Indlela yokwahlula umgangatho we izitena alumina eliphezulu?

isitena esiphezulu se-alumina sisixhobo esichasayo kunye ne-alumina njengeyona nto iphambili. Inkqubo yemveliso ye izitena alumina eliphezulu iyafana naleyo yezitena zodongwe ezininzi. Umahluko kukuba umlinganiselo we-clinker kumxube uphezulu kakhulu, onokuthi ufikelele kwi-90-95%. Ngaphambi kokutyunyuzwa, i-clinker kufuneka ihlelwe kwaye ihlolwe ukususa isinyithi, kwaye ubushushu bokudubula buphezulu. Nini izitena alumina eliphezulu ezifana ne-I kunye ne-II zitshiswa kwi-tonnel kiln, ubushushu buphakathi kwe-1500 kunye ne-1600 ° C.

1. Umbala wembonakalo kunye nenkangeleko yokuthambisa

Ukubona isitena esiphezulu se-alumina, siqala sijonge ukubonakala kwayo, umbala kunye nokuthambisa kwangaphandle. Ezinye izitena eziphakamileyo ze-alumina azikho kumgangatho ophezulu kakhulu, okubangela ukubonakala kakubi kwe-lubricity, kwaye ukomelela kwezitena eziphezulu ze-alumina akulungile.

Ukufana kwembonakalo kunye nombala wezitena eziphezulu ze-alumina zibonisa ukuba izinto eziphathekayo zixutywe ngokufanayo ngexesha lenkqubo yokuvelisa izitena eziphezulu ze-alumina. Ukusabalalisa okungafaniyo kwezinto eziphathekayo kuya kubangela ukusabalalisa okungafaniyo kwamandla ezitena eziphezulu ze-alumina, ngaloo ndlela ukunciphisa amandla onke kunye nobomi benkonzo yezitena eziphezulu ze-aluminium.

2, ukungcola kwangaphandle

Ukongeza, sihlala sibona amabala amnyama kumphezulu wezitena eziphezulu ze-alumina. Konke oku kukungcola kwimathiriyeli ekrwada. Kwithiyori, ukungcola okuncinci kungcono. Ekubeni obu kungcola ubukhulu becala i-iron oxide, iyancipha nje isinyithi esinyibilikisiweyo kwindawo yokushisa ephezulu kwi-oven, eya konakalisa isakhiwo sezitena eziphezulu ze-alumina kwaye zichaphazele ubomi benkonzo yezitena eziphezulu ze-alumina.
