一种适于石化工业废液、废弃物焚烧的锆铬刚玉莫来石砖
摘要：
本发明公开一种耐火材料，一种适于石化工业废液、废弃物焚烧的锆铬刚玉莫来石砖，其特征在于，制造用物料的组分：合成莫来石骨料、合成锆刚玉骨料、刚玉细粉、α氧化铝微粉、复合结合剂、Cr2O3细粉和水。按配方量，将物料经行星混合机混合，压制成型，成型的砖坯经80～110℃烘烤，时间为24～48小时，在1560～1610℃下焙烧，时间为3.5～4.5小时。本发明还公开了锆铬刚玉莫来石砖的制造方法。本发明的有意效果在于锆铬刚玉莫来石砖，具有较高的耐火度和高温强度，同时具有抗侵蚀、抗热震、抗剥落和低蠕变的优良性能。适用于石化工业废液焚烧炉和回转窑式产业废弃物焚烧炉内衬。本发明的工艺简单，制造易于实现。
摘要（英）：

The invention discloses a refractory material, especially a chromium zirconium corundum mullite brick suitable for burning of waste liquid and wastes of petrochemical industry. The mullite brick is characterized by comprising synthetic mullite aggregate, synthetic corundum aggregate, corundum fine powder, alpha-alumina micropowder, a composite binder, Cr2O3 fine powder and water. According to a formula amount, the materials is mixed by using a planetary mixer and molded by pressing, and the molded adobe is fired under 80-110 DEG C for 24-48 hours, and roasted under 1560-1610 DEG C for 3.5-4.5 hours. The invention further discloses a preparation method of the chromium zirconium corundum mullite brick. The invention is beneficial in that the chromium zirconium corundum mullite brick is relatively high in refractoriness and high-temperature intensity, and has excellent performances of erosion resistance, thermal shock resistance, stripping resistance, and low creep deformation. The brick is suitable for inner liners of a waste liquid incinerator of the petrochemical industry and a waste incinerator of a rotary kiln industry, and is simple in technology and easy to realize the manufacture.
