High aluminum hook brick
High aluminum hook brick
Product advantages: low temperature creep, strong corrosion resistance, good thermal shock stability
nkọwa ngwaahịa
High-aluminum hook bricks with alumina content above 48% are neutral refractory materials. It is formed and calcined from bauxite or other raw materials with high alumina content. High-aluminum hook bricks have high thermal stability, and their refractoriness is above 1770℃. The slag resistance is better.
