I-Ferrosilicon

Umkhiqizo oyinhloko we-Dilifui-ferrosilicon, umkhiqizo wekhwalithi ephezulu osetshenziswa njengento ebalulekile eluhlaza embonini yensimbi.Ukuhlanzeka kungase kucaciswe ngokuvumelana nesidingo sekhasimende.

Incazelo

I-Ferrosilicon (FeSi) iyingxubevange ye-silicon nensimbi.I-ferrosilicon evamile ye-Dilifu iqukethe i-silicon engu-75% kanye nensimbi engu-20-24%.Umthamo wonyaka wokukhiqiza eDelifu ungamathani ayi-100,000.Ukukhiqizwa kusekelwe ku-quartz, i-iron ore, amalahle, i-coke kanye ne-biocarbon.I-alloy isetshenziswa kakhulu njenge-deoxidant kanye ne-alloying element ekukhiqizeni insimbi nensimbi.I-FeSi inyusa amandla, ubulukhuni, izinga lokushisa kanye nokumelana nokugqwala ensimbi.

I-3-4 kilograms ye-FeSi isetshenziselwa ukukhiqiza ithani elilodwa le-carbon steel evamile, kuyilapho insimbi engagqwali idinga izikhathi ezingu-5-10 zalesi samba se-FeSi.Ngakho-ke, sihlala sizungezwe imikhiqizo equkethe i-ferrosilicon.

Ukukhiqizwa kwe-Ferrosilicon

Ngamafuphi, inqubo ingase ichazwe kanje: Insimbi yensimbi (Fe2O3), i-quartz (SiO2) ne-carbon (C), ngendlela yamalahle, i-coke ne-biocarbon, yengezwe phezulu kwesithando somlilo.Ama-electrode amathathu esithandweni ukushisa impahla.Cishe ku-2000˚C ikhabhoni ihlangana nomoya-mpilo ku-quartz futhi sisele ne-silicon ewuketshezi.I-iron oxide kuma-pellets e-iron ore ihlangana nekhabhoni ngokusabela okufanayo futhi yakhe insimbi emsulwa.Ingxube ye-iron encibilikisiwe ne-silicon bese ishaywa ngamaledi.Insimbi iyapholiswa futhi ichotshozwe ibe yizicucu zosayizi oguquguqukayo, ukuhlangabezana nesidingo sekhasimende.

Ikhwalithi

I-Delifu iqinisekiswe ngokuhambisana ne-ISO-9001 kanye ne-ISO-14001.igxile kwikhwalithi, idala uhlobo lomkhiqizo, isiza amakhasimende futhi ithwala isibopho emphakathini.Ngakho-ke, ithole ukuphawula okuhle ngazwi linye okuvela ezimbonini ezinkulu ezihlukahlukene. Ukubambelela esimisweni sokukhonza amakhasimende ngenhliziyo yonke ngokusebenzisa izinguquko nentuthuko, inkampani ibhekene nomphakathi wamazwe ngamazwe nezimboni ezihamba phambili futhi ilwela ukuba “iminyaka eyikhulu, iphezulu. 100 kanye ne-10-billion” ibhizinisi.
