发明内容
本发明针对现有技术的不足，提供了一种致密度好、晶相稳定、吸水率低、热震稳定性好，大大提高抗侵蚀性和抗热应力疲劳性的回转窑内衬用高热震铬钢玉料及其制备方法以及应用。
为实现本发明目的，提供了以下技术方案：一种回转窑内衬用高热震铬钢玉料，其特征在于按质量百分比计包括以下组份：颗粒直径为1~5m的一级板状白刚玉颗粒50%~60%、合成铬钢玉细粉10%~25%、σ氧化铝微粉1%~4%、氧化铬细粉0.5%~2.0%、氧化铝微粉7%~10%、氧化铝晶须1%~3%、外加剂1.5%~2.5%、有机结合剂2%~5%。
作为优选，合成铬钢玉细粉包括：氧化铝微粉、耐火级氧化铬粉，氧化铝微粉：氧化 铬粉的重量百分比为=75wt%:25 wt%。
作为优选，氧化铝微粉中Al2O3＞99%，颗粒大小为800~900目。
作为优选，耐火级氧化铬粉中Cr2O3＞99%，颗粒大小为320~400目。
为实现本发明目的，提供一种回转窑内衬用高热震铬钢玉料制备方法，其特征在于包括以下步骤：
a.合成铬钢玉细粉: 用氧化铝微粉和耐火级氧化铬粉进行球磨混合，混合均匀后用有机结合剂结合，然后用500T油压机压制而成，再高温烧成，制得铬钢玉合成料；高温烧成后的铬钢玉合成料进行破碎磨细处理，铬钢玉合成料在气流磨中进行粘磨处理，细度达到小于等于320目，制得合成粘磨细粉；合成粘磨细粉首先进行一次酸洗然后进行碱洗，最后进行二次酸洗，烘干制得合成铬钢玉细粉备用；
b.将一级板状白刚玉颗粒、合成铬钢玉细粉、σ氧化铝微粉、氧化铬细粉、氧化铝微粉、氧化铝晶须、外加剂、有机结合剂混合，在强制式搅拌机里进行搅拌，制得成品料。
作为优选，强制式搅拌机里进行搅拌的步骤为：先用板状刚玉颗粒和氧化铝晶须进行搅拌3-5分钟，然后加结合剂进行搅拌5-分钟，最后加其余材料进行搅拌25-30分钟。
作为优选，铬钢玉合成料高温烧成温度为1750℃，烧成时间为72小时。
作为优选，外加剂为氧化铝纤维、五氧化二钒的一种或组合。
