EQUIPMENT AND METHOD FOR ARC MELTING OF COLD PIG IRON SOURCE

摘要

The present invention provides an arc-melting apparatus, with extremely high efficiency of preheating scraps by making use of an exhausting gas, which cannot be obtained by the conventional apparatus, which needs for no device to carry and supply an iron source to a melting chamber, and which makes it possible to preheat for next charge. The arc-melting apparatus has a melting furnace which melts scraps, a preheating shaft connected directly to an upper part of one side of the melting furnace, an arc electrode for melting scraps in the melting furnace, a bucket for supplying scraps to the preheat shaft so as to maintain a condition that the scraps is kept existing continuously in the melting furnace and the preheating shaft, a tapping portion having a tapping hole, being projected outward from the melting furnace and a tilting device for tilting the melting furnace on a side of the tapping portion. The tapping portion is arranged at an orthogonal direction toward a direction of a supplied cold iron source. The preheating shaft of the melting furnace and the tapping portion has a distance between the mutual part, so that scraps do not flow out on a the tapping hole side.
