Andalusite is a kind of advanced refractory raw material,at room temperature heated to about 1350 degree ,start into acicular mullite crystal, forming good mullite network structure, the volume expansion of about 4 percent .
Refractoriness nyob rau hauv ntau tshaj 1800 degree, thiab tsis kam mus rau thermal shock, mechanical zog yog loj, siab tiv thaiv -thermal shocking, siab slag kuj muaj zog, refractoriness nyob rau hauv load yog siab, siab tshuaj stability thiab muaj zog tsis kam mus tshuaj corrosion.
Introduce the andalusite to high alumina brick, the production of andalusite high alumina brick than ordinary high alumina brick has the more and better performance.
Zoo dua thermal shock stability
Better high anti-thermal shocking
Zoo dua slag corrosion kuj
Cov tshuaj tiv thaiv corrosion zoo dua
Therefore, andalusite high alumina brick are more versatile , use effect is better.
