Kutshanje, umgca wokuvelisa umgubo we-slag wentsimbi onomthamo omkhulu wemveliso eTshayina ugqityiwe kwaye waqaliswa ukusebenza kwiShagang Group. Utyalo-mali olupheleleyo lwale projekthi lumalunga ne-170 yezigidi zeeyuan, kwaye kuqikelelwa ukuba iitoni ezingama-600000 zepowder ye-slag yentsimbi ziya kuveliswa minyaka le. Ngenxa yobunzima obukhulu be-slag yentsimbi, ububanzi be-particle ye-ball mill eqhelekileyo kunye ne-roller mill busemalunga ne-6-8mm emva kokutyunyuzwa, nto leyo efuna ukuba amashishini emveliso yesamente aphinde ayicubungule.i-slag yentsimbii-roller mill ethe nkqo Isetyenziswa kumgca wemveliso yesixhobo sokugalela inkunkuma sentsimbi saseShagang, esishiya ngokuthe ngqo ikhonkco eliphakathi. Ububanzi benkunkuma yentsimbi bunokufikelela kwi-0.003mm. Ngokusekelwe ekunciphiseni ukusetyenziswa kwamandla kwenkqubo, inokunciphisa iingozi zokusingqongileyo, iphucule ixabiso elongezelelweyo lemveliso, ikhuthaze ngakumbi ukuguqulwa kwenkunkuma yentsimbi ukusuka "kwinkunkuma eqinileyo" ukuya "kwimveliso", kwaye ifezekise "uphuculo oluphindwe kabini" lwezibonelelo zokhuseleko lokusingqongileyo kunye neenzuzo zoqoqosho. Oku kubonisa ukuba isixhobo sokugalela inkunkuma yentsimbi sinethuba elihle lemarike. Njengomatshini wokugaya inkunkuma yentsimbi oyingcali, iHCMilling (Guilin Hongcheng) iya kwazisa ukusetyenziswa kwemveliso yokugalela inkunkuma yentsimbi ethe nkqo.

ukugaya i-slag yentsimbiumsilo

Kuyaqondakala ukuba "ukugaya i-slag yentsimbi" yiprojekthi yokukhusela okusingqongileyo eyaziwayo kushishino, iprojekthi yoqoqosho enokusetyenziswa kwakhona, kunye "nokunyuka kwesibini" konyango lwe-slag yentsimbi eShagang. Ngo-2020, iShagang izakwakha iprojekthi enkulu yonyango lwe-slag yentsimbi eyi-3.3 yezigidi zeetoni eTshayina, kwaye ifezekise ukusetyenziswa ngokupheleleyo kwe-slag yentsimbi ngokwahlulahlula ngemagnethi, ukutyumza, ukugawula iintonga, ukuhluza kunye nokunye ukucutshungulwa okunzulu. Ekupheleni kuka-Okthobha waloo nyaka, phantse iitoni ezingama-600 ze-slag yentsimbi evela eShagang zasetyenziswa ngempumelelo kwiprojekthi yokuguqula isiponji yeendlela zikamasipala waseZhangjiagang. Emva kokubaukugaya i-slag yentsimbiumsiloUmgca wemveliso uyasebenza, i-slag yentsimbi itshintshe ngokwenene ukusuka "kwinkunkuma eqinileyo" ukuya "kwimveliso", kwaye izixhobo zokuphinda zisetyenziswe "zomisiwe zaza zacudiswa", nto leyo eyandisa ngakumbi uthotho lwezoqoqosho oluluhlaza. "Ububanzi bezinto ezikrwada yi-6-8mm, size emva koko sizigaye ngakumbi nge-steel slag vertical roller mill, kwaye ubuncinci bufikelela malunga ne-0.003mm ububanzi." Ngokutsho kwengcali evela kwindawo yokusebenzela yokucola i-Shagang New Materials Co., umgca wemveliso ye-steel slag eqhelekileyo umalunga neetoni ezingama-300000 kulo lonke ishishini. Umgca wethu omtsha wemveliso yeetoni ezingama-600000 yireferensi kulo lonke ishishini kwaye ulungele ngakumbi ukwakhiwa kwemigangatho esebenzayo yeshishini.

