Refractory alumina bauxite concrete is the use of cement, refractory aggregate, admixture and water by a certain percentage of mixed molding, curing and hardening. Bauxite refractory concrete refractory brick with the same high temperature performance of the highest refractory temperature of 1650 degrees, when there are unparalleled advantages of refractory bricks. The refractory bricks in practical application of the formation of arbitrarily poor, and alumina refractory castable can be based on actual needs, according to design requirements, so that the internal structure of the drying furnace to form the ideal surface structure to form the ideal hot air. Thereby increasing the heat utilization rate. Shaped part of the refractory alumina brick masonry in the high temperature state of the overall strength is poor, resulting in residual shrinkage under high temperature, the roof is easy to collapse. The alumina refractory concrete structure is to make up for this shortcoming, it makes the furnace top as a whole structure, strength is very big, will not appear collapse phenomenon. Thereby prolonging the service life of the drying furnace.
The use of alumina castable materials concrete structure, greatly reducing the manufacturing cost. The use of alumina refractory concrete structure manufacturing and repair work is simple, convenient, easy to operate, repair time is short. In short, bauxite refractory concrete and refractory bricks compared to simplify the production process, reducing production costs and improve the quality of the drying furnace, is a better economic refractories.
