压力浇注炉是铸造工业中槽式炉的又一个应用。炉子设计成一个压力容器,其出入口在炉桶的底部,呈一茶壶形。确保无渣浇注,见下图。它是利用惰性气体或压缩空气充入容器,迫使金属进入浇注道。 Pressure pouring furnace is another application of the trough furnace in the foundry industry. The furnace is designed as a pressure vessel, with its entrance at the bottom of the hearth, in the shape of a teapot. Make sure no slag is poured, see below. It is filled with inert gas or compressed air into the container, forcing the metal into the sprue.
