(1) High aluminum brick: A1203 content is greater than 75%, refractoriness is higher than clay brick, acid and alkali corrosion resistance is good, suitable for cement kiln burning belt and other uses, long service life, load soft > 1300℃.

(2) Dolomite brick: hanging kiln skin performance is good, good erosion resistance, but how many f-Ca0 bricks, easy hydration, difficult to transport and storage, less used in production.

(3) magnesia chrome brick: hanging kiln skin is good, mostly used for burning belt, the disadvantage is poor thermal shock resistance, plus positive hexavalent Cr is highly toxic, the international production and use of magnesia chrome brick countries gradually reduced, now the production unit of this brick to find substitutes as soon as possible, directly combined with magnesium brick: soft load > 1700℃; Common bonded magnesia brick: generally 0.6% deformation starting point 1500℃-1600℃; 4% deformation point, 1700 degrees Celsius.

(4) Spinel brick: mostly used for excessive belt, good thermal shock resistance, good resistance to reduction, but the refractoriness is slightly worse, aluminum magnesium spinel brick load soft > 1700℃, volume density 2.9-3.05g/cm2.

(5) Anti-spalling brick: this brick contains a small amount of Zr0, which occurs during the heating process to form cracks, and has strong alkali resistance, anti-spalling and slag resistance.

(6) phosphate brick; The refractoriness is low, but the strength is high and the thermal shock is good, and it is mostly used for grate cooling machine and kiln head cover.

(7) silicon carbide brick: high temperature resistance (about 1800 degrees, the load softening temperature is 1620-1640), the coefficient of thermal expansion is small, and the resistance to acute cooling and acute thermal wear resistance is good for cooling belt and kiln.

(8) Silica brick: good thermal shock, high strength, good wear resistance, suitable for excessive belt.

(9) alkali resistant brick: load soft starting temperature point > 1320℃, linear expansion coefficient 6*10-6.
