Kungekudala, umgca wokuvelisa umgubo we-slag kunye neyona ndawo inkulu yokuvelisa e-China yagqitywa kwaye yafakwa kwi-Shagang Group.Utyalo-mali olupheleleyo lwale projekthi malunga ne-170 yezigidi ze-yuan, kwaye kuqikelelwa ukuba iitoni ezingama-600000 ze-steel slag powder ziya kuveliswa ngonyaka.Ngenxa yobunzima obuphezulu be-slag yensimbi, i-particle diameter ye-ball mill yesiqhelo kunye ne-roller mill isekho malunga ne-6-8mm emva kokutyumza, okudinga ukuba amashishini okuvelisa i-samente asebenze kwakhona.Islag yentsimbiilitye lokusila elithe nkqo isetyenziswe kumgca wemveliso yensimbi ye-slag ye-Shagang, ethi "ishiya" ngokuthe ngqo ikhonkco eliphakathi.Ububanzi be-fineness ye-slag yensimbi inokufikelela malunga ne-0.003mm.Ngesiseko sokunciphisa ukusetyenziswa kwamandla kwenkqubo, inokunciphisa ingozi yokusingqongileyo, iphucule ixabiso elongezelelweyo lemveliso, ikhuthaze ngakumbi ukuguqulwa kwe-slag yensimbi ukusuka "kwinkunkuma eqinile" ukuya "kwimveliso", kunye nokufezekisa "ukuphucula kabini." ” yeenzuzo zokukhuselwa kwendalo kunye neenzuzo zoqoqosho.Oku kubonisa ukuba i-steel slag mill inethemba elihle lemarike.Njengobuchwephesha bentsimbi yentsimbi yokusila nkqo, iHCMilling (Guilin Hongcheng) iya kwazisa ukusetyenziswa kwemarike yentsimbi yentsimbi nkqo.

intsimbi slag yokusilailitye lokusila

Kuyaqondwa ukuba "i-steel slag grinding" yiprojekthi eyaziwayo yokukhusela indalo engqongileyo, iprojekthi yezoqoqosho enokuphinda isetyenziswe, kunye "nesibini sokutsiba" sonyango lwe-slag yensimbi e-Shagang.Ngo-2020, i-Shagang iya kwakha iprojekthi yonyango ye-slag ye-slag enkulu ye-3.3 yezigidi zeetoni e-China, kwaye ifezekise i-100% yokusetyenziswa okupheleleyo kwe-slag yensimbi ngokuhlukana kwamagnetic, ukutyumza, ukugaya intonga, ukuhlolwa kunye nokunye ukusetyenzwa okunzulu.Ekupheleni kuka-Oktobha waloo nyaka, phantse iitoni ze-600 ze-slag zensimbi ezivela e-Shagang zasetyenziswa ngempumelelo kwiprojekthi yokuguqulwa kwesiponji kwiindlela zikamasipala zaseZhangjiagang.Emva kweintsimbi slag yokusilailitye lokusilaumgca wokuvelisa ufakwe ekusebenzeni, i-slag yensimbi itshintshile ngokwenene "inkunkuma eqinile" ukuya "kwimveliso", kwaye izibonelelo zokuphinda zisetyenziswe "zomile kwaye zicinezelwe", zandisa ngakumbi ikhonkco loqoqosho oluluhlaza."Ubukhulu bezinto eziluhlaza yi-6-8mm, kwaye emva koko sizigaya nge-steel slag nkqo yokusila, kwaye ukucoleka kufikelela malunga ne-0.003mm ububanzi."Ngokutsho kochwephesha ovela kwi-workshop ye-pulverizing ye-Shagang New Materials Co., umgca wokuvelisa i-slag yensimbi eqhelekileyo malunga neetoni ze-300000 kulo lonke ishishini.Umgca wethu omtsha we-600000 wokuvelisa iitoni yireferensi yoshishino lonke kwaye ulungele ukusekwa kwemimiselo yoshishino esebenzayo.

