In practice, it is necessary to remove the layers of sediments because the sedimentse may cause short circuit in the electrical furnace resulting in hampering the production. An effective approach to solve this problem is to fragment the sediments by blasting, because of the complicated compositions and the extreme hardness of the slag sediments. The blasting-holes are created by means of oxygen blowing, and the optimum blasting parmeters for this special smelting furnace are calculated. The effects after blasting show that the method for removing the sediments by blasting is feasible and appropriate.
