    Abstract: The invention relates to a method for regulating the flow rate and for slowing down melt streams through magnetic fields in the tapping of metallurgical containers such as blast furnaces and melt furnaces. The method is characterized in that the melt stream is routed in a closed routing element using at least two magnetic fields disposed in series one after the other in the flow direction of the melt, said magnetic fields having a constant polarity opposite to one another, in such a way that the magnetic field lines transversally penetrate the melt flow across the entire cross section thereof and such that opposite voltages are induced in the melt stream by the magnetic fields, there being at least three eddy current fields produced thereby in the melt stream that are disposed axially one after the other, and that due to the interactions between the magnetic fields and the eddy currents forces are generated that can be used to reduce the flow rate of the melt stream.

    Abstract translation: 本发明涉及一种用于调节流速和通过冶金容器如高炉和熔炉中的磁场减少熔体流的方法。 该方法的特征在于，使用至少两个在熔体的流动方向上一个接一个地串联设置的磁场，将熔体流布置在封闭的路由元件中，所述磁场具有彼此相反的恒定极性， 这样一种方式使得磁场线横跨其整个横截面的熔体流动，并且使得在熔体流中由磁场引起相反的电压，因此在熔体流中产生至少三个涡流场， 轴向地一个接一个地布置，并且由于磁场和涡流之间的相互作用产生的力被产生，其可用于降低熔体流的流速。

    Abstract: A taphole structure of a melting furnace includes: a sleeve made of a fire-resistant brick, which is disposed inside a tapping hole provided in a furnace wall brick; and a ramming material which fills a gap between the sleeve and the tapping hole for fixing the sleeve. In addition, a repair method of the taphole which has expanded due to wear of a first ramming material during tapping, includes: forming a dismantled surface having a straight line shape by dismantling and removing a worn portion of the first ramming material in a straight line from an outer surface side toward an inner surface side of a furnace wall; and then filling a second ramming material into a gap between the dismantled surface having the straight line shape and a first sleeve for sealing.

    Abstract: An automatic dross processing system has a pivotably-mounted reaction vessel and a vertically movable motor and impeller. A microprocessor controls the operation of the motor and a series of actuators that move the motor vertically, move a probe that removes a plug to drain collected metal from the reaction vessel, and move the reaction vessel between a loading-and-processing position and a dumping position. The microprocessor coordinates the actions of these elements to complete a dross processing cycle to recover metal from a dross without requiring the attention of an operator throughout the process. The reaction vessel can have an inner shell and an outer shell that are bolted together with a gap therebetween to accommodate insulation, which can include a felt overlying one or more pieces of rigid material. A drain tube can be attached to the inner shell by an accordion-like structure to reduce thermal stresses in service.

    Abstract: A sliding nozzle unit in which a face pressure load is released by inserting a cotter into a press member provided in an open close metal frame and sliding the cotter on an inclination block provided on the side face of a sliding metal frame thereby flexing a resilient body through the press member. The inclination block is spaced apart from the nozzle hole of a sliding plate on the longitudinal side face of the sliding metal frame. Inclining face of the inclination block is formed to become lower toward the direction for fully closing the nozzle hole and a stop member is provided on the longitudinal side face of the sliding metal frame, in the vicinity of nozzle hole of the sliding plate, so that the nozzle hole is not fully opened under a state where the cotter is inserted into the press member. Alternatively, the inclination block may be disposed closely to the nozzle hole in the longitudinal side face of the sliding metal frame, the inclining face of the inclination block is formed to become lower toward the direction for fully opening the nozzle hole and a stop member may be provided to be closer to the full close side than the inclination block, and on the longitudinal side face of the sliding metal frame so that the nozzle hole is not fully opened under a state where the cotter is inserted into the press member.
