Refractory bricks
1. Refractory bricks Main Characters:
a. high refractoriness under load. The refractoriness is higher than fireclay bricks and much higher of the refractoriness under load with more content of alumina.
b. Thermal shock resistance: The thermal shock resistance for the ordinary high alumina bricks are largely depends on the mineral composition and chemistry microstructure. High alumina bricks’ thermal shock resistance is worse than that of fireclay bricks.
c. Chemical erosion resistance: High alumina bricks have good resistance to acid, alkali slag, erosion of liquid metal. In addition, they has good performance of oxidation reduction reaction.
2. Refractory bricks Applications:
refractory bricks are widely used in metallurgy furnace and other various kinds of kilns.
