The invention relates to a preparation method of a chromite roasting rotary kiln burning zone castable. The castable is composed of aggregate, a matrix, and a binder. The aggregate is composed of 35 to 40 wt% of high bauxite and 25 to 30 wt% of ferrotitanium slag particles. The matrix is composed of 20 to 25 wt% of high bauxite fine powder, 6 to 11 wt% of fly ash micro-powder, and 1 to 3 wt% of aluminum fluoride micro-powder. The binder is phosphoric acid and accounts for 8 to 10 wt% of the total weight of the matrix and the aggregate. The castable has the characteristics of low cost, simple technology, high compactness, large cold state compression strength, and strong slag corrosion resistant performance, and is suitable for the preparation of a chromite roasting rotary kiln burning zone.
本发明涉及一种铬铁矿焙烧回转窑烧成带浇注料的制备方法，所述浇注料由骨料、基质料为原料，外加结合剂组成，所述骨料由35wt％～40wt％的高铝矾土颗粒和25wt％～30wt％的钛铁渣颗粒组成，所述基质料由20wt％～25wt％的高铝矾土细粉、6wt％～11wt％的粉煤灰微粉和1wt％～3wt％的氟化铝微粉组成；所述结合剂为磷酸，加入量为所述基质料与所述骨料之和的8wt％～10wt％。本发明所述浇注料除具有成本低廉、工艺简单的特点外，所制备的浇注料致密度高、冷态耐压强度大、抗渣侵蚀性强，特别适合于制作铬铁矿焙烧回转窑烧成带。
