    • A porous layer consisting of sintered material containing metal powder or ceramics powder is provided as the inner surface of a mold for use in continuous metal casting, and a shielding plate is provided on the outside of this porous layer. A gas is supplied in a gap portion formed between the porous layer and the shielding plate and the gas is spouted out from the porous portions in the porous layer into the inside of the mold, thereby forming a gas film between the inner surface of the mold and the molten metal. Electromagnetic coils are interposed between a stiffening plate and sandwiching frames around the mold and hanger frames supporting them. An annular cylindrical partition wall surrounding a nozzle is provided between the mold and a tundish, and a water-cooled reflecting plate having an annular downward reflecting surface is also provided therebetween.
    • 提供由含有金属粉末或陶瓷粉末的烧结材料构成的多孔层作为用于连续金属铸造的模具的内表面,并且在该多孔层的外侧设置有屏蔽板。 在形成于多孔层和屏蔽板之间的间隙部分中供给气体,并且将多孔层中的多孔部分中的气体喷射到模具的内部,从而在模具的内表面之间形成气膜 和熔融金属。 电磁线圈介于加强板和围绕模具的夹持框架和支撑它们的悬挂框架之间。 在模具和中间包之间设置有围绕喷嘴的环形圆筒形分隔壁,并且还设置有具有环形向下反射表面的水冷反射板。
