<p>An arc metallurgic furnace slagging door comprising a lower slag removing-pushing movable panel (16) and a top movable panel (18) which can be opened to carry out remarks and interventions on molten metal, characterized in that: said top movable panel (18) and said underlying lower movable panel (16) are placed in front of a short tunnel, giving access to the melting pot placed in front of the slagging door for closing said short tunnel; the top panel (18) of the slagging door is slightly inclined outwardly and it is suitable to move outwardly in respect to the furnace and up-wardly, substantially keeping this inclination in respect to the furnace wall, and the lower panel (16) of the slagging door is apt to carry out movements similar to those of a dredger, i.e. partial rising and partial lowering, partial advancing into the furnace and partial backing out of the furnace for both removing the slag present in the furnace melting pot, and pushing the various material inside the furnace.</p> |
