一种金属结合高强度长寿命耐火材料及其制备方法
摘要：
本发明涉及一种金属结合高强度长寿命耐火材料及制备方法，其特征在于所述的耐火材料质量百分组成为：刚玉或者镁砂20‑30％，石英砂10‑20％，蓝晶石5‑10％，氧化铝微粉或氧化镁微粉20‑30％，硅微粉和水泥10‑20％，外加①钢纤维为总物料的30‑45wt％，②添加剂为总物料的0.2‑0.4％。本发明采用浇注工艺制备以提高耐火材料中钢纤维的含量。本发明提供的耐火材料中钢纤维含量高达45wt％，显示出优异的物化性能。
摘要（英）：

The invention relates to a metal combined high-strength long-life refractory material and a preparation method thereof. The metal combined high-strength long-life refractory material comprises the following components by mass percentage: 20-30% of corundum or magnesia, 10-20% of quartz sand, 5-10% of kyanite, 20-30% of alumina micro powder or magnesium oxide micro powder, 10-20% of silica micropowder and cement, and additionally added steel fiber which accounts for 30-45 wt% of that of total material, and an additive which accounts for 0.2-0.4 wt% of that of total material. A cast technology is employed for increasing the steel fiber content in the refractory material, the steel fiber content in the refractory material can reach as high as 45 wt%, and the refractory material has excellent physicochemical performance.
