1. Isimo samanje sokusetshenziswa kwensiza ye-steel slag:

I-steel slag powder sekuyisikhathi eside ifakiwe ezingeni likazwelonke njengengxube kasimende.Inani elikhulu lokuhlola okuqhathanisayo likufakazele ukuthi: Uma indawo ethile engaphezulu ye-steel slag powder ingaphezu kuka-420m2/kg, umsebenzi wayo ufana nalowo we-blast furnace slag.Ukuxuba okuhlanganisiwe kwe-steel slag powder kanye ne-slag powder akukwazi nje ukuthuthukisa ingxenye ye-steel slag powder ku-powder eyinhlanganisela, kodwa futhi kwandise inani lokushintshwa kwe-powder eyinhlanganisela kusimende ngesisekelo sokuqinisekisa ukusebenza kukakhonkolo, ukuze kuqhutshekwe phambili. ukunciphisa izindleko zokulungiselela ukhonkolo.Kunganciphisa ngokusobala ukuwohloka kokuncipha kwesibopho futhi kuthuthukise ukumelana nokuqhekeka kwesibophezelo.Lokhu kubonisa ukuthi imikhiqizo ye-steel slag powder inethuba elihle lemakethe.Njengamanje, ukuzinza kwevolumu ye-slag yensimbi kuncishisiwe ngenxa yokuba khona kwe-CaO ne-MgO yamahhala.Okuqukethwe okuphezulu kwe-iron oxide kwandisa ubunzima bokugaya, ukusetshenziswa kwamandla okuphezulu kwe-ton slag powder, kanye nobunzima bokucubungula i-steel slag powder.Ngakho-ke, umthamo wokuthengisa wemakethe ye-steel slag powder mncane, okwenza futhi i-steel slag powder ibe imakethe esafufusa ezothuthukiswa.

2. ukuxuba ukhonkolo kunikeza isikhala sokusebenzisa i-ultrafine steel slag ukugaya:

Ukuxutshwa kukakhonkolo endaweni eyodwa kuwushintsho olukhulu endleleni yokukhiqiza yamaphrojekthi wokwakha, futhi ingxenye yezicelo zikakhonkolo ezixutshwe ngomumo ibonisa izinga lokukhiqizwa kwezimboni okukhonkolo ezweni.Ukuzijwayeza kubonisa ukuthi ukusetshenziswa kukakhonkolo osulungele ukuxutshwa kungakhuphula umkhiqizo wabasebenzi ngaphezu kokuphindwe kabili, konga usimende ngo-10% ~ 15%, kunciphise izindleko zephrojekthi cishe ngo-5%, futhi kungaqinisekisa ikhwalithi yephrojekthi, ukonga umhlaba wokwakha, ukunciphisa ukungcoliswa kothuli, ukuze ukufeza ukwakhiwa okuluhlaza.Ukuthuthukiswa kokhonkolo wezohwebo kukhuthaza ukuthuthukiswa kokukhiqizwa kwe-slag powder futhi kwandise imakethe yesidingo se-slag powder.Imboni yaseShayina exubene ngokhonkolo exubile yasungulwa ngeminyaka yawo-1980, ekuqaleni eShanghai, eJiangsu nakwezinye izindawo, ngenxa yokwanda okuqhubekayo kwesikali sokwakha, ikakhulukazi ngenxa yentuthuko esheshayo yokwakhiwa kwamadolobha asogwini oluseningizimu-mpumalanga, kuhambisana ne uchungechunge lwezinqubomgomo ezisekelayo kanye nezinyathelo ezithathwe abaphathi bezokwakha, ukuze ukhonkolo osuxubile wedolobha unyuke ngo-15% ngonyaka.Ngenxa yokuthi intengo ye-slag ne-steel slag iphansi kunekasimende, ukhonkolo oxubene ne-slag ne-steel slag iyonga futhi ifanele ukusetshenziswa ekukhoneni okuxutshwe kakhulu kwezentengiselwano.Ukhonkolo owenziwe ngokuxuba i-slag ne-slag yensimbi nge-samente, itshe nesihlabathi esiphuzi kunezinzuzo zamandla aphezulu aphuzile, ukushisa okuphansi kwe-hydration, ukumelana okuhle kokugqoka kanye namandla okubopha okuphezulu anemigoqo yensimbi.Ilungele ikakhulukazi izakhiwo eziphakeme kakhulu, ama-DAMS, izikhumulo zezindiza, izisekelo ezinkulu ezijulile kanye namaphrojekthi angaphansi kwamanzi.Njengamanje, ukhonkolo wamandla aphezulu kakhulu ulungiswa ngokuxuba umlotha we-silica kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu, kodwa ukuntuleka kwezinto zokusetshenziswa ze-silica umlotha kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu kuyabiza, okuholela ezindlekweni eziphezulu zikakhonkolo.Ngezidingo eziphakeme neziphakeme zezimpawu zikakhonkolo kumaphrojekthi amakhulu akhethekile, ukwanda kwesidingo sikakhonkolo wezohwebo kuvule imakethe ebanzi yokusetshenziswa kakhulu kwe-slag ne-steel slag powder.Ukuqonda kwabantu izici ze-slag ne-steel slag powder, into entsha yokwakha, nayo iyajula.Ngokukhuthazwa nokusetshenziswa kukakhonkolo wezohwebo ezweni kanye nokuqaliswa kwamazinga kazwelonke ahlobene nemikhiqizo ye-slag nensimbi ye-slag powder, kanye nokuqaliswa kwezinqubomgomo ezifana nokwenqabela ngokuqinile ukuxuba ukhonkolo ezindaweni zokwakha ezindaweni zasemadolobheni, imakethe ye-slag nensimbi. I-slag powder izoba nkulu kakhulu, futhi ukusetshenziswa kwayo kuzoheha ukunakwa okwengeziwe.

