Magnesian castable and preparation method thereof
The invention discloses a magnesian castable and a preparation method thereof. The magnesian castable is prepared from the following components in parts by weight: 60-80 parts of magnesia fine powder, 10-20 parts of aluminum-magnesium spinel powder, 5-8 parts of silicon carbide, 2-4 parts of aluminum oxide micro powder, 2-3 parts of silicon micro powder, 5-8 parts of phenolic resin and 0.2-0.4 part of sodium hexametaphosphate. The magnesium castable has the beneficial effects that a new additive is adopted, and various components are scientifically proportioned, so that the prepared magnesium castable has good high-temperature resistance, high strength, high volume density after molding, low apparent porosity and strong oxidation resistance at high temperature, and is not easy to permeate and erode by high-temperature steel slag during use.
本发明一种镁质浇注料及其制备方法，由以下成分按重量份比例制成：镁砂细粉60‑80份、铝镁尖晶石粉体10‑20份、碳化硅5‑8份、氧化铝微粉2‑4份、硅微粉2‑3份、酚醛树脂5‑8份、六偏磷酸钠0.2‑0.4份。本发明的有益效果是：本发明采用了新的添加剂，对各种成分进行了科学的配比，制备的镁质浇注料具有良好的耐高温性能，强度高，成型后体积密度大，显气孔率低，高温下抗氧化性强，使用中不容易被高温钢渣渗透和侵蚀。
