    • A hydraulic cement, such as portland cement, is produced by filling a furnace shell with the desired cement in a powdered condition. By the application of intense heat to the filling a skull is developed that lines an upwardly opening cavity. The heat, which may be supplied by electric arcs, is continued within the skull to maintain a pool of melt that has the same chemical composition as the skull and therefore does not react with the skull. Feed materials are introduced into the melt, and these materials are suitably proportioned to chemically combine within the melt without changing the chemical composition of the melt. The melt is drawn off through a tap hole and cooled to provide the desired cement.
    • 水泥水泥,如波特兰水泥,是通过在粉末状态下用所需的水泥填充炉壳来生产的。 通过施加强烈的热量来填充颅骨,开发出向上开口的腔。 可以通过电弧供应的热在颅骨内继续保持与颅骨具有相同化学成分的熔体池,因此不与头骨反应。 将进料材料引入熔体中,并且这些材料适当地成比例地在熔体内化学结合而不改变熔体的化学组成。 将熔体通过抽头孔抽出并冷却以提供所需的水泥。
