Abstract
PURPOSE: To achieve the saving of repair cost and the improvement of steel material quality by removing the slag deposited at the inflammable gas spouting port of the scarf nozzle and its vicinity by spouting hihg-pressure inert gas from the inflammable gas spouting hole.
CONSTITUTION: During scarfing work, the shut-off valves 6, 8 of an inflammable gas, e.g., propane gas pipeline 4 and the solenoid valve 17 of a release pipeline 16 are held open and the solenoid valves 13, 14 of an inert gas, e.g., N2 gas pipeline 11 and the solenoid valve 9 of a release pipeline 8 are held closed and therefore only the propane gas is supplied to a scarf nozzle 1 and is injected to the slag surface. Several seconds after the ending of the scarfing, the shut-off valves 6, 7 and solenoid valve 17 are put in the close position and the solenoid valves 13, 14, 9 in the open position to supply only the N2 gas to the nozzle 1 and be spouted through the injection orifice thereby blowing away the slag deposited thereon without any oxidation reaction. The respective gases leaking from the respective valves are released from release pipes 8, 16 respectively.
