Low-carbon environment-friendly aluminum carbon brick and preparation method thereof
The invention discloses a low-carbon environment-friendly alumina-carbon brick and a preparation method thereof, and relates to the technical field of alumina-carbon bricks, the low-carbon environment-friendly alumina-carbon brick comprises the following raw materials by weight: 70-85 parts of mixed high bauxite, 1-5 parts of graphite, 2.5-3 parts of a binder, 0.5-1 part of nanoscale carbon black, 2-8 parts of environment-friendly coal pitch, and 15-20 parts of silicon carbide; the mixed high-alumina bauxite comprises 10-20 parts of high-alumina bauxite with the particle size of 5-4 mm; 40-55 parts of high-alumina bauxite with a particle size of less than 4 mm; according to the low-carbon environment-friendly aluminum carbon brick, the preparation method is simple, the nano-scale carbon black can reduce the apparent porosity of the aluminum carbon brick, increase the volume density and improve the strength, corrosion resistance, thermal stability and the like of the magnesium carbon brick, meanwhile, the environment-friendly coal pitch effectively improves the compression strength of a finished product of the magnesium carbon brick, and due to the addition of the environment-friendly coal pitch, the environment-friendly coal pitch can effectively improve the compressive strength of the finished product of the magnesium carbon brick. And the low-carbon and environment-friendly effects are achieved.
本发明公开了一种低碳环保型铝碳砖及其制备方法，涉及铝碳砖技术领域，该低碳环保型铝碳砖，该低碳环保型铝碳砖的原料按照重量份组分为：混合高铝矾土70‑85份、石墨1‑5份、结合剂2.5‑3份、纳米级炭黑0.5‑1份、环保煤沥青2‑8份、碳化硅15‑20份；所述混合高铝矾土包括：粒径5‑4毫米高铝矾土10‑20份；粒径4毫米以下高铝矾土40‑55份；本发明的低碳环保型铝碳砖，其制备方法简单，纳米级炭黑能够降低铝碳砖的显气孔率，增大体积密度，能够提高镁碳砖的强度、耐侵蚀性和热稳定性等，同时环保煤沥青有效提高了镁碳砖成品的耐压强度，且环保煤沥青的加入，达到低碳环保效果。
