High-temperature-resistant magnesium-chromium castable prepared from waste magnesium-chromium bricks
The invention relates to a high-temperature-resistant magnesite-chrome castable prepared from magnesite-chrome waste bricks. The high-temperature-resistant magnesite-chrome castable is prepared from the following raw materials in parts by weight: 10-20 parts of waste magnesite-chrome bricks of which the granularity is greater than 3mm and less than or equal to 6mm; 30-40 parts of waste magnesite-chrome bricks with the particle size larger than 1 mm and smaller than or equal to 3 mm; 20-30 parts of waste magnesite-chrome bricks with the particle size larger than 0 mm and smaller than or equal to 1 mm; 5-15 parts of 325-mesh Barkstein refined chromium ore; 10-20 parts of 97 high-purity magnesia with a particle size of 200 meshes; 1-10 parts of 200-mesh pure calcium aluminate cement; 5-10 parts of 200-mesh pure calcium aluminate cement; 1-5 parts of alpha-Al2O3 micro powder of 325 meshes; 1-3 parts of boric acid; 1-5 parts of 325-mesh silica fume powder; and 1-5 parts of sodium hexametaphosphate. With the high-temperature-resistant magnesium-chromium castable prepared from the waste magnesium-chromium bricks adopted, secondary utilization of the waste magnesite-chrome bricks is realized, the castable is excellent in performance, the consumption of refractory materials is reduced, and the consumption of smelteries is reduced.
本发明涉及一种利用镁铬废砖制作的耐高温镁铬质浇注料，由以下原料按重量份配比而成：粒度大于3mm小于等于6mm的废镁铬砖10‑20份；粒度大于1mm小于等于3mm的废镁铬砖30‑40份；粒度大于0mm小于等于1mm的废镁铬砖20‑30份；325目的巴基斯坦精铬矿5‑15份；200目的97高纯镁砂10‑20份；200目的纯铝酸钙水泥1‑10份；200目的纯铝酸钙水泥5‑10份；325目的α‑Al2O3微粉1‑5份；硼酸1‑3份；325目的硅灰粉1‑5份；六偏磷酸钠1‑5份。优点是：实现废镁铬砖的二次利用，浇注料性能优越，降低了耐材的消耗，为冶炼厂降低了消耗。
