Iyiphi indlela efanele yokwelapha elwa ne-alkali izitini ezikhanyisayo?

1. Indlela eqondile yokuncibilika kwenhlabathi. Ngaphansi kwezimo zokuvala izinga lokushisa eliphezulu, insimbi encibilikisiwe ithintana ngokuqondile nebhulokhi yokuhlola ukuze kutholwe ukugqwala ukuze kulinganiswe izinguquko ezakhiweni ezihlukahlukene ngaphambi nangemuva kokuba isampuli igqwalile. Zombili izindlela zisebenzisa uguquko oluncane ukukhombisa ukumelana ne-alkali kwezitini eziphezulu ze-alumina refractory. Okungcono.

2. Indlela yokuguguleka exubile. Izinhlayiya ze-coke zixutshwe ne-anhydrous K2CO3, ibhulokhi yokuhlola ingcwatshwa kuyo, futhi ibhulokhi yokuhlola igqwalile ngaphansi kwezimo zokuvala izinga lokushisa eliphezulu ukuze kunqunywe ukuguqulwa kosayizi noma izinga lokunciphisa amandla ebhulokhi yokuhlola ngaphambi nangemva kokuguguleka kwayo.

3. Ukumelana ne-alkali kwezitini eziphikisayo yikhono lezitini eziphezulu ze-alumina eziphikisayo ukumelana nokugqwala kwe-alkali emazingeni okushisa aphezulu. Enqubweni yokuncibilikisa kwesithando somlilo, izitini eziphikisayo zizogqwala nge-alkali. Isibonelo, uma izinto zokusetshenziswa zengezwa kumaminerali aqukethe i-alkali, ukuguguleka kwalawa maminerali aqukethe i-alkali olwelweni lwe-aluminium-silicon nezitini ze-carbon refractory kuthintwa ukugxila kwe-alkali, izinga lokushisa kanye nomhwamuko wamanzi, okuhlobene nesevisi. impilo ye-blast furnace lining futhi ithuthukisa ukumelana nezitini eziphikisayo. Ukusebenza kwe-alkali kunweba impilo yesevisi yesithando somlilo esiqhumayo.
