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: A sealing plug 1, consisting of fireproof material 10 located between the upper shaping plate 19 and the lower shaping plate 20, is used to seal the tap hole 3 of a tiltable converter 2. Said fireproof material 10 consists of bonding clay, water, oil and other constituents, particularly of 10-30% by weight hollow glass balls made of “foam glass” produced from recovered glass which have a rough surface suitable for binding large volumes of moisture. The sealing plug 1 thus retains the necessary stability even over longer periods and can thus be shaped in the tap hole 3 so that it is arrested against the wall 28, even after longer periods of storage. The hollow glass balls 11, 12, 13, 14 also entail a significant reduction in the weight of the entire sealing plug 1.

Abstract: The present invention provides a method of high efficient slag scooping-up from liquid iron and a device for implementing said method. The two wings of slag rake mounted to the front end of cantilever descend side by side until beneath the surface of the liquid iron at a certain depth. The two rakes make swing movement respectively along the surface of liquid iron. When gradually moving close to each other in the course of swing movement, they get put together and clamp the solid slag. Then, driven by the cantilever, the two slag rakes which clamp the sold slag are brought to ascend until above the surface at a certain height. Finally they leave the space over the ladle and discharge the slag. The deslagging rate can reach over 90%. It just takes less than 3 minutes for the whole process of slagging-off. Additionally, the iron carried away in the process of slagging-off could be greatly reduced. The iron loss rate can be strictly controlled within 0.1%.
