摘要： A direct-current arc furnace for producing steel has a smelting vessel with electrodes, tapping openings for the molten mass and slag, and a device for a direct removal of exhaust gases. The smelting vessel is extended upwardly by a central shaft for introducing melt-down material into the vessel. The extension of the central shaft forms a melt-down material column. A shaft suction device is provided as an extension of the shaft for removal of the exhaust gases during the smelting process. Adjacent to the shaft openings are provided in the upper part of the smelting vessel for receiving a vessel suction device for dust and/or gases resulting during the charging process of the melt-down material. The shaft suction device and the vessel suction device are connected to a common device and switching elements are provided for actuating only one suction device and/or adjusting a combination of the exhaust gas flows dependent on the charging and smelting process.

摘要： A method and apparatus for producing metal slabs in which especially a metal strip of steel is conducted through a bottom entry device of a vessel which is filled with molten metal, particularly steel, and, after the molten metal has crystallized onto the metal slab, the coated metal slab, particularly the coated metal strip, is pulled off above the vessel, wherein the crystallization carrier is conducted though the bottom entry device of the vessel which provides a clear opening width between the core strip and the entry device. Controlled cooling is carried out in the bottom area of the vessel containing the molten metal. The temperature of the molten metal at the nozzle exit of the bottom entry device is adjusted to be greater than the liquidus temperature of the molten metal. A meniscus in the pure melt phase is formed at the nozzle exit at the bottom entry device. A distance exists between the meniscus of the molten metal at the nozzle exit and the begin of the solidification. The heat removal in the area of the bottom entry device is controlled in dependence on the strip speed, bath temperature and gap width in such a way that the meniscus is formed freely and stationary at the nozzle exit.

摘要： Molten steel is poured into a water cooled continuous casting mold in which the steel solidifies partially with the formation of a strand having a length and a peripheral shell. The strand has a cross-sectional surface area with one of a round shape, an oval shape and a polygonal shape having more than four sides. Additionally, the strand has a minimum circumference of 200 mm. The cross-sectional surface area of the strand leaving the mold is then reduced using rolls before the strand fully solidifies. The reducing includes deforming the strand into a polygonal shape having at least four corners while maintaining the circumference as well as the length of the strand at the peripheral shell constant.

The outer wall (12) of the pouring spout (10) is shaped in its longitudinal-side region (17) facing the longitudinal mold side (21) so that is has a substantially constant distance (d) relative to the longitudinal sides (21) of the mold, regardless of the immersion depth of the pouring spout into the melt in the continuous casting mold. In addition, the outer wall of the pouring spout, in its transverse-side regions (16) facing the transverse mold sides (22), has form elements that oppose a minimum resistance to the horizontal flow of the molten steel and the casting powder floating thereon.
