Njengoba izwe lifaka ukubaluleka ekuvikelweni kwemvelo, njengohlobo lwemfucuza eqinile, indlela yokusebenzisa i-steel slag ibe yisihloko esibalulekile.Lesi sihloko sethula isixazululo esibanzi sobuchwepheshe sokugaywa kabusha kwe-slag yensimbi.Ubuchwepheshe bokucubungula okomile kufanele buqinisekise ukutholwa okusebenzayo kwezinsimbi ngakolunye uhlangothi kanye nokusetshenziswa okuphelele kwezinsalela zemfucuza ngakolunye.Izinyathelo ezilandelayo zokucubungula i-steel slag zichaziwe: Ukuchotshozwa okukhethiwe;ukuhlukaniswa kazibuthe kanye nendima yomshini omusha we-single-drive high-pressure roller mill ekusetshenzisweni okuphelele kwe-slag yensimbi;ukusetshenziswa kwemishini emisha kunganciphisa kakhulu izindleko zokuchotshozwa kwe-steel slag, ngaleyo ndlela kudale izinzuzo ezengeziwe zokusebenzisa i-slag yensimbi.Ukukhuthazwa kokusetshenziswa okuphelele kwe-slag yensimbi kuye kwadala ukuthi kube nokwenzeka.Ukugqugquzelwa kwalo mqondo obanzi embonini kudinga imizamo ehlanganyelwe yezinkampani ezikhiqiza insimbi, ochwepheshe bokucubungula izimbiwa kanye nezifundiswa, ukuqaliswa okuphelele kwesicelo, kanye neminyango yokumaketha nokukhuthaza.
Ukusetshenziswa kokwakhiwa kwe-slag yensimbi
1) I-Slag yensimbi isetshenziselwa ukukhiqiza usimende nezixube zikakhonkolo.I-slag yensimbi iqukethe amaminerali asebenzayo afana ne-tricalcium silicate (C3S), i-dicalcium silicate (C2S) kanye ne-iron aluminate enezakhiwo ze-hydraulic cementing, ezihambisana nezici zikasimende.Ngakho-ke, ingasetshenziswa njengendwangu eluhlaza kanye nengxube ye-cement yokukhiqiza usimende ongewona we-clinker, usimende omncane we-clinker.Usimende we-steel slag unezici ezinhle kakhulu ezifana nokumelana nokugqokwa, amandla aphezulu okuguquguquka, ukumelana nokugqwala kanye nokumelana nesithwathwa.
2) I-Slag yensimbi ithatha indawo yetshe elichotshoziwe kanye nokuhlanganisa okuhle.Itshe lensimbi elichotshoziwe le-slag linezinzuzo zamandla aphezulu, indawo embi kakhulu, ukumelana nokugqoka okuhle nokuqina, umthamo omkhulu, ukuzinza okuhle, kanye nenhlanganisela eqinile ne-asphalt.Uma kuqhathaniswa netshe elivamile elichotshoziwe, liphinde limelane nezici zokushisa okuphansi kokuqhekeka, ngakho-ke lingasetshenziswa kabanzi ekugcwaliseni ubunjiniyela bomgwaqo.I-Slag yensimbi, njenge-ballast yesitimela, inezici zokungaphazamisi umsebenzi wezokuxhumana wesistimu kaloliwe kanye nokuhamba kahle kukagesi.Ngenxa yokuthi i-steel slag inokungeneka okuhle kwamanzi kanye nokugeleza kwamanzi, izingxenye ze-cementitious kuyo zingayenza ibe yizicucu ezinkulu.I-Slag yensimbi ibuye ifanele ukwakhiwa komgwaqo emaxhaphozini nasemabhishi.
Njengamanje, indlela evamile yasekhaya yokusebenzisa i-slag yensimbi ukuchoboza i-slag yensimbi ibe ngu-5mm esikhundleni sesihlabathi somfula njengempahla yokwakha, noma ukugaya i-slag yensimbi echotshoziwe ibe yimpushana ukuze isetshenziswe njengesengezo sikasimende.I-Shandong Huate Magnetoelectric Technology Co., Ltd. yenze ucwaningo olunzulu ngokusetshenziswa okuphelele kwe-slag yensimbi, yasebenzisa ngobuchule umshini wokugaywa one-drive high-pressure roller ukuchotshozwa kahle kwe-slag yensimbi, yathuthukisa ubuchwepheshe bokucubungula i-steel slag, futhi yazuza izinzuzo ezinhle zezomnotho.Isetshenziswe ngempumelelo ePangang Mining kanye nebhizinisi elithile lensimbi e-Lianyungang.
