The invention discloses an automatic
slag splashing control method and
system for a converter, and belongs to the technical field of converter
slag splashing furnace protection. The control method comprises the steps that firstly, final
slag conditions are classified according to the end point
oxygen content, the end point carbon content and the residual
manganese yield range in
molten steel; secondly, according to different final slag conditions, slag adjusting materials with the corresponding weights are selectively added into the converter to adjust the
viscosity of the slag, and the content of
magnesium oxide in the final slag is made to be 10%-15%; and thirdly, corresponding slag splashing gun position curves are selected according to different final slag conditions, and the
control system is used for carrying out automatic slag splashing operation. The automatic slag splashing control method and
system have the beneficial effects that the slag adjusting materials with corresponding weights are added according to the different final slag conditions for slag adjusting, the corresponding slag splashing gun positions are automatically selected, the automatic slag splashing operation is completed, and the slag splashing operation is standardized. The labor intensity of workers is lowered, the slag splashing time is shortened, the
nitrogen consumption is reduced, and the furnace profile can be more stable to maintain.
