Indlela yokuhlukanisa ikhwalithi ye izitini eziphakeme ze-alumina?

isitini esiphezulu se-alumina siyinto ephikisayo ene-alumina njengengxenye eyinhloko. Inqubo yokukhiqiza ye izitini eziphakeme ze-alumina ifana neyezitini zobumba ezinama-multi-clinker. Umehluko wukuthi ingxenye ye-clinker engxubeni iphezulu kakhulu, ingaba phezulu njenge-90-95%. Ngaphambi kokuchotshozwa, i-clinker idinga ukuhlungwa futhi ihlolwe ukuze kukhishwe insimbi, futhi izinga lokushisa lokudubula liphakeme kakhulu. Nini izitini eziphakeme ze-alumina ezifana ne-I kanye ne-II zishiswa kuhhavini lomhubhe, izinga lokushisa ngokuvamile liphakathi kuka-1500 no-1600°C.

1. Umbala wokubukeka nokuthambisa ukubukeka

Ukubona isitini se-alumina esiphezulu, siqala ngokubheka ukubukeka kwaso, umbala kanye nokuthambisa kwangaphandle. Ezinye izitini ze-alumina eziphakeme azizona ezekhwalithi enhle kakhulu, okuholela ekubukekeni okubuthakathaka kokuthambisa, futhi amandla ezitini eziphakeme ze-alumina awalungile.

Ukufana kokubukeka nombala wezitini eziphezulu ze-alumina kubonisa ukuthi izinto zixubene ngokulinganayo ngesikhathi sokukhiqizwa kwezitini eziphakeme ze-alumina. Ukusabalalisa okungalingani kwezinto kuzoholela ekusabalaliseni okungalingani kwamandla ezitini eziphezulu ze-alumina, ngaleyo ndlela kunciphise amandla aphelele kanye nempilo yesevisi yezitini eziphezulu ze-alumina.

2, ukungcola kwangaphandle

Ngaphezu kwalokho, sivame ukubona amabala amnyama ebusweni bezitini eziphakeme ze-alumina. Konke lokhu ukungcola ezintweni ezingavuthiwe. Ngokombono, ukungcola okuncane kungcono. Njengoba lokhu kungcola ngokuvamile kuyi-iron oxide, kumane kuncishiswe kunsimbi encibilikisiwe endaweni yokushisa ephezulu kuhhavini, okuzolimaza ukwakheka kwezitini eziphakeme ze-alumina futhi kuthinte impilo yesevisi yezitini eziphakeme ze-alumina.
