AI Technical Summary
In existing technologies, the recycling of refining slag and coking dust has problems of resource waste and environmental pollution. Furthermore, when hot refining slag is poured into the ladle, it is easy to clog the permeable bricks and the ladle drain, affecting production efficiency.
Before pouring in the hot refining slag, limestone is added to the permeable bricks of the empty ladle and the upper surface of the ladle drain to isolate the hot refining slag from the bottom of the ladle. Then, coking environment dust is added to increase the temperature of the ladle refractory and refining slag. The heat of the hot refining slag is used to generate lime, which improves permeability and enhances the slag washing effect.
It effectively avoids clogging of the permeable bricks and ladle drain, increases the temperature of the ladle refractory and refining slag, enhances the slag washing effect, reduces the temperature drop of molten steel and refining time, and improves the desulfurization and inclusion removal effects.
