Indlela yesithando somlilo se-Rock Yokukhiqiza I-Ferromanganese Yekhabhoni Ephansi Nemaphakathi

(1) Indlela yesithando somlilo sikagesi se-Rock
Indlela yesithando somlilo kagesi iyindlela eyinhloko yokuncibilikisa isicelo sokuncibilikisa isithando somlilo. Isisekelo esiyisisekelo sokusebenzisa indlela yesithando somlilo sikagesi iwukuxhumanisa izithando ezintathu.
Okokuqala, i-manganese slag evela emikhiqizweni yesithando somlilo sokucwenga ifakwa ku-rocker, bese kuba ingxubevange ye-silicon ewuketshezi ye-manganese ekhiqizwe isithando somlilo samaminerali ku-rocker. Ngejubane lika-55-60r/min elinyakazisa isithando somlilo, i-MnO ku-slag ye-manganese iyancipha nge-silicon ku-silicon alloy ye-manganese ngaphansi kwezimo ezinhle ze-kinetic. Ngemuva kokusabela, ukushisa kwamakhemikhali okukhishwa ngokushintsha kuqinisekisa ukuthi ukuncibilika kwenziwa ngokujwayelekile.

I-chemical reaction equation ithi:
2MnO + Si = = 2 Mn + SiO2. Ukuze unciphise ukuncipha kwe-MnO kuzidingo ezinqunyiwe ngemva kokulahlwa, I-slag yemfucuza icinywa ngamanzi futhi isetshenziselwe ukukhiqiza izinto zokwakha. Ingxubevange yoketshezi esithandweni sokucwengisisa kuze kucwengwe insimbi ye-mesocarbon manganese efanelekayo; Ukusabela kwamakhemikhali esithandweni sokucwenga kuyafana nendlela yokushisa ye-electrosilicon.


(2) Indlela ye-Silicon Thermal ye-Rock Furnace
Ukukhiqizwa kwe-low-carbon ferromanganese nge-silicon thermal method of rocker furnace kwaqalwa yi-Japan Shizhima iron alloy futhi kwafakwa ekukhiqizeni okusemthethweni. Iqala ukushiswa ngaphambili ku-shaft ibe ngu-600 ~ 800 ° C we-manganese ore kanye ne-lime ku-rocker, Bese ingxube ye-manganese ewuketshezi ekhiqizwa isithando sokushisa amaminerali, iqala i-rocker, isivinini sokuzamazama esingu-1 ~ 65r/min, Lapho ukusebenza, ijubane liyakhula kancane kancane kuye ngokuthi ukushuba kokusabela kwamakhemikhali esithandweni somlilo.


Ukusabela okuyinhloko kokunciphisa ama-manganese oxides yilezi: 2Mn2O3+Si===4MnO+SiO2 ne2MnO+Si===2MnO+SiO2
Iningi lokusabela kwe-desilicon kwenziwa ngenqubo ye-silicon alloy eshisayo-kuya-manganese, futhi ingxenye encane yenziwa ukunyakazisa okugcwele kwe-rocker. I-silicon ku-alloy ngokuyisisekelo i-oxidized, ukusabela kuvame ukuzola lapho isithando somlilo sokulahla, i-slag ethululiwe i-condensate ngemva kokuchotshozwa ukuze isetshenziswe esithandweni somlilo esincibilikisa i-silicon alloy. Ukusakaza kwengxubevange yoketshezi ngemva kokupakishwa kahle kwenombolo yepuleti.
