Full Size Fracture-resistant refractory bricks

Uncharacterized clay refractory bricks Fracture-resistant refractory bricks Building materials Pu shaped clay refractory bricks   Clay brick Al2O3 content is generally more than 40%, Fe2O3 content is less than 2.0~2.5%. The clinker in the ingredients is 65~85%, and the bonded clay is 35~15%. Will be crushed combined with clay and grinding fine clinker mixing and grinding, and then with particles of clinker together with the preparation of semi-dry mud, high-pressure molding, burned at about 1400 ℃, better performance. Clay bricks are weakly acidic at high temperatures, slightly less resistant to alkaline slag erosion, but with the increase in Al2O3 content and enhancement. Thermal stability than silicon bricks, magnesium bricks (see magnesium bricks) and other good.   Quality qualified high alumina clay bricks after drying treatment vacuum phosphate impregnation, the second low-temperature firing phosphate impregnated products, used for masonry blast furnace body lining. &nbs…
