Aluminum Carbon Brick
Burning microporous alumina-carbon brick is a refractory product made of high-quality bauxite clinker, silicon carbide, carbon particles, graphite, and a binder after being mixed at a certain ratio, and then press-molded. Mainly used for masonry lining. According to the physical and chemical indicators, it is divided into WLT-1, WLT-2 and WLT-3.
Physical and chemical indicators:
|WLT-1||WLT -2||WLT -3|
|Al2O3 % ≥||65||60||55|
|C % ≥||11||11||9|
|TFe % ≤||1.5||1.5||1.5|
|Compressive strength at room temperature Mpa ≥||60||50||40|
|Bulk Density g/cm³ ≥||2.75||2.55||2.45|
|Apparent porosity % ≤||16||17||18|
|Alkali resistance (strength reduction rate) % ≤||10||10||15|
