摘要： A smelting vessel includes a plurality of heat pipes (21) positioned in a refractory lining of at least a part of the hearth (9) for cooling at least a part of the refractory lining. At least one of the heat pipes includes (a) a liquid phase of a heat transfer fluid, typically water, in a lower section of the heat pipe and (b) a vapor phase of the heat transfer fluid, typically steam, in an upper section of the heat pipe. The heat pipe also includes a vent to allow vapour phase to escape from the heat pipe to reduce the pressure or the temperature within the heat pipe when the vapour pressure or the temperature in the heat pipe exceeds a predetermined threshold pressure or temperature.

摘要： A method for producing a retort for a nitriding furnace, in which metallic workpieces are heat-treated in a pre-determined atmosphere, includes pickling at least the surfaces of the retort, which are configured to come into contact with the pre-determined atmosphere while the nitriding furnace is operating, by using a pickling agent. The pickled surfaces may then be electropolished and passivated. A retort may be produced according to this method and the retort may be used in a nitriding furnace.

摘要： A method of starting a molten bath-based process for smelting a metalliferous material is disclosed. The method includes using the heat flux of water-cooled elements in lower parts of a smelting vessel to provide an indication of molten bath temperature during at least an early part of the start-up method and adjusting injection rates of oxygen-containing gas and/or carbonaceous material into the smelting vessel to control the molten bath temperature during start-up without exceeding critical heat flux levels and tripping the start-up method.

摘要： Embodiments of the present invention comprise a refractory delta made from a refractory material having a cold-face side and a hot-face side. One or more electrode apertures are located in the refractory delta for receiving one or more electrodes. One or more cooling apertures extend from the cold-face side of the refractory material to adjacent the hot-face side of the refractory material. The one or more cooling apertures may further comprise a copper tube. A cooling system delivers a cooling liquid to the one or more cooling apertures, and the cooling liquid draws heat from the adjacent refractory material, including the hot-face side, and evaporates to allow replacement cooling liquid to further draw heat from the adjacent refractory material.

摘要： A panel cooled with a fluid, for metallurgic furnaces, includes a first chamber having a face which, in assembly conditions, is configured to face an interior of a metallurgic furnace and an opposite face in thermal contact with a face of a second chamber whose opposed face is configured to face, in assembly conditions, an external part of the metallurgic furnace. The first and second chambers are mutually independent. The first and second chambers each include an inlet and outlet of a cooling fluid. The panel has a first working configuration in which the first chamber is passed by a first cooling fluid and the second chamber is passed by a second cooling fluid different from the first cooling fluid, and a second working configuration in which the first chamber is passed by the second cooling fluid and the second chamber is passed by the first cooling fluid.

摘要： A casting system and method. The casting system can include an energy source and a hearth, which can have a tapered cavity. The tapered cavity can have a first end portion and a second end portion, and the tapered cavity can narrow between the first and second end portions. Further, the tapered cavity can have an inlet at the first end portion that defines an inlet capacity, and one or more outlets at the second end portion that define an outlet capacity. Where the cavity has a single outlet, the outlet capacity can be less than the inlet capacity. Where the cavity has multiple outlets, the combined outlet capacity can match the inlet capacity. Further, the cross-sectional area of the tapered cavity near the inlet can be similar to the cross-sectional area of the inlet.
