- Commodity name： High-strength alkali-resistant bricks
Description
Introduction
☆ High-strength alkali-resistant bricks are refractory bricks made on the basis of ordinary types by adding silica, coke gemstones and appropriate additives to increase the compressive strength; high-strength alkali-resistant bricks have high strength, stable volume, penetration resistance, and Good alkali erosion and other characteristics; high-strength alkali-resistant bricks are mainly used in cement kiln preheaters, calciners, tertiary air ducts and other parts.
☆ Alkali-resistance brick is a kind of low alumina brick, the Al₂O₃ content is 35-25%, the main material is low alumina refractory clay, it is a kind of silica-alumina series refractory products with good alkali erosion resistance performance in cement kiln system.
