2 - MAGNESIA-CARBON BASIC CASTABLE FOR SECONDARY REFINING FURNACE
Provided is magnesia-carbon basic castable for a secondary refining furnace. The magnesia-carbon basic castable for a secondary refining furnace of the present invention has a basic composition, as a main ingredient, comprising: 87-92 wt% of magnesia clinker; 2-4 wt% of crystalline graphite; 1-2 wt% of fine graphite; 2-4 wt% pitch powder; 4-5 wt% of silicon powder; and a residual amount of unavoidable impurities. Also, the magnesia-carbon basic castable comprises, with respect to 100 parts by weight of the main ingredient, an additive comprising: 1-2 parts by weight of ultrafine silica powder; 1-1.5 parts by weight of B4C powder; 0.1-0.3 parts by weight of carbon fiber; and 1-1.5 parts by weight of metal fiber. According to the present invention, steelmaking productivity can be improved.
