Product Details

Product Description

Based on our over 20 years of experience in refractory industry(production &installation), we have a thorough understanding of the technology &market, which enables us to provide the best possible quality high alumina products in China.

High alumina bricks have many applications in various high temperature kilns, which provide better performance than fireclay based bricks or conventional fireclay bricks would not suffice.

Major Applications:

Hot blast furnaces

Carbon baking kilns

Power plants(CFB)

Cement Kilns

back-up layers of various kilns

etc...
