Conclusions
An investigation was carried out of the abrasion resistance of aluminosilicate refractories for rotary kilns by two methods, viz., on a sandblaster and on a grinding wheel. The first method gave more precise and reliable results. The test conditions on a sandblaster are optimal with an air pressure of 1.5 kgf/cm2.
The results of the investigation of the abrasion resistance and its variation with the elastic and strength properties of aluminosilicate brick were evaluated by methods of mathematical statistics. It was found that the abrasion resistance of aluminosilicate refractories depends largely on the strength and elastic modulus of the product.
The abrasion resistance determined on a sandblaster is a reliable criterion for a prediction of the potential durability of refractories in the cold zones of rotary kilns.
The bricks produced by the Novomoskovsk Refractories Plant from semiacid clays are more resistant to abrasion than the chamotte bricks produced by that Plant, a fact which is demonstrated by the performance of these brick types in the rotary kilns of the Achinsk Alumina Combine and the Magnezit Combine.
