High-aluminum refractory high-strength castable | 50 |
Product Description:
High-strength and high-aluminum castables are a kind of low-cement castables, with a cement content of less than 8%.Dense refractory castable made of clay and high alumina raw materials.
Product Features:
High-strength and high-aluminum castables are used at temperatures above 1400 degrees, with an aluminum content of 74%. They are commonly used castables for kiln linings. They have high refractoriness, strong thermal stability, and good thermal shock resistance.Different from ordinary refractory castables, most of the calcium aluminate cement in the matrix is replaced by ultrafine powder, and at the same time, it is a product that meets and exceeds the performance of ordinary cement castables by adding appropriate additives.
Product Usage:
It is mainly used for the lining of industrial furnaces and other thermal equipment, the roof and tail furnace walls of CFB boilers.
