and a remote chamber with an internal horizontal section (i.e., a metal pool area) of 0.5 - 0.8 sectional area cupola shafts.
