Abstract

PURPOSE: To make the transportation of molten slag by ladle etc. useless and to enable to carry out the elimination or reduction of labor and also, to make the apparatus small zize, by throwing alloy or slag making agent and carrying out degassing and component regulation stirring with inactive gas, after regulating flowing quantity of molten metal and pouring in transverse cylindrical furnace connected with the vacuum exhausting apparatus.
CONSTITUTION: Discharged molten steel from the electric furnace 46 is poured in the transverse cylindrical furnace 1 connected with the vacuum exhausting apparatus (omitted to shown in the figure) through the exhaust opening 34 from the discharge opening 38 of the receiver 35 through the flowing quantity control valve 39 and is flowed toward downstream side. Each alloy and slag making agent, such as desulfurizing agent etc., is thrown from each hopper 10.12 in the stirring chamber 4 corresponding to the component analysis value of the temperature measuring sampling apparatus 30.37 and inactive gas is blown from the blow opening 15. The molten metal is stirred vigorously and the component regulation is carried out by vacuum degassing reaction and slag- metal reaction and then, the above both reactions are advanced settling in the killing chamber 5. Produced slag is discharged outside from the discharge opening 20 watched by the level gauge 32, because the above slag is checked by the obstruction wall 17.
