Abstract：Abstract：The main reasons for the low inclusion removal rat of the strip gas curtain were analyzed. A dispersion type annular gas curtain and argon blowing intelligent control technology were developed，and the molten steel flowing to the tundish nozzle was completely washed by the gas curtain,ths eliminating the triangular bubble blind area of the strip-shaped gas curtain,and theinvention solves the key technical problem of slag entrapment on the steel liquid surface in the tundish , breaks through the key technical bottleneck of low and unstable inclusion removal rate of the strip gas curtain, and improves the inclusion removal rate.
