High aluminum poly brick usually use high alumina bauxite clinker plus a small amount of clay, pouring and forming in the form of mud in gas or foam method after fine grinding, and finally fired in 1300 ~ 1500 ℃. Sometimes use industrial alumina instead of part of the bauxite clinker. High alumina poly brick is suitable for masonry lining and insulation layer, and the site of no strong high temperature melting materials erosion. When directly contacting with the flame, the surface contact temperature shall not be higher than 1350 ℃.
Features of High aluminum poly brick:
1. high compressive strength.
2. good thermal shock stability.
3. small re-burning line changes.
4. small thermal conductivity.
5. can reduce the heat capacity of the furnace wall.
6.promote the furnace heat efficiency.
7.according to the customer's design needs, finishing into a variety of special-shaped products.
Application of high aluminum poly brick:
used in metallurgy, machinery, ceramics, chemical industry kiln lining (not suffer from solution erosion) and insulation layer, is an ideal energy-saving product. The operating temperature is below 1350 ℃.
