APPARATUS FOR DECREASING OUTFLOW OF SLAG WITH PREVENTING VORTEX OF SLAG

摘要

The present invention relates to a slag outflow reduction device for preventing vortex, and more particularly, to a vortex prevention slag outflow reduction device for minimizing slag outflow by preventing vortex formed in slag during molten steel in the converter. will be.;To this end, the slag vortex preventing portion (8) consisting of a pair of vortex preventing plates (9, 9 '), and a vortex preventing plate fixing base (10) formed with a connecting rod through hole (11) in the center while fixing it, and vortex Having a connecting rod 12 to be fixed to penetrate through the connecting rod through hole 11 formed in the prevention plate fixing base 10, the molten steel 4 is discharged and the slag 3 is prevented from being disposed at the exit hole 6. Provides a vortex prevention slag outflow reduction device, characterized in that consisting of a dart portion (2).;As described above, the slag outflow reduction device for preventing vortex according to the present invention is introduced into the upper part of the exit port from the middle of the tap during the steel tapping in the converter to suppress the slag vortex formation, thereby minimizing the slag outflow during tapping, thereby minimizing the slag outflow and the lifting amount Increasing the pressure, and there is an effect to prevent the nozzle clogging phenomenon during continuous casting.
