1.7 Fe2O3 Clay fire Brick

Definition:

    Special Shaped Clay Fired Brick is matching characterized by good resistance to corrosion and abrasion, The advantage are good thermal shock resistance, good spelling resistance, high mechanical strength, good volume stability under high temperature.

    The mineral composition of Special Shaped Clay Fired Brick is mainly kaolinite (Al2O3·2SiO2·2H2O) and 6% to 7% impurities (oxides of potassium, sodium, calcium, titanium, and iron). The firing process of Special Shaped Clay Fired Brick is mainly the process of continuous dehydration and decomposition of kaolin to form mullite (3Al2O3·2SiO2) crystals. The SiO2 and Al2O3 in the clay brick form eutectic low-melting silicate with impurities during the firing process, which surrounds the mullite crystals.
    Special Shaped Clay Fired Brick  can resist the erosion of acidic slag and acidic gas, and have a slightly weaker resistance to alkaline substances. Clay bricks have good thermal properties and are resistant to rapid cold and rapid heat.

Advantage:

Lower thermal conductivity
Lower bulk density
Light weight character
Lower creep rate in high temp
Good thermal shock resistance performance
Higher temperate resistant with good refractoriness

Application: 

Iron&steel making industry:Blast furnace,hot blast furnace(stove),pellet shaft furnace,hot metal ladle,steel ladle, tundish,heating furnace,soaking pit furnace,heat treatment furnace,refining furnace,reheating furnace,metal mixter furnace,annealing furnace, cupola furnace,electric arc furnace,induction furnace,AOD furnace,VOD furnace,etc thermal technology equipment.
