| The invention relates to a method for regulating the flow rate and for slowing down non-ferromagnetic, electrically conducting liquids and melt streams through magnetic fields, in particular 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 one stationary magnetic field with a constant polarity, at least one stationary magnetic alternating field or using a multi-poled magnetic travelling field, in such a way that the magnetic field lines transversally penetrate the melt flow across the entire cross section thereof and such that a voltage is induced in the melt stream by the magnetic fields, there being eddy currents induced thereby in the melt stream that are disposed radially and axially when a stationary magnetic field of constant polarity is used and that are disposed axially when a stationary alternating magnetic field or electromagnetic travelling field is used, and that due to the interactions between the magnetic fields and the eddy currents forces are generated that can affect the flow rate of the melt stream. | ||||||

| The embodiments of the invention relate to a tap hole plug gun for metallurgical furnaces, having a pressure cylinder for receiving the plugging compound, which has a closable filling opening for the plugging compound, and having a plugging piston for pressing the plugging compound out from a mouthpiece of the pressure cylinder pressed against the tap hole of a furnace. The pivotable safety flap for closing the filling opening of the pressure cylinder for the plugging compound is equipped with a stop, which is pivoted into the cylinder chamber of the pressure cylinder upon opening of the flap to decelerate an unintentional forward stroke of the plugging piston for pre-compression and expulsion of the plugging compound, and is pivoted out of the cylinder chamber upon closing of the safety flap. | ||||||

| A mud gun cap is provided. The mud gun cap includes a flame resistant outer face, a ring and a mounting device wherein the mud gun cap connects to a mud gun nozzle to protect the mud gun nozzle from deterioration because of contact with molten iron and slag. The mud gun cap also prevents, or at least reduces the amount of, mud falling out of the nozzle while the mud gun nozzle is rotated into operation position. | ||||||

| An apparatus for centering a tap drill is provided herein. The device includes a body made of a refractory material that has a tapered shape and a connector secured to body configured to permit connection of the body to a tap drill bit. In addition, a method of operating a blast furnace is provided herein. The method includes providing a blast furnace plug having a refractory body having a tapered configuration. Securing the blast furnace plug to a tap drill bit. Aligning the blast furnace plug with a tap hole plugged with mud, and inserting the blast furnace plug into the mud to create an indentation in the mud having a tapered configuration. Removing the blast furnace plug from the tap drill bit, aligning the tap drill bit with the indentation and tapping the blast furnace. | ||||||

| 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. | ||||||

| 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. | ||||||
