EQUIPMENT AND METHOD FOR ARC MELTING OF COLD PIG IRON SOURCE

摘要

An arc melting equipment for cold pig iron source which does not require a transfer and feed device for cold pig iron source to a melting furnace, enables preheating of the next charge of cold pig iron source, and provides an extremely high efficiency which cannot be achieved by the conventional melting equipment in which cold pig iron source is preheated utilizing exhaust gas, comprising a melting furnace for melting cold pig iron source, a preheat shaft which is connected directly to the upper part of the furnace on one side and introduces waste gas generated in the melting furnace so as to preheat cold pig iron source, an arc electrode for melting cold pig iron source in the melting furnace, a cold pig iron source feed device which feeds cold pig iron source to the preheat shaft so that a state that cold pig iron source is present continuously in the melting furnace and the preheat shaft can be maintained, a tapping part which is installed projectedly on the melting furnace and provided with a tap hole, and a tilting means which tilts the melting furnace to the tapping part side, the tapping part being provided in a direction crossing at right angle the direction in which cold pig iron source is fed to the melting furnace, and a separation part being provided between a position where the preheat shaft is provided and a position where the tapping part is provided in the melting furnace so as to prevent cold pig iron source from flowing out to the tap hole side.
