Nano-carbon low-carbon magnesia carbon brick for ladle slag line and preparation method
The invention discloses a nano-carbon low-carbon magnesia-carbon brick for ladle slag lines and a preparation method, wherein the magnesia-carbon brick comprises fused magnesia with five particle sizes, dispersible nano-carbon and an antioxidant, and through coating of nano-carbon films on the surfaces of fused magnesia particles with different particle sizes and application of the dispersible nano-carbon, the nano-carbon low-carbon magnesia-carbon brick can be used for ladle slag lines. By utilizing the characteristics that the nano carbon film and the dispersible nano carbon are mainly amorphous carbon, contain a small amount of graphite young crystals, can be infiltrated by a solvent and the like, infiltration and adsorption of the nano carbon film and the dispersible nano carbon to anorganic binding agent are improved, and uniform dispersion of the nano carbon in the magnesia carbon brick is realized; in addition, the size of carbon particles in the magnesia carbon brick is greatly reduced by controlling the sizes of the nanocarbon film and the dispersible nanocarbon with the thickness of 20-200 nanometers, the contact frequency of a refractory raw material of the magnesia carbon brick and the carbon particles is remarkably improved, the performance of the carbon particles is exerted under the condition of low carbon content, and the anti-erosion permeability of the magnesia carbon brick is improved.
