1. Isimo samanje sokusetshenziswa kwemithombo yensimbi:

Impuphu ye-slag yensimbi sekuyisikhathi eside ifakiwe endinganisweni kazwelonke njengengxube yesamente. Inani elikhulu lokuhlolwa kokuqhathanisa liye lafakazela ukuthi: Lapho indawo ethile ebusweni bempuphu ye-slag yensimbi ingaphezu kuka-420m2/kg, umsebenzi wayo ufana nowe-blast furnace slag. Ukuhlanganiswa okuhlanganisiwe kwempuphu ye-slag yensimbi kanye nempuphu ye-slag akugcini nje ngokuthuthukisa ingxenye yempuphu ye-slag yensimbi kumpuphu ehlanganisiwe, kodwa futhi kwandisa inani lokufakwa esikhundleni kwempuphu ehlanganisiwe ku-simende ngesisekelo sokuqinisekisa ukusebenza kwekhonkrithi, ukuze kuncishiswe izindleko zokulungiselela ikhonkrithi. Kunganciphisa ngokusobala ukuguquguquka kokuncipha kwe-binder futhi kuthuthukise ukumelana kokuqhekeka kwe-binder. Lokhu kubonisa ukuthi imikhiqizo yempuphu ye-slag yensimbi inethuba elihle emakethe. Njengamanje, ukuzinza kwevolumu ye-slag yensimbi kuncishisiwe ngenxa yokuba khona kwe-CaO yamahhala kanye ne-MgO. Okuqukethwe okuphezulu kwe-iron oxide kwandisa ubunzima bokugaya, ukusetshenziswa kwamandla aphezulu kwempuphu ye-ton slag, kanye nobunzima bokucubungula impuphu ye-slag yensimbi. Ngakho-ke, inani lokuthengisa lemakethe yempuphu yensimbi lincane, okwenza futhi impuphu yensimbi ibe yimakethe ekhulayo ezothuthukiswa.