Inqubo yokukhiqiza yendabuko ye-steel slag imi kanje:
I-1) Izingcezu ezinkulu zichotshozwa nge-crusher yomhlathi kuya ku-50, futhi insimbi kazibuthe ihlukaniswa ne-pulley magnetic.
2) Setha usayizi wokuhlukanisa wensimbi ku-+45 mm.I-0-45 mm esele ivame ukusetshenziswa njengokwakhiwa komgwaqo kanye nezinto zokugcwalisa.Ukuze ukwandise inani layo lesicelo, i-slag yensimbi ingahlukaniswa ibe yi-0-4, 4-8 namanye amamaki ahlukene.Ubuchwepheshe budinga imali encane kanye nezindleko eziphansi zokusebenza.Kodwa-ke, ngaphezu kwe-50% yensimbi yensimbi ku-slag igxilwe ku--10 mm force, ngakho-ke lobu buchwepheshe buzobangela ukulahlekelwa okuningi kwensimbi, kodwa okuqukethwe kwensimbi esindayo kuzokwanda.
Ngakho-ke, ukugaya okuhle okumanzi kuye kwasetshenziswa kabanzi ikakhulukazi ku-slag ekhiqizwa ekwenzeni insimbi ephezulu ye-alloy equkethe i-high-grade Cr, i-Ni, i-Mo, njll. Izinqubo ezijwayelekile zihlanganisa ukuchotshozwa kanye nezinyathelo ezimbili zokugaya kahle (induku yokugaya / i-ball mill. ).Njengoba insimbi ene-ductility akulula ukuyigaya, ukuhlukaniswa kwensimbi nensimbi ye-slag kungafinyelelwa ngokuhlunga noma ukuhlukaniswa.Ubuhle bengxenye yamaminerali ye-slag ngokuvamile bungaphezu kwama-95% nangaphansi kuka-0.2mm.Izinga lokubuyisela insimbi yale nqubo lidlula i-95%, futhi isivuno sokugxila kwensimbi ekhiqizwa yi-90 kuya ku-92%.Ngokombono wokuhlukanisa insimbi ne-slag, le nqubo ingashiwo ukuthi iyinqubo engcono kakhulu.
Ukungalungi okuyinhloko kwale nqubo ukuthi i-slag yensimbi ehlukanisiwe iyi-slurry enezinhlamvu ezinhle.Ngenxa yokuthi inqubo iyinqubo emanzi, kunzima ukufaka isicelo ekwakhiweni kwesakhiwo.Ngakho-ke, izinto eziningi zensimbi ze-slag ezisele ngemva kokukhethwa kwensimbi zilahliwe, futhi lokhu kuvame ukubangelwa izindleko eziphakeme zokumisa okumanzi kanye nemingcele yezomthetho emhlabeni jikelele.Noma yisiphi isicelo senani eliphakeme sidinga ezinye izindlela zokwelapha udaka olumanzi (ukoma, ukujiya, njll.).
Ngokuvamile ukukhetha kufanele kwenziwe phakathi kwezinga lokutholwa kwensimbi noma ukutholakala kwe-slag esele.Ngokuvamile, lokhu kukhetha kuncike enanini lensimbi etholiwe.
Izinqubo ezijwayelekile kulesi sigaba zimi kanje:
Izingcezu ezinkulu zichotshozwa nge-crusher yomhlathi ukuya ku-50, futhi insimbi kazibuthe ihlukaniswa ne-pulley magnetic.
-50 insimbi slag ichotshozwa ngesando crusher noma cone crusher, impact crusher, sieved ngokusebenzisa multi-layer sieve, -20-10 grit umkhiqizo ungasetshenziswa njengetshe, -10–1 grit umkhiqizo ungasetshenziswa njengesihlabathi esihle.

Ukuhlaziywa kosayizi wezinhlayiyana zokuphakelayo okungu-50mm kucrusher isando
-10 okusanhlamvu i-slag yensimbi igaywa ibe yibhola elomile libe yimpushana emihle engu- -200 mesh, bese kusetshenziswa isihlukanisi sikazibuthe sempushana eyomile kagesi ukuze kukhishwe insimbi njengesithako sikasimende.
