Performance Index Of High Aluminum Castable
High aluminum castable is a kind of low cement castable, the cement content is less than 8%, with high bauxite clinker as the aggregate, refractory clay as the powder, adding aluminate cement and sodium tripolyphosphates according to the formula ratio of mixed refractory castable, its use temperature above 1400 degrees, aluminum content of 74%, is commonly used castable kiln lining, with high refractoriness, Strong thermal stability, good thermal shock resistance and other characteristics
Unlike ordinary refractory castables, most of the calcium aluminate cement in the matrix is replaced by ultrafine powder, and at the same time, with the addition of appropriate additives, to reach and exceed the performance of ordinary cement castables.
