Description

Technical field

[0001] The invention relates to the technical field of molten iron pretreatment, in particular to a molten iron tank slag removing system and a molten iron tank slag removing method. Background technique

[0002] Desulfurization of molten iron is a necessary part of the steelmaking process. After the desulfurization of molten iron, a large amount of slag floats on the surface of the molten iron. Fast slag removal can shorten the desulfurization cycle, gain time for other links in the steelmaking cycle, and reduce the labor of operators. Improving the cleanliness of slagging can reduce sulfur back and improve the desulfurization effect. Reducing the iron loss of desulfurization slagging can save production cost and improve efficiency. Therefore, inventing a method for rapid slag removal, which can improve the cleanliness of slag removal and reduce iron loss at the same time, has a very positive significance for improving the quality of steel products and improvin...
