Abstract
PURPOSE: To let the protection of inside wall refractories be effected readily and surely by mounting a removable box-shape inside wall protector to the inner side of the inside wall refractories of the molten steel vessel and blowing inert gas from the bottom.
CONSTITUTION: A refractory lining inside wall protector 5 made of heat-insulation boards is fromed in the box shape removable from the inside wall, on the inner side of the refractory lining of the perma bricks 3 and ware bricks 4 of the vessel for molten steel such as ladle and tundish. A groove 11 for fitting and setting an inert gas lead-in pipe 10 is provided on the back side of the side wall board 9 of this protector and the back of its bottom wall board 6 and a hole 7 is pierced in the bottom wall board 6, into the former of which a porous plug 8 is mounted and is connected to the inert gas lead-in pipe 10. This inside wall protector 5 is set in the vessel 1, after which molten steel is put therein and inert gas is introduced from the bottom, whereby nonmetallic incusions, etc. are removed and the molten steel is refined. At this time, the damages of the refractory linings such as ware bricks 4, perma bricks 3 become extremely less.
