SK Series High Alumina Bricks

Product Details:

SK series high alumina 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 of the SK series high alumina bricks: The thermal shock resistance for the SK series high alumina bricks are largely depends on the mineral composition and chemistry microstructure. SK series high alumina bricks’ thermal shock resistance is better than that of fireclay bricks.
c. Chemical erosion resistance: SK series high alumina bricks have good resistance to acid, alkali slag, erosion of liquid metal. In addition, they have good performance of oxidation reduction reaction.

Applications of SK series high alumina bricks
 SK series high alumina bricks are widely used in metallurgy furnace and other various kinds of kilns.