Uphando malunga nophuhliso kunye nokusetyenziswa komgubo we-slag micro powder luyinto eshushu emva kokusetyenziswa okukhulu komgubo we-slag micro kwiminyaka yakutshanje. Ukuveliswa komgubo we-micro powder okanye umgubo we-composite micro powder nge-slag yentsimbi kunokususa umahluko ekugugeni ekuvelisweni kwesamente ye-slag yentsimbi. Xa i-slag yentsimbi igutyungelwe yaba yincinci ethilei-slag yentsimbi i-roller mill ethe nkqo, xa indawo ethile yomphezulu ingaphezulu kwe-400m2Kg, intsimbi yesinyithi ingasuswa kakhulu. Ulwakhiwo lwekristale lwento luhlengahlengiswa ngokutsha ngokusila okucolekileyo kakhulu, kwaye imeko yomphezulu wesuntswana iyatshintsha, Umphezulu ungaphucuka kwaye uvuselele umsebenzi we-slag yentsimbi, nto leyo enika ukudlala kwiimpawu zezinto zokusimisa nge-hydraulic. Xa umgubo we-slag yentsimbi kunye nomgubo we-slag zidityanisiwe, zinenzuzo yokuba zibekwe phezulu. I-calcium hydroxide eyenziweyo xa i-C3S kunye ne-C2S kwi-slag yentsimbi zimanziswa yi-activator esisiseko ye-slag. Idatha yamva nje ibonisa ukuba nangona ukusetyenziswa komgubo we-slag njengomxube wekhonkrithi kunokuphucula amandla ekhonkrithi kwaye kuphucule ukusebenza kunye nokuqina komxube wekhonkrithi, i-alkalinity ephantsi ye-blast furnace slag (% CaO+% MgO)/(% SiO2+% Al2O3), malunga ne-0.9~1.2, iya kunciphisa kakhulu i-alkalinity yesigaba solwelo kwikhonkrithi, yonakalise ifilimu engasebenziyo yokuqinisa kwikhonkrithi (pH<12.4 kulula ukuyonakalisa), kwaye ibangele ukugqwala kokuqinisa kwikhonkrithi. Ukongeza, i-blast furnace slag ngumzimba we-vitreous one-C3AS kunye ne-C2MS2 njengezona zinto ziphambili. Ukukwazi kwe-gelability ye-granulated blast furnace slag powder kuvela ekuqhekekeni kwesakhiwo se-slag vitreous. Iimveliso ze-hydration zinokwenziwa kuphela phantsi kwesenzo se-Ca (OH) 2. I-slag yentsimbi ine-alkalinity ephezulu (% CaO+% MgO)/(% SiO2), emalunga ne-1.8~3.0. Iiminerali ikakhulu yi-C3S, C2S, CF, C3RS2, RO, njl. I-fCaO kunye neeminerali ezisebenzayo kwi-slag yentsimbi zivelisa i-Ca (OH) 2 xa zidibana namanzi, nto leyo ephucula i-alkalinity yolwelo kwinkqubo yekhonkrithi. Ingasetyenziswa njenge-alkaline activator ye-slag powder. Ikhonkrithi exutywe ne-steel slag powder ineempawu zamandla aphezulu kwixesha elizayo. Ke ngoko, i-steel slag kunye ne-slag composite powder zinokufunda omnye komnye, kwaye ukusebenza kugqibelele ngakumbi.

Inkqubo yemveliso i-slag yentsimbi i-roller mill ethe nkqo idityaniswe nokutyumza, ukugaya, ukomisa kunye nokukhetha ipowder, ebonakaliswa kukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle kokutywina, indawo encinci yomgangatho, inkqubo elula, njl. Ubunono obufunekayo kunye nokusasazwa kobungakanani bamasuntswana kunokufumaneka ngokulungelelanisa isantya esijikelezayo se-powder concentrator, izinga lokuhamba komoya kwefeni yemill kunye noxinzelelo lokugaya. Ngotshintsho lweendlela zoyilo kunye neengcamango kunye netekhnoloji yenkqubo ekhula ngokukhawuleza, utyalo-mali lwenkqubo ye-roller mill ethe nkqo luyancipha kakhulu, olulingana okanye luphezulu kancinci kunenkqubo ye-closed circuit ball mill. Ngenxa yeenzuzo zayo ekusebenzeni nasekusetyenzisweni kwamandla, le nkqubo iya kusetyenziswa ngokubanzi nangakumbi. I-HCMilling (Guilin Hongcheng) yi-roller mill yobuchwephesha yentsimbi ye-slag vertical. YethuI-HLM steel slagi-roller mill ethe nkqo sisixhobo esifanelekileyo sokunceda i-roller mill ethe nkqo ukuba yandise imakethi ye-steel slag powder. Ingagaya i-steel slag powder enommandla ophezulu ongaphezulu kwama-700, igcine iinkqubo ezimbini zokugaya kwangaphambili kunye nokugaya kokugqibela, kwaye igqibezele ukuveliswa kwe-steel slag powder ngenyathelo elinye.
