Product Overview:
High alumina refractory clay is made of high alumina calcined bauxite, with soft clay binder or chemical binder. It can be widely used in all kinds of industrial kilns with high aluminum brick masonry, such as the roof, regenerator and combustion chamber of hot blast furnace, the bottom, hearth, belly and waist of blast furnace, as well as repairing the roof and wall of industrial kilns. The content of Al2O3 is determined according to the composition and application requirements of the high alumina brick in masonry parts.
Character:
1. Good plasticity and convenient construction;
2, High bond strength, strong corrosion resistance;
3. High fire resistance, up to 1650℃±50℃;
4. Good slag penetration resistance;
