Okuqukethwe kwesibabule okuphansi kunsimbi encibilikisiwe encibilikisiwe ngesithando somlilo esincibilikayo

Uma uncibilikisa insimbi ewukhonkolo nge- ukuchithwa kwesithando somlilo, ngenxa yenani elikhulu le-scrap esithandweni somlilo kanye nezinsimbi zensimbi zengulube ezincane, okuqukethwe kwesibabule ezithanjeni kuphansi ngokwemvelo, futhi akukho ukuthintana ne-coke phakathi nenqubo yokuncibilikisa, futhi ayikho inqubo yokumunca isulfure i-coke. Ensimbini encibilikisiwe etholwe ngokwengeza isulfure nokuncibilika, okuqukethwe kwesibabule kuvamise ukuba ngaphansi kuka-0.06%. Ngensimbi encibilikisiwe enesulfure ephansi, kuyiqiniso elaziwayo ukuthi umphumela wokwelashwa kwe-inoculation mubi.

Ngakho-ke, lapho ukuncibilika esithandweni sokuncibilika kwe-induction, ukunakwa okukhethekile kufanele kukhokhwe kokuqukethwe kwesibabule ensimbi ekhonjiwe, futhi kufanele kugcinwe ngaphezu kwe-0.06%. Uma ingekho ingxenye yesulfure ezithakweni, ngokuvamile inani elifanelekile le-ferrous sulfide lingengezwa ukwandisa isulfure.
