Sebenzisa izimo ze izitini eziphikisayo zomlilo

Ngaphansi kwezimo ezijwayelekile, inhloso eyinhloko yezitini eziphikisayo ze-lining lining ukuthuthukisa ukusebenza kahle kwe-lining, kunokubambezeleka ukukhiqiza ngenxa yokulimala kwezitini eziphikisayo ngesikhathi sokucubungula. Ngakho-ke, izitini eziphikisayo zesithando somlilo kufanele zikhethwe ngokusho kokuphila nokusebenza kahle kwesithando somlilo. Isitini esiyi-refractory i-inorganic non-metallic material enomkhawulo wokumelana nomlilo omkhulu kuno-1580°C. Ukushisa okuphezulu nokuzinza okungekho umthwalo wezitini eziphikisayo, okungukuthi, izici zokungancibiliki nokuthambisa ngaphansi kwamazinga okushisa aphezulu kanye nokungabikho komthwalo, kubizwa ngokuthi i-refractoriness, eveza izici eziyisisekelo zezitini eziphikisayo.

Izitini eziphikisayo, njengezinto ezibalulekile zeziko lokushisa eliphezulu nezinye izikhungo ezishisayo, zingamelana nemiphumela ehlukahlukene yomzimba kanye nemishini. Ngakho-ke, kufanele kuhlangatshezwane namazinga ayisisekelo alandelayo:

(1) Ukuze kuhlangatshezwane nezidingo zokusetshenziswa kwezinga lokushisa eliphezulu, kufanele kube nezici zokungathambisi nokungancibiliki ezingeni lokushisa eliphezulu ngokwanele.

(2) Ingakwazi ukumelana nomthwalo wesithando somlilo nokucindezeleka okuvame ukusebenza ngesikhathi sokusebenza, ayinawo amandla esakhiwo, futhi ayithambisi, ikhubazekile futhi iwa emazingeni okushisa aphezulu. Ngokuvamile kuvezwa izinga lokushisa lokuthambisa umthwalo.

(3) Emazingeni okushisa aphezulu, umthamo uzinzile, futhi umzimba womlilo noma umzimba othululayo ngeke ugoqe ngenxa yokwanda ngokweqile komkhiqizo, noma imifantu ngenxa yokushwabana ngokweqile, ngaleyo ndlela kunciphise ukuphila kwesevisi. Ngokuvamile cabangela i-coefficient yokwanda okushisayo kanye nokunciphisa ukushisa kabusha (noma ukunwetshwa).

(4) Izitini eziphikisayo zithinteka kakhulu izimo zesithando somlilo. Ngenxa yoshintsho oluhle lokushisa nokushisa okungalingani, umzimba wesithando somlilo ulimala kalula. Ngakho-ke, kuyadingeka ukuthi kube nezinga elithile lokumelana nokushaqeka okushisayo.

(5) Ngesikhathi sokusetshenziswa, izitini eziphikisayo zivame ukufakwa i-oxid ngesisombululo esiwuketshezi, igesi noma i-organic organic matter, okubangela ukuthi umkhiqizo ugqwale futhi wonakaliswe. Ngakho-ke, umkhiqizo uyadingeka ukuthi ube nezinga elithile lokumelana nokugqwala.

(6) Enqubweni yokufakwa kwesicelo, izitini eziphikisayo zivame ukugqwala amalangabi nothuli olugeleza ngesivinini esiphezulu, ukugqwala okugqwalayo kwensimbi ewuketshezi kanye ne-slag encibilikisiwe, kanye nokulimala kokushayisana phakathi kwensimbi nezinye izinto zokusetshenziswa. Ngakho-ke, kuyadingeka ukuthi ube namandla anele kanye nokumelana nokugqwala.
