Njengoko ilizwe libeka ukubaluleka kukhuseleko lokusingqongileyo, njengohlobo lwenkunkuma eqinileyo, indlela yokusebenzisa i-steel slag ibe yingongoma ebalulekileyo. Eli nqaku lizisa isisombululo sobugcisa esibanzi sokuphinda kusetyenziswe i-steel slag. Itekhnoloji yokucubungula eyomileyo kufuneka iqinisekise ukubuyiswa okusebenzayo kweentsimbi kwelinye icala kunye nokusetyenziswa okubanzi kweentsalela zenkunkuma kwelinye icala. Amanyathelo alandelayo okucubungula i-steel slag achaziwe: Ukutyumza okukhethayo; ukwahlulwa kwemagnethi kunye nendima yesixhobo esitsha esisebenza nge-single-drive high-pressure roller mill ekusetyenzisweni okubanzi kwe-steel slag; ukusetyenziswa kwezixhobo ezintsha kunokunciphisa kakhulu iindleko zokutyumza i-steel slag, ngaloo ndlela kudale iingenelo ezingaphezulu zokusetyenziswa kwe-steel slag. Ukukhuthazwa kokusetyenziswa okubanzi kwe-steel slag kudale ithuba. Ukukhuthazwa kwale ngcamango ibanzi kushishino kufuna imizamo edibeneyo yeenkampani zokwenza intsimbi, iingcali zokucubungula izimbiwa kunye neengcali, ukuphunyezwa ngokubanzi kwesicelo, kunye namasebe okuthengisa nokukhuthaza.
Ukusetyenziswa kwe-slag yentsimbi ekwakheni
1) I-slag yentsimbi isetyenziselwa ukuvelisa isamente kunye nezinto ezidityanisiweyo zekhonkrithi. I-slag yentsimbi ineeminerali ezisebenzayo ezifana ne-triccalcium silicate (C3S), i-dicalcium silicate (C2S) kunye ne-iron aluminate eneempawu ze-hydraulic cementing, ezihambelana neempawu zesamente. Ke ngoko, ingasetyenziswa njengezinto eziluhlaza kunye ne-samente admixture ukuvelisa isamente engeyiyo i-clinker, isamente encinci ye-clinker. Isamente ye-slag yentsimbi ineempawu ezintle ezifana nokumelana nokuguguleka, amandla aphezulu e-flexural, ukumelana nokugqwala kunye nokumelana neqabaka.
2) I-slag yentsimbi ithatha indawo yelitye elityumkileyo kunye ne-aggregate entle. Ilitye elityumkileyo le-slag yentsimbi lineengenelo zokuba namandla aphezulu, umphezulu orhabaxa, ukumelana nokuguguleka okuhle kunye nokuqina, umthamo omkhulu, uzinzo oluhle, kunye nokudityaniswa okuqinileyo ne-asphalt. Xa kuthelekiswa nelitye eliqhelekileyo elityumkileyo, likwamelana neempawu zokuqhekeka kobushushu obuphantsi, ngoko ke lingasetyenziswa kakhulu kwi-backfill yobunjineli beendlela. I-slag yentsimbi, njenge-ballast kaloliwe, ineempawu zokungaphazamisi umsebenzi wonxibelelwano lwenkqubo kaloliwe kunye nokuqhuba kakuhle kombane. Ngenxa yokuba i-slag yentsimbi inokungena kwamanzi kakuhle kunye nokuphuma kwamanzi, izinto ezisetyenziswa ngesamente kuyo zinokuyenza iqine ibe ziingceba ezinkulu. I-slag yentsimbi ikwafanelekile ekwakhiweni kwendlela kwiindawo ezimanzi kunye neelwandle.
Okwangoku, indlela eqhelekileyo yokusebenzisa i-slag yentsimbi yasekhaya kukutyumza i-slag yentsimbi ukuya kwi-5mm ukuze kuthathelwe indawo isanti yomlambo njengezinto zokwakha, okanye ukugawula i-slag yentsimbi etyumkileyo ibe ngumgubo ocolekileyo ukuze isetyenziswe njengesongezelelo sesamente. I-Shandong Huate Magnetoelectric Technology Co., Ltd. ikwaqhube uphando olunzulu malunga nokusetyenziswa ngokupheleleyo kwe-slag yentsimbi, yasebenzisa ngobuchule i-roller mill ene-drive enye ekutyumzeni i-slag yentsimbi, yaphucula iteknoloji yokucubungula i-slag yentsimbi, kwaye yafumana iingenelo ezilungileyo kwezoqoqosho. Isetyenziswe ngempumelelo kwi-Pangang Mining nakwishishini elithile le-slag yentsimbi eLianyungang.
