Internal placed pouring-nozzle for steel ladle

The utility model relates to an internal placed pouring-nozzle for a steel ladle. The utility model is composed of a seat brick and a water nozzle. The lower part of an inner hole of the seat brick forms a cross cutting cone. The upper end is provided with an inverted conical opening which has a coaxial line with the seat brick. The outer surface of the water nozzle forms a cross cutting cone which is the same as the conical angle of the cross cutting cone at the lower part of the inner hole of the seat brick. The inner hole is a cylindrical hole which has a coaxial line with the cross cutting cone of the outer surface. The water nozzle is arranged in the seat brick. A section of cylinder is arranged between the inverted conical opening in the seat brick and the cross cutting cone at the lower part, the cylinder has a coaxial line with the cross cutting cone at the lower part, and the diameter of the cylinder is equal to the diameter of the inner hole of the water nozzle. The upper end surface of the water nozzle contacts a table shoulder surface of the cross cutting cone at the lower part of the seat brick. The pouring-nozzle leads the opening rate of filler, the service life of the water nozzle and the production security to be enhanced.
