REFRACTORY MATERIAL FOR CEMENT INDUSTRY KILNS AND USE THEREOF

摘要

THE INVENTION RELATES TO A REFRACTORY MATERIAL FOR CEMENT INDUSTRY KILNS AND THE USE THEREOF. THE INVENTIVE MATERIAL CAN BE USED INSIDE CEMENT INDUSTRY KILNS IN ORDER TO COUNTERACT THE THERMAL AND PHYSICO-CHEMICAL DEFORMATION THAT OCCURS INSIDE THE SAID KILNS. THE INVENTION COMPOSITION IS BASED ON A COMBINATION OF A PERCENTAGE BY WEIGHT EQUAL TO OR GREATER THAN 10 OF ANDALUSITE ( AI11 SIO4 ), A PERCENTAGE BY WEIGHT EQUAL TO OR GREATER THAN 10 OF SILICON CARBIDE ( SIC ) AND A PERCENTAGE BY WEIGHT EQUAL TO OR GREATER THAN 5 OF CLAY. MOREOVER, KAOLINITE ( AI4 [(OH)8 (SIO4)4] ) CAN BE USED INSTEAD OF ANDALUSITE IN EQUAL PROPORTIONS. THE SAID REFRACTORY MATERIAL CAN BE USED TO LINE THE INSIDE OF THE CEMENT KILNS IN THE CALCINATION AREAS ( 2 ), IN THE KILN OUTLET ( 6 ) AND IN THE COOLERS ( 7 ). FIGURE 1
