Abstract
PURPOSE: To reduce the cost of equipment and to attain the elimination or reduction of labor sharply, by equipping the annexing meterial throwing opening and inactive gas blwing nozzle etc. in main body of furnace and carrying out degassing and component regulation at the process of flowing and passing in the furnace.
CONSTITUTION: Molten steel is stirred by the gas blown from the inactive gas blowing nozzle 39 equipped on the middle of the rising runner 2 and vacuum degassing reaction is carried out and then, is flowed in the stirring chamber 4. Alloy and desulfurizing agent etc., are thrown from the hopper 9, 11 according to the data of temperature measuring sampling apparatus 30, 37. Necessary inactive gas is blown from the inactive gas blowing nozzle 14. Slag-metal reaction and vacuum degassing, are advanced in the killing chamber 5. The slag is checked by the obstruction wall 16 and is discharged from the discharge opening 20. Alloy is added and inactive gas is blown to the molten steel passed through under the wall 16 and flowed in strirring chamber 6. Heating of the molten steel flowed in the discharge chamber 8, is carried out by throwing cooling material from the cooling material hopper 40 or heating by the heating apparatus 41 and the above molten steel is supplied from the sliding nozzle 44 to the casting apparatus 45 after regulating the temperature lastly.
