    Abstract: A process to improve electric arc furnace steelmaking. The efficiency increase is due to the metal-slag stirring that is produced by bottom gas injection through gas permeable ceramic elements. The permeable elements are not penetrated by the liquid metal, which does not stop the gas flow.The process is carried out in combination with a furnace charging door stopper device. The device avoids liquid ejections through the furnace charging door during the injection periods. The electric arc furnace steelmaking generalized practices are more effective when the molten metal is being stirred by gas injection, by increasing the metal-slag and the slag-atmosphere interphase area. When the stirring gas is natural gas, the process conditions, oxidizing or reducing, are reinforced according to the slag in the bath.

    Abstract translation: 改善电弧炉炼钢的工艺。 效率提高是由于通过透气陶瓷元件的底部气体注入产生的金属 - 炉渣搅拌。 可渗透元件不被液态金属渗入，不会阻止气体流动。 该过程与炉充电门停止装置结合进行。 该装置在注射期间避免通过炉充电门的液体喷射。 通过增加金属渣和渣 - 气相间区域，通过气体注入搅拌熔融金属时，电弧炉炼钢的广义实践更为有效。 当搅拌气体是天然气时，根据浴中的炉渣来加强工艺条件，氧化或还原。

    Abstract: In a process for melting down sponge metal (11) in an electric-arc furnace (1) having at least one electrode (6), the sponge metal (11) is introduced into the electric-arc furnace (1) under formation of at least one sponge metal jet (15) which in the immediate vicinity of an electrode (6) hits the bath level (16) present in the electric-arc furnace (1), and for decarburization and/or intermixing the bath and/or charging energy oxygen is blown into the melt (7). For a CO post-combustion, in addition to the oxygen introduced for decarburization and/or intermixing the bath and/or charging energy into the melt at least one jet (14) of oxygen or one jet (14) of an oxygen-containing gas is blown into the electric-arc furnace (1) at a low rate, which jet hits the bath level (16) in the region of the point of incidence of the sponge metal jet (15), which preferably is conveyed into the electric-arc furnace (1) by gravitation alone, and/or immediately adjacent to the point of incidence of the sponge metal jet (15) and which jet in the region or vicinity of that point of incidence, on the side facing the electrode(s) (6) of the electric-arc furnace (1), is shielded by the sponge metal jet (15) relative to the electrode(s) (6) in the form of a protective shield.

    Abstract: The invention concerns a process for fitting a gas-injecting nozzle in the wall of an installation. The process is characterized in that an external supporting surface (11) whose shape matches the so-called internal supporting surface (12) of the passage (6) provided in the bedding brick is associated with the nozzle (2); the nozzle is placed opposite the passage (6) in the bedding brick: the nozzle (2) is moved in axial translation so as to adjust the position thereof along the longitudinal axis of the passage and move the front face of the nozzle into a desired initial position; the nozzle is locked in this desired initial position; and, at least periodically, the nozzle is inserted further forwards into the passage in the bedding brick in order to compensate the wear in the front face of the nozzle. The invention can be used to prevent clogging, such as in a cement producing plant.

    Abstract: A plug for a furnace header having a pair of pipe continuations formed within the furnace header. Each pipe continuation terminates at an opening having a conical interior surface and is connected to the other by a pipe extending between them. The plug has a conical portion for engaging the conical interior surface on the furnace header to seal off the pipe. The plug also includes a portion having a generally concave arcuate surface forming a 90.degree. bend in a plane that bisects both of the pipe continuations and whose edges conform to the internal dimensions of the furnace header adjacent the opening. A locking mechanism secures the plug within the furnace header.
