Environment-friendly chrome corundum castable
The invention relates to an environment-friendly chrome corundum castable, and belongs to the field of inorganic non-metallic materials. The environment-friendly chrome corundum castable is prepared from, by mass, aluminum chromium slag, waste high-chromium bricks, chrome green, kyanite powder and activated aluminum oxide micro powder, an aluminum dihydrogen phosphate solution serves as a binding agent, a high-efficiency water reducing agent is added, mixing and grinding are conducted, and vibration casting forming is conducted. The invention has the beneficial effects that by using the reclaimed material, resources are saved, the cost is reduced, and the performance of the reclaimed material is better than that of the existing chromium corundum castable. More importantly, the phosphate has relatively strong O2 <-> binding capacity, so that the alkaline condition required by the calcium aluminate cement for forming hexavalent chromium salt is thoroughly relieved, and the chromium corundum castable is green and environment-friendly.
本发明涉及一种环保型铬刚玉浇注料，属无机非金属材料领域。按质量份数计，本发明环保型铬刚玉浇注料由铝铬渣、废旧高铬砖、铬绿、蓝晶石粉、活性氧化铝微粉组成，以磷酸二氢铝溶液为结合剂、加入高效减水剂混碾，震动浇注成形。本发明的益处为使用再生料既节约资源又降低成本，且其性能比现有的铬刚玉浇注料性能更优。更重要的是，磷酸盐有较强的O2‑结合能力，彻底解除铝酸钙水泥为形成六价铬盐要具备的碱性条件，使铬刚玉浇注料绿色环保。
