Abstract: PURPOSE:To restrain the sticking and the deposit of slag to the inner wall at the upper part of a free board by blowing gas containing oxygen from the inlet of an exhaust gas duct in an immersion free board and burning. CONSTITUTION:The lower part of the immersion free board is immersed into molten iron 1 in a molten iron ladle 2 to shut off the outer air, and the oxygen or oxide and a prescribed treating agent are charged into the molten iron 1 from a lance 4 at the center part of the free board 3 to execute the pretreatment. A nozzle 19 toward the free board 3 side is arranged in the inner part of the inlet part of the exhaust gas duct 18 communicated with the upper side wall of the immersion free board 3 in this device. During pretreatment, the gas exhausted to the exhaust gas duct 18 from the treated molten iron is burnt at the inlet part of the exhaust gas duct 18 by blowing the gas 20 containing the oxygen from the nozzle 19. At this time, the slag and the metal stuck to the inner wall at the upper part of the immersion free board 3 is melted and removed by the generated combustion heat.

The coils L1, L2, and L3 are coaxially arranged to be formed as a tower reactor, and a rod-shaped core K is configured to enable easy insertion and withdrawal. When the core K is inserted into the coils L1, L2, and L3, the reactance of the circuit increases to reduce the start current value. When the core K is withdrawn, the reactance of the circuit decreases to increase the start current value.  Since the start current value can be switched only merely by selecting the presence or absence of the core K in the reactor R, the need for conventional taps and complex wiring are eliminated.