3. inqubo yokulungiselela kanye nemishini yokugaya i-steel slag micro-powder eqondile iye yaduma futhi yasetshenziswa.

Njengamanje, ubuchwepheshe bokugaya obuqondile busetshenziselwa ukugaya i-steel slag micro-powder futhi kukhiqize imikhiqizo ethatha indawo ye-high-energy Cement clinker, okuyingxenye yobuchwepheshe bokukhiqiza obuphambili embonini.Esikhathini esidlule, ngokuvamile i-slag, i-steel slag kanye ne-cement clinker, i-gypsum, njll ndawonye, ​​​​ngokuhambisana nengxenye ethile yokugaya ekukhiqizeni ukugaya kukasimende.Ngenxa yokusanhlamvu okungalungile kwe-slag ne-steel slag, ukugaya akukwazi ukugaywa kahle kakhulu uma kuhlanganiswe ne-clinker kasimende, ukusebenza kwayo akukwazi ukuthuthukiswa ngokugcwele, futhi inani kanye nokusetshenziswa kwe-slag ne-steel slag kunqunyelwe ngezinga elithile.Ekulungiseni i-ultrafine powder kusuka ku-steel slag iyodwa, amabhizinisi e-Jiangsu iron nensimbi ahamba phambili.Amabhizinisi amaningi ensimbi amelwe i-Changzhou Zhongtian Iron and Steel akhe imigqa yokukhiqiza yensimbi ekhethekile ye-slag eqondile yokugaya.Njengomkhiqizi wokugaya we-slag micro-powder omile mpo, Imishini ye-HCM ihlinzeka ngosekelo lobuchwepheshe kumzila wenqubo yokugaya insimbi ye-slag kanye nokhiye wokukhiqiza imishini yokugaya eqondile.Izici zayo zobuchwepheshe ikakhulukazi lezi zici ezilandelayo: ukukhethwa kwesigayo esiqondile sokugaya insimbi ye-slag powder, enobuchwepheshe obuthuthukisiwe, ukukhiqizwa okuthembekile, izici eziphezulu zokukhiqiza kwabasebenzi, ngomshini oqondile ukukhiqiza ithani lendawo ethile engu-400m2/kg ~ 500m2/kg. i-slag, i-steel slag powder, kunokukhiqizwa komshini wokugaya ibhola wesisindo esifanayo sempushana esindisa ugesi 30% ~ 50%;I-powder enhle ye-slag ne-steel slag ixubene ngokuqondile kukhonkolo, okugcina inani likasimende futhi ngaleyo ndlela igcine ukusetshenziswa kwamandla okukhiqiza usimende.I-Slag, inqubo yokugaya i-steel slag, ingalungisa kalula ukucoleka kwemikhiqizo ngokwezidingo zemakethe.Ngokunyuka kokwengezwa kwe-slag ne-steel slag kukhonkolo, ukushisa kwe-hydration kanye nokuqukethwe kwezingxenye eziyingozi zekhonkrithi kungancishiswa, okudala izimo ezivumayo zokuthuthukisa ukusebenza kokhonkolo ngokusetshenziswa kwamandla aphansi.I-slag yensimbi igaywa ngempushana yokugaya eqondile, futhi impahla igaywa endaweni enomswakama ezingeni lokushisa eliphezulu (100℃ ~ 300℃).Iningi le-calcium oxide yamahhala ne-magnesium oxide yamahhala ku-steel slag micro-powder ifakwa emanzini abe yi-calcium hydroxide esebenza kakhulu ne-magnesium hydroxide.Ngaphezu kwalokho, ngenxa yokufakwa kwe-slag ne-steel slag kukhonkolo, ukusabela kwe-alkali aggregate kungancishiswa ngokuphumelelayo, ama-micro-cracks kakhonkolo angavinjelwa, futhi impilo yezakhiwo inganwetshwa.Ngakho-ke, ukhonkolo oxutshwe ne-slag powder wamukelwa yimboni yezokwakha ngezindawo zayo eziyingqayizivele.I-slag yensimbi yokugaya iyodwa ingasetshenziswa njengomkhiqizo wokukhiqiza ukhonkolo nokuxuba ngokuvumelana nezidingo zemakethe, futhi kungabuye kulungiswe ngokuvumelana nesidingo sokulungisa ukucolisa kanye nenani lokuxuba elizocushwa libe usimende ukudayiswa.

Iron and steel enterprises can take advantage of the existing regional location of steel mills, and the source of raw materials is fully guaranteed; The steel mill has advanced and strict scientific management experience, and has experienced technical team and staff team, which provides the guarantee of organization, technology and production management for the implementation of the project and market development; Steel plant power supply, water supply source reliable, convenient transportation, good cooperation conditions, construction conditions are very superior. To sum up, the construction of steel slag micro-powder projects in iron and steel enterprises can not only turn waste into treasure, improve the added value of steel making, create considerable economic benefits for iron and steel enterprises, but also protect the environment, in line with the policy direction of steel and cement industry structural adjustment. The development of steel enterprises layout steel slag powder project is a good thing to benefit the country and the people, has a broad future and is of great significance, and will play a positive role in promoting the construction of "waste free city" and promoting the sustainable development of the steel industry.