Inkqubo yemveli yemveliso ye-slag yentsimbi yile ilandelayo:
1) Iziqwenga ezinkulu zityunyuzwa ngesixhobo sokutyumza umhlathi ukuya kwi -50, kwaye isinyithi semagnethi sahlulwe nge-pulley yemagnethi.
2) Misela ubungakanani bokwahlulwa kwesinyithi ukuya kwi-+45 mm. I-0-45 mm eseleyo idla ngokusetyenziswa njengokwakhiwa kwendlela kunye nezinto zokuzalisa. Ukuze kwandiswe ixabiso lokusetyenziswa kwayo, i-slag yesinyithi inokwahlulwa ibe yi-0-4, 4-8 kunye nezinye iiklasi ezahlukeneyo. Le teknoloji ifuna imali encinci kunye neendleko zokusebenza eziphantsi. Nangona kunjalo, ngaphezulu kwe-50% yomxholo wesinyithi kwi-slag ugxininiswe kumandla e--10 mm, ngoko ke le teknoloji iya kubangela uninzi lokulahleka kwesinyithi, kodwa umxholo wesinyithi esinzima uya kwanda.
Ngoko ke, ukugaya okumanzi okucolekileyo kuye kwasetyenziswa kakhulu ngokukodwa kwi-slag eveliswayo ekwenzeni intsimbi ene-alloy ephezulu equlethe i-Cr, i-Ni, i-Mo, njl.njl. Iinkqubo eziqhelekileyo ziquka ukutyumza kunye nokugawula okucolekileyo okunezinyathelo ezimbini (i-rod mill/ball mill). Ekubeni isinyithi esine-ductility singelula ukusigaya, ukwahlula i-slag yesinyithi kunye nentsimbi kunokufezekiswa ngokusila okanye ukwahlulahlula. Ubunzima benxalenye yeminerali ye-slag buhlala bungaphezulu kwe-95% kwaye bungaphantsi kwe-0.2mm. Izinga lokubuyisela isinyithi lale nkqubo lidlula i-95%, kwaye isivuno se-metal concentrate eveliswayo yi-90 ukuya kwi-92%. Ngokwembono yokwahlula isinyithi kunye ne-slag, le nkqubo inokuthiwa yeyona nkqubo ilungileyo.
Eyona ngxaki iphambili yale nkqubo kukuba i-slag yentsimbi ehlukanisiweyo yi-slurry ecolekileyo. Ngenxa yokuba le nkqubo yinkqubo emanzi, kunzima ukuyisebenzisa ekwakheni izakhiwo. Ke ngoko, uninzi lwezinto ze-slag zentsimbi eziseleyo emva kokukhethwa kwesinyithi ziyalahlwa, kwaye oku kudla ngokuba ngenxa yeendleko eziphezulu zokomisa okumanzi kunye nemiqathango esemthethweni kwihlabathi liphela. Naluphi na usetyenziso olunexabiso eliphezulu lufuna ezinye iindlela zokulungisa i-slag emanzi (ukomisa, ukuqina, njl.njl.).
Kufuneka kukhethwe phakathi kwesantya sokubuyisa isinyithi okanye ukufumaneka kwe-slag eseleyo. Ngokwesiqhelo, olu khetho luxhomekeke kwixabiso lesinyithi esifunyenweyo.
Iinkqubo eziqhelekileyo kweli nqanaba zezi zilandelayo:
Iziqwenga ezinkulu zityunyuzwa ngesixhobo sokutyumza umhlathi ukuya kwi -50, kwaye isinyithi semagnethi sahlulwe nge-pulley yemagnethi.
I-slag yentsimbi engama-50 ityunyuzwa nge-hammer crusher okanye i-cone crusher, i-impact crusher, ihluzwe ngesihluzo esineengqimba ezininzi, imveliso yegrit engama-20-10 ingasetyenziswa njengegrabile, imveliso yegrit engama-10-1 ingasetyenziswa njengesanti ecolekileyo.
