METHOD AND MELT CHANNELS FOR INTERRUPTING AND RESTORING THE MELT STREAM OF IRON AND METAL MELTS IN TAP HOLE CHANNELS OF BLAST FURNACES AND DRAINAGE CHANNELS OF MELT FURNACES

摘要

1. A method for interrupting and restoring the molten iron flow and other metals in the channels, in particular blast furnace exhaust channels and waste channels smelting furnace, characterized in that the melt stream in the channel passes to a solid state under the influence of cooling, in which the melt flow is interrupted after complete release of the blast furnace and the solidified melt is melted with reduced melt flow by heating the renewal metal tapping from the blast furnace. ! 2. A method according to claim 1, characterized in that under the action of heat in the exhaust path of the blast furnace or melter drains sealing the channel material starts to melt, so that all the material together with the closure stopper of the solidified extruded out of the channel under the action of internal pressure blast or melting oven. ! 3. A method according to claim 1 or 2, characterized in that, before solidification of the melt in the outlet channel, its outlet is closed. ! 4. A method according to claim 1, characterized in that before the melt solidifies in the flow channel of the melt stream acts, at least one magnetic field with constant polarity, or at least one alternating magnetic field, so that a melt flow induced voltage, resulting in occurrence of eddy currents as a result of interaction between the magnetic field and the eddy currents give rise to forces whose direction is opposite to the direction of melt flow and as a result of which the melt flow rate decreases yl melt flow stops. ! 5. A method of influencing the flow the molten iron and other metals in the Kan
