摘要： Part of a melt vessel (6) is formed from a porous member (6a) which is permeable to gas and impermeable to melts (2). Alternatively, a bottomed cylindrical partitioning member (11) immersed in a melt in the melt vessel (6), or part of a circulating vessel (15) through which the melt circulates, or a dam (17) disposed in the course of circulation of the melt in the melt circulating vessel (16) is formed from the porous member. Vacuum pump is used to suck gas from the melt or gas produced by a reaction at the interface between the melt and the porous member through the porous member, to the side of that surface of the porous member which is not in contact with the melt and kept at a vacuum or at reduced pressure. Then, the pressure at the interface between the melt and the porous member is lowered, and a space which is in a vacuum or at reduced pressure can be easily created in the melt. Thus, solute ingredients of the melt nucleate easily to form gaseous substances, so that the gaseous substances are sucked into said space and removed from the melt.

摘要翻译：熔体容器（6）的一部分由可渗透气体并且不可熔化的多孔构件（6a）形成（2）。或者，浸入熔融容器（6）中的熔体中的有底圆柱形分隔件（11）或熔体循环通过的循环容器（15）的一部分，或在循环过程中设置的坝（17）熔体循环容器（16）中的熔体由多孔构件形成。真空泵用于从熔体和多孔构件之间的界面处的反应产生的熔体或气体通过多孔构件吸附到与熔体不接触的多孔构件的表面侧，保持在真空或减压下。然后，熔体与多孔构件之间的界面处的压力降低，并且可以容易地在熔体中产生处于真空或减压的空间。因此，熔体的溶质成分容易形成气态物质，使得气态物质被吸入所述空间并从熔体中除去。

摘要： A melt (2) is stored in a vessel (5), and a lower half portion of a rod-formed porous member (6) is immersed in the melt. This porous member is made of a porous material having pores which is permeable to gas and impermeable to melts, such as molten metal, molten slag, and molten matte. When this vessel is placed in a decompression container and the portion of the porous member which protrudes above a surface of the melt is put in vacuum or under reduced pressure, gases in the melt or gases produced by reactions between components of the porous member and the melt pass through pores of the porous member and are released to vacuum or depressurized atmosphere in the decompression container. Thus, gas-forming components are removed from the melt.

摘要： A melt (2) is stored in a vessel (5) placed in a decompression vessel (10). On the bottom of the vessel is arranged a bubble generator (9) made of porous bricks, and bubbles of argon gas are introduced into the melt through this bubble generator. Also a lower half section of a degassing member is immersed in the melt. This degassing member (6) has a cylindrical form with the lower end closed and the section immersed in the melt is made of a porous material permeable to gases and impermeable to melts.
With these features, a surface of molten metal can be put under reduced pressure and high content components of the melt can be removed by means of bubbling, and also solute components in the melt can be removed into bubbles of argon gas. Also, gases in the melt and gases produced by reactions between the melt and the porous material can be sucked through a wall of the degassing member into inside thereof and removed.

摘要： A melt (2) is stored in a vessel(5). A lower half of a degassing member (6) is immersed in the melt. The degassing member has a cylindrical form with the lower end closed, and the lower half section is made of a porous material which is permeable to gas and impermeable to melts as molten metal, molten slag, or molten matte. This lower half section is a partitioning member (6a). When an internal space inside the degassing member is sucked to realize vacuum or reduced pressure atmosphere, gas-producing components in the melt pass through the partition member (6a) of the degassing member, and are exhausted to inside the degassing member, thus being separated from the melt. Also, by making the degassing member rotate or move in a horizontal or vertical direction, the melt is stirred. With these features, gas-producing components in the melt can be removed at a high efficiency.

摘要： A melt flow pipe (15) is arranged penetrating a vacuum container (14). The melt flow pipe is made of a porous material having pores which allow premeation of gases but does not allow permeation of melts (2) such as molten metal, molten slag, and molten matte. And, in the wall of this melt flow pipe are buried a pipe-like member (16) wherein a cooling medium flows in a form of coil.
As the melt contact the external surface of the flow pipe and this section is exposed to a vacuum state, gases in the melt or gases generated through reactions between the melt and the porous member pass through the porous flow pipe to the internal surface side and removed. When the melts flows therein, the flow pipe is cooled by a cooling medium, so that degasification of the melt can be made continuously.
