Environment-friendly magnesia-alumina-carbon brick
The invention relates to an environment-friendly magnesia-alumina-carbon brick which is mainly prepared from the following components in parts by mass: 35-45 parts of magnesia particles, 5-10 parts ofmagnesia fine powder, 10-20 parts of aluminum-zinc metal composite powder, 2-5 parts of silicon dioxide micro powder, 1-3 parts of colorless corundum fine powder, 2-4 parts of a complex magnesia-alumina adhesive, 0.1-0.2 part of wash oil, 3-5 parts of carbon black and 2-3 parts of silicon carbide micro powder. According to the magnesia-alumina-carbon brick, the oxidation resistance can be remarkably improved by adding a small amount of wash oil, and the medium-high temperature strength of a magnesia-alumina-carbon brick product can be improved through compatibility of colorless corundum finepowder and silicon carbide; meanwhile, the magnesia-alumina-carbon brick has the advantages of low carbon content and low apparent porosity.
本发明涉及一种环保型镁铝碳砖，主要由以质量份数计的以下成分组成：镁砂颗粒35‑45份、镁砂细粉5‑10份、铝锌金属复合粉10‑20份、二氧化硅微粉2‑5份、无色刚玉细粉1‑3份、络合镁铝胶黏剂2‑4份、洗油0.1‑0.2份、炭黑3‑5份、碳化硅微粉2‑3份。本发明的镁铝碳砖通过加入少量洗油能够显著提高抗氧化性能，并通过无色刚玉细粉与碳化硅的配伍能够提高镁铝碳砖产品的中高温强度；同时，本发明的镁铝碳砖具有含碳量低、显气孔率低的优点。
