Refractories used for ladles are generally ladles and refining refractories, furnace refractories, converter refractories, tundish refractories, blast furnace refractories, etc. Specific products are ladle air permeable bricks , furnace cover, tundish slag retaining wall, castable, ramming materials, etc. The purpose of ladle gas permeable bricks used by steelmaking factories is to remove harmful gases and impurities, adjust the composition, so as to complete the basic tasks of oxygen supply, slagging, stirring, heating and other steelmaking. In addition to ladle permeable bricks , refractories for ladle and refining are magnesia-carbon bricks , nozzle seat bricks, slide-board bricks, spinel castables, magnesia-chrome bricks, sliding nozzles, etc. The materials are magnesia-carbon, high alumina, spinel, alumina-carbon, etc. The refractories used in electric furnace are mainly the furnace cover, bottom air permeable brick, side wall spraying material, tapping fill
