High-temperature strong-alkaline-corrosion-resistant wear-resistant lining suitable for fuel gas flame-proof sintering lithium battery/sodium battery positive electrode material rotary kiln
The invention relates to a high-temperature strong-alkaline-corrosion-resistant wear-resistant lining suitable for a fuel gas flame-proof sintering lithium battery/sodium battery positive electrode material rotary kiln, which is prepared by the following steps: (1) weighing magnesium nitrate and aluminum nitrate, and dissolving the magnesium nitrate and the aluminum nitrate in deionized water; (2) weighing food-grade citric acid crystals with the content of 99% or above, then adding the citric acid crystals into the solution obtained in the step (1), stirring and dissolving fully, then heating the solution to 80-100 DEG C, and stirring and preserving heat for 1-3 hours to obtain a light yellow colloidal dispersion liquid; (3) weighing silicon carbide particles, corundum particles and magnesium aluminate spinel particles with different particle sizes according to a weight ratio of 3: 3: 4, adding barium carbonate powder, and uniformly mixing and stirring for later use; (4) adding the light yellow colloidal dispersion liquid into the mixed aggregate subjected to grading mixing treatment, then fully and uniformly mixing, and then aging; (5) forming; and (6) sintering. The metal sleeve has high-temperature strong alkali corrosion resistance and high wear resistance, and the thermal expansion coefficient is matched with that of the metal sleeve.
本发明涉及一种适用于燃气隔焰烧结锂电池/钠电池正极材料回转窑用高温抗强碱性腐蚀耐磨内衬，它包括（1）称取硝酸镁和硝酸铝后，溶于去离子水中；（2）称取含量99%以上的食品级柠檬酸晶体，然后将柠檬酸晶体加入到步骤（1）的溶液中搅拌溶解充分，然后将溶液加热至80‑100℃，搅拌保温1‑3小时后，得到呈浅黄色的胶体状分散液；（3）将不同粒径的碳化硅颗粒、刚玉颗粒、镁铝尖晶石颗粒，按照重量比3：3：4称料，同时加入碳酸钡粉末，混合搅拌均匀备用；（4）浅黄色胶体状分散液加入到级配混合处理的混合骨料，然后充分混合均匀，而后陈化；（5）成型；（6）烧结。本发明具有高温耐强碱腐蚀、高耐磨、热膨胀系数与金属套筒相匹配性能。
