Environment-friendly low-carbon aluminum-magnesium spinel brick and preparation method thereof
The invention provides an environment-friendly low-carbon aluminum-magnesium spinel brick and a preparation method thereof. The environment-friendly low-carbon aluminum-magnesium spinel brick is prepared from the following components in parts by weight: 1 to 4 parts of composite graphitized carbon black, 50 to 65 parts of sub-white corundum, 10 to 25 parts of fused white corundum, 5 to 7.5 parts of fused magnesia, 1 to 2.5 parts of corundum fine powder, 0.5 to 3 parts of spinel fine powder, 3 to 6 parts of active alpha-alumina micro powder, 3 to 5.5 parts of fused magnesia powder, 3.5 to 5.5 parts of composite binding agent and 2.5 to 3.5 parts of additive, wherein the composite graphitized carbon black is less than or equal to 0.05; the sub-white corundum particles are less than or equal to 5; less than or equal to 3 of fused white corundum; fused magnesite < = 2; 1-2.5 parts of corundum fine powder < = 3; spinel fine powder < = 1; and less than or equal to 2 of fused magnesite powder. According to the environment-friendly low-carbon aluminum-magnesium spinel brick and the preparation method thereof provided by the invention, phenolic resin is not adopted, so that harmful gas cannot be generated to pollute the environment during heating, and the service life of the low-carbon magnesia carbon brick combined by the composite binding agent is twice that of a traditional magnesia-chrome brick.
本发明提供一种环保型低碳铝镁尖晶石砖及其制备方法。所述环保型低碳铝镁尖晶石砖，按照重量份数计算，包括：复合石墨化炭黑1‑4份、亚白刚玉50‑65份、电熔白刚玉10‑25份、电熔镁砂5‑7.5份、刚玉细粉1‑2.5份、尖晶石细粉0.5‑3份、活性α‑氧化铝微粉3‑6份、电熔镁砂粉3‑5.5份、复合结合剂3.5‑5.5和外加剂2.5‑3.5；其中，复合石墨化炭黑≤0.05；亚白刚玉的颗粒≤5；电熔白刚玉≤3；电熔镁砂≤2；刚玉细粉1‑2.5份≤3；尖晶石细粉≤1；电熔镁砂粉≤2。本发明提供的环保型低碳铝镁尖晶石砖及其制备方法没有采用酚醛树脂，因此在加热时就不会产生有害气体而污染环境，而采用复合结合剂结合的低碳镁碳砖其使用寿命是传统镁铬砖的两倍的优点。
