Ultralow-carbon magnesia carbon brick for bottom of stainless steel ladle, and preparation method thereof
The invention provides an ultralow-carbon magnesia carbon brick for the bottom of a stainless steel ladle, and a preparation method thereof. The ultralow-carbon magnesia carbon brick for the bottom ofthe stainless steel ladle is prepared from, by mass, 50 to 120 parts of fused magnesite, 0.5 to 5 parts of graphite, 1 to 5 parts of liquid phenolic resin, 0.5 to 5 parts of carbon-containing resin powder, 0.1 to 5 parts of carbon black, 0.5 to 5 parts of MgO-Al2O3-ZrO2 composite powder, 0.5 to 8 parts of metal aluminum powder and 0 to 1 part of boron carbide. The ultralow-carbon magnesia carbonbrick for the bottom of the stainless steel ladle has very strong thermal shock stability and molten steel scouring resistance; the ultralow-carbon magnesia carbon brick does not recarburize molten steel; the heat conductivity is low, and the heat loss is reduced; CO2 emission is low, and environmental friendliness is achieved; and the use of natural resources is reduced in the production process.
本发明提供一种不锈钢钢包包底用超低碳镁碳砖及其制备方法，不锈钢钢包包底用超低碳镁碳砖按照质量份数计算，其制备原料包括：电熔镁砂50‑120份、石墨0.5‑5份、液态酚醛树脂1‑5份、含碳树脂粉0.5‑5份、炭黑0.1‑5份、MgO‑Al2O3‑ZrO2复合粉体0.5‑5份、金属铝粉0.5‑8份、碳化硼0‑1份。该不锈钢钢包包底用超低碳镁碳砖，具有很强的热震稳定性和抗钢水冲刷性能；且该超低碳镁碳砖对钢液不产生增碳；具有较低的热导率降低了热损失；CO2排放低，对环境友好；生产过程中减少了天然资源的使用。
