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 .
Eldfastur í meira en 1800 gráður, og viðnám gegn hitaáfalli, vélrænni styrkur er mikill, mikill andstæðingur-varmaáfall, mikil gjallþol er sterk, eldföst undir álagi er mikil, mikill efnafræðilegur stöðugleiki og sterk viðnám gegn efnatæringu.
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.
Betri hitaáfallsstöðugleiki
Better high anti-thermal shocking
Betri tæringarþol gegn gjall
Betri efnafræðileg tæringarþol
Therefore, andalusite high alumina brick are more versatile , use effect is better.
