Izitena ze-alumina eziphantsi kakhulu kwisitovu esishushu

Ukuhamba kancinci kunye izitena alumina eliphezulu zizinto ezinqabileyo ezikumgangatho ophezulu ezenziwe ngealuminium, ifakelwe i-corundum, kunye ne-mullite edibeneyo njengezona zinto ziphambili ziphambili.

Iimbonakalo

1. Ukujonga kwakhona

Ukuphindaphindwa kwezitena ezisezantsi kunye nezine-alumina eziphezulu kuphezulu kunezitena zodongwe kunye nezitena ezinesilica, ezifikelela kwi-1750 ~ 1790 ℃, eyinto enqabileyo ekumgangatho ophezulu.

2. Layisha ubushushu obuthambileyo

Ngenxa yokuba iimveliso zealumina eziphezulu zineAl2O3 ephezulu, ukungcola okuncinci, kunye nemizimba yeglasi encinci enefusus, umthwalo othomalalisa ubushushu uphezulu kunowezitena zodongwe. Nangona kunjalo, ngenxa yokuba amakristali e-mullite engenzi ubume benethiwekhi, ubushushu obuthomalisayo bomthwalo abukho njengobude bezitena zesilica.

3. Ukuxhathisa i-Slag

Ukunyuka okuphantsi kunye nezitena eziphezulu ze-alumina ziqulethe i-Al2O3 engaphezulu, esondeleyo kwizinto ezingathathi hlangothi, kwaye inokuxhathisa ukhukuliseko lwe-slag ene-acid kunye ne-alkaline slag. Ngenxa yokuba iqulethe i-SiO2, ukubanakho ukumelana ne-alkaline slag kubuthathaka kunaleyo ye-acidic slag.

ukusebenzisa

Isetyenziselwa ubukhulu becala ulwelwesi lwefilos, umlilo oshushu, izithando somlilo zombane, amaziko odubulo, amaziko okubuyisela, kunye neekilns ezijikelezayo.
