Abstract
Procedure for installing a removable refractory plug containing nozzles, and a metal bottom plate at the bottom of a container for refining molten metal, characterized in that it comprises, the gases of placing said plug at the bottom of said container with a radial clearance of the order from 6mm to 127mm. between said stopper and the existing lining of said container; attaching said plate to said container; and filling the space between said stopper and said existing lining in the container with a monolithic refractory mixture composed of approximately 90 to 98% of a mixture of 85 to 95% of magnesite having a MgO content of the order of 90 98%, a grain porosity of less than 12% of its total volume, and a silica content of less than 3%; about 1 to 5% fine carbon, with a particle size of 100 meshes; approximately 2 to 8% solid pitch with a -100 mesh particle size and a ring and ball softening point of between 99ºC and 149ºC; and from about 1 to 8% of a water-soluble chemical binding agent chosen from the group consisting of chromic acid, sodium silicate, magnesium chloride, magnesium sulfate, and boric acid; and 2 to 10% water.
