Titanium extraction tailing combined corundum refractory material and preparation method thereof
The invention discloses a titanium extraction tailing combined corundum refractory material and a preparation method thereof. The invention relates to the technical field of waste treatment and resource utilization. The preparation method comprises the following steps: by taking 74-91 wt% of tabular corundum, 5-16 wt% of titanium extraction tailings and 4-10 wt% of alumina micro powder as raw materials, adding a water reducing agent, and uniformly mixing to obtain a premix; and adding water into the premix, uniformly stirring, carrying out casting molding, carrying out room-temperature curing, demolding and drying to obtain a corundum precast block, and carrying out high-temperature heat preservation to obtain the titanium extraction tailing combined corundum refractory material. The prepared titanium extraction tailing combined corundum refractory material is large in volume density, high in fracture-resistant and compression-resistant strength, good in high-temperature strength and excellent in slag corrosion resistance.
本发明公开了一种提钛尾渣结合刚玉质耐火材料及其制备方法。本发明涉及废弃物处理及资源化利用技术领域。制备方法为：以74～91wt％的板状刚玉、5～16wt％的提钛尾渣和4～10wt％的氧化铝微粉为原料，加入减水剂，混合均匀，得到预混料；向预混料中加入水，搅拌均匀，浇注成型，经过室温养护、脱模、干燥，制得刚玉预制块，再经过高温保温得到提钛尾渣结合刚玉质耐火材料。所制备的提钛尾渣结合刚玉质耐火材料体积密度大、抗折耐压强度高、高温强度好和抗渣侵蚀性优良。
