Furnace lining material of titanium slag smelting submerged arc furnace and preparation method of furnace lining material
The invention discloses a furnace lining material of a titanium slag smelting submerged arc furnace and a preparation method of the furnace lining material, and belongs to the technical field of smelting furnaces, and the furnace lining material comprises the following raw materials in parts by mass: 60-90 parts of fused magnesia, 30-50 parts of high titanium slag, 20-30 parts of graphite micro powder and 0-5 parts of boric acid. The preparation method comprises the following steps: mixing and smelting the high titanium slag and the graphite micro powder, mixing with the fused magnesite, and adding boric acid for modification to prepare the furnace lining material for the inner wall of a titanium slag smelting submerged arc furnace. According to the furnace lining material, the problems that a furnace lining in the prior art is low in fire-resistant temperature, poor in corrosion resistance and poor in scouring resistance, and a slag liquid line, a liquid outlet and the position behind an electrode are eroded too fast are solved, the service life of the whole submerged arc furnace is effectively prolonged, cost is low, and good realizability and economic applicability are achieved.
一种钛渣冶炼矿热炉的炉衬材料及其制备方法，所属冶炼炉技术领域，炉衬材料的原料质量配比为电熔镁砂60～90份、高钛渣30～50份、石墨微粉20～30份和硼酸0～5份。制备方法为将高钛渣和石墨微粉进行混合熔炼后，与电熔镁砂进行混合，并加入硼酸改性，制备得到的炉衬材料用于钛渣冶炼矿热炉内壁。本发明的炉衬材料解决了现有技术炉衬耐火温度低、耐腐蚀性差、耐冲刷性差，以及渣液线、排液口处和电极背后位置被侵蚀过快等问题，有效延长了矿热炉整体的使用寿命，且成本低，具有良好的可实现性和经济适用性。
