摘要： PROBLEM TO BE SOLVED: To provide mold flux which is excellent in homogeneous fusibility despite high viscosity and also is excellent in uniform inflow nature.
SOLUTION: The viscosity of the mold flux at 1,300°C is made as high as 8 Poises or more so that the entrainment of the mold flux into molten steel is prevented. At the same time, in order to prevent a harmful effect resulting from a rise in viscosity, the ratio of use of a high-fusion-point raw material having a fusion point of 1,800°C or higher is limited to 10 mass% or less in total in terms of an oxide in a state of slag, so that the homogeneous fusibility is ensured. Further, the mold flux is made to have a calorific value of 200 cal/g or more by mixing an organic substance and/or a carbonaceous substance into the mold flux and is granulated so that the uniform inflow nature is ensured.

A second high-pressure water nozzle is provided which is opposite to the flame scarfing slag left on the flame scarfing surface passing through the flame scarfing nozzle, and which is arranged on a back side of the flame scarfing nozzle, extends horizontally parallel to the flame scarfing nozzle and keeps a predetermined distance from the steel slab. The second high-pressure water nozzle has a plurality of blow-out holes arranged straight with the angle θ of delay in the steel slab moving direction, and jets pressurized water from the blow-out holes to completely remove slag from the surface of the steel slab.
