Zirconium oxide-magnesium aluminate spinel composite refractory material with high thermal shock resistance and erosion resistance
The invention belongs to the field of inorganic non-metallic materials, and mainly relates to a high-thermal-shock and anti-erosion zirconium oxide-magnesium aluminate spinel composite refractory material. The material ratio is as follows: the monoclinic zirconium oxide particles with the particle size of 2-1mm account for 15-25%; the monoclinic zirconium oxide particles with the particle size of 1 to 0.125 mm account for 45 to 55 percent; the stable zirconia fine powder with the particle size of less than 0.045 mm accounts for 20-25%; the magnesium aluminate spinel fine powder with the particle size of less than 0.045 mm accounts for 3-5%; the monoclinic zirconium oxide micro powder with the particle size of less than 0.003 mm accounts for 2-5%. Adding 3-6% of resin or paper pulp waste liquid as a binding agent, mixing, molding, drying, and sintering at 1650-1700 DEG C; the zirconium oxide-magnesium aluminate spinel composite refractory material prepared by the method has the characteristics of high thermal shock resistance and excellent erosion resistance, and the production process is simple and easy to popularize.
本发明属于无机非金属材料领域，主要涉及一种高热震、抗侵蚀氧化锆‑镁铝尖晶石复合耐火材料。材料配比为：2‑1mm的单斜氧化锆颗粒占比15‑25%；1‑0.125mm的单斜氧化锆颗粒占比45‑55%；小于0.045mm的稳定氧化锆细粉占比20‑25%；小于0.045mm的镁铝尖晶石细粉占比3‑5%；小于0.003mm的单斜氧化锆微粉占比2‑5%。外加3‑6%的树脂或纸浆废液为结合剂，经过混合、成型和干燥后，于1650‑1700℃烧成。利用该方法制备的氧化锆‑镁铝尖晶石复合耐火材料具有热震性高、抗侵蚀性优异的特点，并且生产工艺简单、易于推广。
