The invention discloses a new refractory castable, which has the advantages of abrasion resistance, alkali resistance, erosion resistance and erosion resistance, and is a preparation method of a wear-resistant alkali resistant refractory castable. Wear resistant alkali resistant refractory castable prepared by the method of the material after 3 hours of 1100 DEG C burning resistance less than 3.5 / cm = 3, alkali resistance reached to level two. The use of a large cement kiln three wind pipe bend, air valve, cooler throat, wall and other parts, compared with refractory materials used at present, its good wear resistance, and excellent alkali erosion resistance, can greatly improve the operation rate of the cement kiln.
