In the production of ferroalloys, clay bricks are used to build the furnace walls and lining at the exposed parts of the ore heating furnace. The outer lining of the furnace walls and bottom, which serve as insulation and thermal insulation, or the lining of the molten iron ladle, is used for building.
Carbon bricks are mainly used to build the furnace walls, bottom, and below the blast furnace tuyere of the non exposed air part of the submerged arc furnace, as well as the furnace hearth and tapping channel. Due to the high conductivity of carbon bricks, when using carbon brick furnace lining, the electrodes are easy to lift up, and the height of furnace wall carbon bricks and the thickness of furnace bottom carbon bricks can be appropriately reduced.
High alumina bricks are used for lining the iron outlet, blast furnace shaft, and hearth of ore hot furnaces, and can also be used for lining the molten iron ladle.
Magnesium bricks are used to build the inner lining of electric arc furnace walls, furnace bottoms, and medium and low carbon manganese iron ladle. Use magnesium aluminum bricks or magnesium chromium bricks instead of magnesium bricks to build furnace items.
The refractory temperature of metallurgical magnesia is very high. Therefore, in the production of ironworks, magnesia is often used to tie the furnace bottom, make or repair furnace walls and bottom, and can also be used as a material for blocking holes or making knotting ingot molds.
