Low-carbon magnesia carbon brick and preparation method thereof
The invention provides a low-carbon alumina-magnesia carbon brick and a preparation method thereof. The low-carbon alumina-magnesia carbon brick is prepared from the following raw materials in parts by weight: 50 to 70 parts of high-alumina bauxite, 10 to 20 parts of fused magnesite, 15 to 25 parts of alumina-magnesia spinel powder, 4 to 6 parts of aluminum-calcium slag powder, 0.5 to 1 part of graphite, 2 to 4 parts of activated alumina micro powder, 0.2 to 0.4 part of silicon nitride, 8 to 10 parts of phenolic resin and 0.2 to 0.4 part of sodium dodecyl benzene sulfonate. By optimizing the raw material components of the low-carbon alumina-magnesia carbon brick and selecting a novel additive, the purpose of improving the erosion resistance, thermal shock resistance and slag resistance of the low-carbon alumina-magnesia carbon brick is achieved.
本发明提供一种低碳铝镁碳砖及其制备方法，所述低碳铝镁碳砖由如下原料按重量份比例制成：高铝矾土50‑70重量份、电熔镁砂10‑20份、铝镁尖晶石粉15‑25份、铝钙渣粉4‑6份、石墨0.5‑1份、活性氧化铝微粉2‑4份、氮化硅0.2‑0.4份、酚醛树脂8‑10份、十二烷基苯磺酸钠0.2‑0.4份；通过对低碳铝镁碳砖的原料成分进行优化以及选用新型外加剂，实现改善低碳铝镁碳砖抗侵蚀性、抗热震性和抗渣性的目的。
