Abstract:
This arc furnace is provided with a furnace main body (1) in which raw material (S) to be dissolved is charged, a furnace cover (4) which closes a top opening in the furnace main body (1), arc electrodes (5) which are inserted from the top of the furnace cover (4) into the furnace main body (1) and which, by being electrified, form an arc and dissolve the raw material, and a discharge port (6) which discharges discharge gas in the furnace main body (1). The arc electrodes (5) are arranged such that in the horizontal plane of the furnace main body (1), the center of arc heating is eccentric from the center of the furnace main body towards one side. The discharge port (6) is in the side wall of the furnace main body (1) opposite the eccentricity direction of the arc electrodes (5) and is provided at a height position in the range where raw material (S) is present, and the discharge gas generated by arc heat from the arc electrodes (5) is discharged from the discharge port (6) through the raw material (S) charged in the furnace main body (1).
