| description | PROBLEM TO BE SOLVED: To provide a method for performing the efficient and sure removal of cut-off slag and a device for performing this method with which even in the case of being a vertical type continuous casting, the sticking of the cut-off slag can sufficiently be removed and it does not become disadvantageous to the following processing process of a steel material, without adding a special means, such as a baffle plate. SOLUTION: The method for removing the cut-off slag, is performed as the followings, at cutting off time with universal gas, especially, in the case of gas-cutting a cast slab (steel slab) to be cut off with the vertical type continuous casting, for removing the cut-off slag stuck to the side surface of the cut-off surface, a slag removal nozzle for spouting the mixture of high pressure oxygen and low pressure water from the tip end part, is set at a position faced to the cut-off slag, and a blowing pipe holding the nozzle is automatically moved at a fixed speed while spouting this mixed fluid toward the cut-off slag so as to remove the cut-off slag.