Uphando malunga nophuhliso kunye nokusetyenziswa kwe-steel slag i-powder encinci sisihloko esishushu emva kokusetyenziswa kwe-slag micro powder kwiminyaka yamuva.Ukuveliswa kwe-powder powder okanye i-composite micro powder nge-steel slag kunokuphelisa ukuhlukana kokugaya kwimveliso ye-steel slag cement.Xa i-slag yensimbi igalelwe kwi-fineness ethileslag yentsimbi ilitye lokusila elithe nkqo, xa indawo ethile yomhlaba ingaphezulu kwe-400m2Kg, isinyithi sesinyithi sinokususwa kwinqanaba elikhulu.Isakhiwo sekristal sezinto eziphathekayo sihlengahlengiswa ngokutsha kwe-ultra-fine, kwaye imeko ye-particle surface iyatshintsha, Umphezulu unokuphucula kunye nokuvuselela ngomatshini umsebenzi we-slag yensimbi, ukunika umdlalo kwiimpawu ze-hydraulic cementing materials.Xa i-steel slag powder kunye ne-slag powder zixutywe, zinenzuzo ye-superposition.I-calcium hydroxide eyenziwe xa i-C3S kunye ne-C2S kwi-slag yensimbi i-hydrated yi-activator esisiseko ye-slag.Idatha yakutshanje ibonisa ukuba nangona ukusetyenziswa kwe-slag powder njenge-concrete admixture kunokuphucula amandla ekhonkrithi kunye nokuphucula 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 se-liquid kwikhonkrithi, yonakalise ifilimu ye-passive yokuqinisa kwikhonkrithi (pH <12.4 kulula ukuyonakalisa), kwaye ibangele ukubola kokuqiniswa kwikhonkrithi.Ukongeza, i-blast furnace slag ngumzimba we-vitreous kunye ne-C3AS kunye ne-C2MS2 njengezona zinto ziphambili.I-gellability ye-granulated blast furnace slag powder ivela ekuqhekekeni kwesakhiwo se-slag vitreous.Iimveliso ze-hydration zingenziwa kuphela phantsi kwesenzo seCa (OH) 2. I-slag yensimbi ine-alkalinity ephezulu (% CaO +% MgO) / (% SiO2), malunga ne-1.8 ~ 3.0.Izimbiwa ikakhulu C3S, C2S, CF, C3RS2, RO, etc. I fCaO kunye neeminerali esebenzayo kwi slag yentsimbi kuvelisa Ca (OH) 2 xa kuhlangana amanzi, nto leyo ephucula alkalinity ulwelo lwenkqubo yekhonkrithi, Inokusetyenziswa njengoko i-alkaline activator ye-slag powder.Ikhonkrithi exutywe ne-steel slag powder ineempawu zamandla aphezulu kwixesha elizayo.Ngoko ke, i-steel slag kunye ne-slag composite powder inokufunda omnye komnye, kwaye ukusebenza kuphelele ngakumbi.

Inkqubo yemveliso ye slag yentsimbi ilitye lokusila elithe nkqo idityaniswe ngokutyumza, ukugaya, ukomisa kunye nokukhethwa komgubo, obonakaliswe kukusetyenziswa kwamandla aphantsi, ukusebenza kakuhle kokutywinwa, indawo encinci yomgangatho, inkqubo elula, njl njl. isigxininisi somgubo, isantya sokuhamba komoya sefeni yokusila kunye noxinzelelo lokusila.Ngokutshintsha indlela yoyilo kunye neengqiqo kunye neteknoloji yenkqubo ekhulayo, utyalo-mali lwenkqubo yokusila ethe nkqo iyancipha kakhulu, elingana okanye iphezulu kancinane kunenkqubo yokusila yesekethe evaliweyo.Ngenxa yeenzuzo zayo ekusebenzeni kunye nokusetyenziswa kwamandla, inkqubo iya kusetyenziswa ngokubanzi nangaphezulu.I-HCMilling(Guilin Hongcheng) yintsimbi yobuchwephesha yentsimbi yokusila nkqo.YethuHLM intsimbi slagilitye lokusila elithe nkqo sisixhobo esifanelekileyo sokunceda ilitye lokusila elithe nkqo ukwandisa imarike yomgubo wentsimbi.Iyakwazi ukugaya i-steel slag powder kunye nommandla othile ophezulu ongaphezulu kwe-700, gcina iinkqubo ezimbini zokugaya kwangaphambili kunye nokugaya okokugqibela, kunye nokugqiba ukuveliswa kwe-slag powder kwisinyathelo esinye.
