摘要： A rotary nozzle which is simple in construction, has no danger of leakage of molten steel and is capable of rotatably connecting a collector nozzle and a long nozzle. The rotary nozzle includes a fixed plate brick (10) attached to a base member (1) and having a sliding surface thereof formed to incline with an angle of ϑ°. A slide plate brick (18) having a sliding surface thereof formed as an inclined surface corresponding to the sliding surface of the fixed plate brick (10) is fixedly mounted, along with a collector nozzle (22), in a supporting member (12). A frame (25) vertically displaceably supports the supporting member (12) through a plurality of spring means (37) and bolts and is adapted to be driven by driving means mounted on the base member. The lower end (24) of the collector nozzle (22) is formed into a spherical shape so as to ensure its smooth connection with a long nozzle and its rotation.

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.

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 brick body for a rotary nozzle formed in a generally oval shape in plan view capable of holding the contact area of a nozzle part to improve the cause on shape of the remarkable deterioration of durability. The brick body for the rotary nozzle is characterized in that the outline thereof in plan view is formed of a first arc part (G), a second arc part (H), a third arc part (K), and a tangential line connecting the first arc part to the third arc part, and the generally oval shape with a long tangential line is changed to a generally elliptic shape by additionally providing arcs and shortening the tangential line. Since the straight line parts of the outline of the brick body in plan view are shortened and formed in arcs to form the brick body in a generally elliptic inflated shape, the contact area can be held even if a sliding plate brick is rotated to fully open and the possibility of leaking of molten steel can be eliminated.
