摘要:
A method for tapping of steel from a steelmaking furnace to a receiving vessel comprising the steps of providing a steelmaking furnace comprising a tapping hole, and means for angular positioning of the furnace to vary the depth of molten steel and slag contained in the furnace above the tapping hole; determining a guidance profile for the tapping of the furnace, the guidance profile including the parameters of minimum tapping angle, maximum tapping angle, and time of rotation from the minimum tapping angle to the maximum tapping angle; performing an initial angular rotation of the furnace from an initial position to the minimum tapping angle; beginning the transfer of molten steel from the furnace through the tapping hole to a receiving vessel; rotating the furnace to the maximum tapping angle in accordance with the guidance profile; and ceasing the flow of molten steel through the tapping hole.
