Izindlela zokunciphisa izindleko zokugqwala kwe-refractory lining esithandweni

Ngokusebenzisa inani elikhulu locwaningo lokuhlola ukumelana ne-slag kanye nokusebenza kwangempela kwesiguquli, olunye ulwazi lokumelana nokugqwala kwemigqa ephikisayo lungatholakala:

(1) Ukwakheka kwensimbi encibilikisiwe kunomthelela obalulekile empilweni yolwelwesi oluphikisayo, okuqukethwe kwe-silicon, ihlathi, nesibabule.

(2) Ukushisa okuphezulu kakhulu kwesiguquli kuzoholela ekwehleni kwempilo yolayini lwesithando somlilo. Uma izinga lokushisa lokugcina lingaphezu kuka-1700°C, njalo ukwanda ngo-10°C kuzokwandisa kakhulu izinga lokugqwala kolwelwesi oluphikisayo lwesithando somlilo.

(3) Ukwandisa i-alkalinity ye-slag kunenzuzo ekunciphiseni ukugqwala kwe-slag ku-refractory eyisisekelo.

(4) Ukwandisa okuqukethwe kwe-Mg0 ku-slag kunganciphisa ukugqwala kwe-slag kulwelwesi oluphikisayo lwesithando somlilo.

(5) Ukwandisa okuqukethwe kwe-Fe0 ku-slag kuzobangela ukugqwala kwempahla ephikisayo yolayini lwesithando somlilo ukuthi kukhule.

(6) Esigabeni sokuqala sokuguqulwa kwesiguquli, isisekelo se-slag siphansi, futhi ulwelwesi lugqwalile kakhulu. I-Dolomite slag kufanele isetshenziselwe ukwenza okuqukethwe kwe-Mg0 ku-slag eduze nesimo sokugcwala.

(7) I-fluorite iphinde igxumeke ulayini lwesithando somlilo, ngakho inani le-fluorite elengeziwe kufanele lehliswe ngangokunokwenzeka.

(8) Phakathi kwe-dolomite ne-magnesia dolomite refractories, i-Mg0 inokumelana nokuguguleka kwe-slag okungcono kune-Ca0, kodwa ukuba khona kwe-Ca0 kungathuthukisa izinga lokushisa eliphezulu le-thermoplasticity kanye nokumelana nokungena kwe-slag kwama-refractories.

(9) Izinto ezingasetshenzisiwe zezifanisi zothango lwesithando somlilo ziyadingeka ukuze zibe nokuhlanzeka okuphezulu. Isibonelo, isihlabathi se-magnesium dolomite sidinga ukungcola okuphelele kwe-SiO2+A12O3+FeO ngaphansi kuka-3%; ezinye ezifana ne-magnesia ehlanganisiwe, i-graphite, njll. nazo zinezidingo ezifanayo.
