摘要： Inert gas supply nozzle is mounted on a ladle body in such a manner its output-side end surface is inclined upward, relative to the bottom surface of a molten material passageway portion, in a direction toward a molten material discharge opening formed in the ladle body. Even when a portion of the molten material flows upward toward the nozzle's output-side end, that portion can be reliably prevented from entering the output-side end portion of the nozzle, by virtue of the inclined end surface. Thus, the inert gas supply nozzle can function to supply the inert gas into the molten material in a stable manner over a long period of time.

摘要： A nozzle, or porous plug, for use with molten metals is provided. The nozzle includes a connection port for connecting to a main gas line and a plurality of capillaries connected to the connection port. The capillaries are encased by refractory to protect them from the intense heat of the process. Typically, the nozzle is located at or near the bottom of a ladle and a gas is injected through the nozzle into the ladle. The gas flowing though the ladle agitates the molten metal and causes the impurities in the molten metal to form a slag. The nozzle allows the gas flow through the nozzle to be shut off during the process to allow additional slag to settle without the molten metal flowing into and plugging the capillaries.
摘要翻译：提供了一种用于熔融金属的喷嘴或多孔塞。喷嘴包括用于连接到主气体管线的连接端口和连接到连接端口的多个毛细管。毛细管被耐火材料包裹起来，以防止其过程的强烈热量。通常，喷嘴位于钢包的底部或附近，并且气体通过喷嘴注入钢包中。流经钢包的气体搅动熔融金属，导致熔融金属中的杂质形成渣。喷嘴允许气体流过喷嘴在该过程中被切断，以允许附加的炉渣沉降，而不会使熔融金属流入和堵塞毛细管。

摘要： In steel-making, there are conflicting processing requirements at different stages of the process. The method and apparatus of the invention creates different processing conditions at different stages of the process. Molten ferrous material (2) is stirred by bubbling a gas therethrough. A refractory ring (10) is first partially immersed in the molten steel within a substantially slag free portion of the surface of the molten ferrous metal to form a bounded substantially slag-free area. The molten steel is then heated by the introduction of exothermically reacting heating agents such as aluminium and oxygen through an oxygen gas line (7) and an aluminium delivery tube (9), respectively. The refractory ring (10) is then removed from the molten steel when the steel has reached a predetermined temperature and air is then excluded from the volume above the molten steel by placing a hood (16) over the ladle containing the molten steel. Sulphur is then removed from the steel.

摘要： A method of and apparatus for treating molten metal to achieve effective removal of such unwanted inclusions as gases, alkali metals, entrained solids, and the like. The method comprises continuously introducing molten metal into a container forming a trough or trough section, such as the trough provided between a melting furnace and a casting machine, providing at least one mechanically movable gas dispenser submerged within the metal in the container and introducing a gas into the metal adjacent to the gas disperser in a part of the trough forming a treatment zone such that the gas is broken into smaller bubbles by the gas dispenser and dispersed through the treatment zone. The trough or trough section is such that it exhibits a static to dynamic metal holdup of less than 50%.

摘要： An arrangement for use when treating a melt, particularly a metal melt (2) in a converter (1) with gas, for the purpose of intensifying and rendering effective the contact between gas and melt and to produce effective admixture of the gas with the melt. The arrangement includes at least one nozzle (5) which discharges into the melt (2) and which is operative to deliver the gas in the form of at least one high pressure jet. For the purpose of producing a high gas pressure of such value as to produce a finely-divided mixture of gas and melt in a jet zone (10) in the melt (2), a pressure-elevating device (9) is incorporated in the fluid line connected to the nozzle (5). The invention also relates to a method of treating a metal melt in a converter.

摘要： A refractory gas permeable injection device for introducing gas into a metallurgical vessel containing molten metal has a surface to be exposed to and progressively worn away by the molten metal during operation of the vessel. The device includes an outer body and an inner body within the outer body, at least the inner body being formed of a fireproof refractory material. A gas permeable space extends through the device in the direction of wear thereof, and the space has a plurality of different geometric shapes spaced in such direction. Upon the metallurgical vessel being emptied, and with the device still relatively hot, gas is caused to flow through the space such that the gas will create on the surface an optically recognizable image in a particular geometric shape as a function of the relative degree of wear of the device.