2. Ukuxuba ukhonkolo kunikeza isikhala sokusetshenziswa kokugaya insimbi ethambile kakhulu:

Ukuxuba ukhonkolo okuhlanganisiwe kuyinguquko enkulu endleleni yokukhiqiza yamaphrojekthi okwakha, futhi isilinganiso sezicelo zekhonkolo ezihlanganisiwe sibonisa izinga lokukhiqizwa kwezimboni zekhonkolo ezweni. Umkhuba ubonisa ukuthi ukusetshenziswa kokhonkolo oluhlanganisiwe kungakhuphula umkhiqizo wabasebenzi ngaphezu kokuphindwe kabili, konge usimende ngo-10% ~ 15%, kunciphise izindleko zephrojekthi cishe ngo-5%, futhi kungaqinisekisa ikhwalithi yephrojekthi, konge umhlaba wokwakha, kunciphise ukungcola kothuli, ukuze kufezwe ukwakhiwa okuluhlaza. Ukuthuthukiswa kokhonkolo wezohwebo kukhuthaza ukuthuthukiswa kokukhiqizwa kwempuphu ye-slag futhi kwandisa imakethe yokufunwa kwempuphu ye-slag. Isitshalo sokuxuba ukhonkolo esihlanganisiwe saseShayina sasungulwa ngawo-1980, ekuqaleni eShanghai, eJiangsu nakwezinye izindawo, ngenxa yokwanda okuqhubekayo kwesilinganiso sokwakha, ikakhulukazi ngenxa yentuthuko esheshayo yokwakhiwa kwamadolobha asogwini oluseningizimu-mpumalanga, kuhlanganiswe nochungechunge lwezinqubomgomo nezinyathelo ezisekelwayo ezithathwe yiziphathimandla zokwakha, ukuze ukhonkolo oluhlanganisiwe oluhlanganisiwe lwedolobha lukhuphuke ngo-15% ngonyaka. Ngenxa yokuthi intengo ye-slag ne-steel slag iphansi kuneyesimende, ukhonkolo oxutshwe ne-slag ne-steel slag uyonga futhi ufanelekela ukusetshenziswa kukhonkolo yezentengiselwano exutshwe kakhulu. Ukhonkolo owenziwe ngokuxuba i-slag ne-steel slag ne-cement, itshe nesihlabathi esiphuzi unezinzuzo zamandla aphezulu okugcina isikhathi, ukushisa okuphansi komswakama, ukumelana okuhle nokuguguleka kanye namandla aphezulu okubopha ngezinsimbi zensimbi. Ifaneleka kakhulu ezakhiweni eziphakeme, ama-DAMS, izikhumulo zezindiza, izisekelo ezinkulu ezijulile kanye namaphrojekthi angaphansi kwamanzi. Njengamanje, ukhonkolo onamandla kakhulu ulungiswa kakhulu ngokuxuba umlotha we-silica kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu, kodwa ukuntuleka kwezinto zokusetshenziswa zomlotha we-silica kanye ne-ejenti yokunciphisa amanzi esebenza kahle kakhulu kuyabiza, okuholela ezindleko eziphezulu zekhonkolo. Njengoba izidingo ziphezulu neziphezulu zezimpawu zekhonkolo kumaphrojekthi akhethekile amakhulu, isidingo esikhulayo sekhonkolo yezentengiselwano sivule imakethe ebanzi yokusetshenziswa kabanzi kwe-slag ne-steel slag powder. Ukuqonda kwabantu izici ze-slag ne-steel slag powder, izinto zokwakha ezintsha, nakho kuyajula. Ngokukhuthazwa nokusetshenziswa kwekhonkrithi yezentengiselwano ezweni kanye nokusetshenziswa kwezindinganiso zikazwelonke ezihlobene nemikhiqizo ye-slag ne-steel slag powder, kanye nokusetshenziswa kwezinqubomgomo ezifana nokuvimbela ngokuqinile ukuxuba ikhonkrithi ezindaweni zokwakha ezindaweni zasemadolobheni, imakethe ye-slag ne-steel slag powder izoba nkulu kakhulu, futhi ukusetshenziswa kwayo kuzodonsela ukunaka okwengeziwe.

3. inqubo yokulungiselela kanye nemishini yokugaya mpo yensimbi ye-slag micro-powder iye yathandwa futhi yasetshenziswa

Njengamanje, ubuchwepheshe bokugaya obuqondile busetshenziselwa ukugaya i-slag micro-powder yensimbi nokukhiqiza imikhiqizo ethatha indawo ye-clinker yesimende enamandla aphezulu, okuwubuchwepheshe bokukhiqiza obuthuthukisiwe embonini. Esikhathini esidlule, ngokuvamile i-slag, i-slag yensimbi kanye ne-clinker yesimende, i-gypsum, njll. ndawonye, ​​​​ngokwesilinganiso esithile sokugaya ekukhiqizweni kwesimende. Ngenxa yokungagayeki kahle kwe-slag kanye ne-slag yensimbi, ukugaya akukwazi ukugaywa kahle kakhulu uma kuxutshwe ne-clinker yesimende, ukusebenza kwayo akukwazi ukuthuthukiswa ngokugcwele, futhi inani kanye nokusetshenziswa kwe-slag kanye ne-slag yensimbi kunqunyelwe ngezinga elithile. Ekulungiseleleni i-ultrafine powder evela ku-slag yensimbi yodwa, amabhizinisi ensimbi nensimbi aseJiangsu ahamba phambili. Amabhizinisi amaningana ensimbi amelwe yiChangzhou Zhongtian Iron and Steel akhe imigqa ekhethekile yokukhiqiza inqubo yokugaya ye-slag yensimbi. Njengomkhiqizi we-slag micro-powder wensimbi, i-HCM Machinery inikeza ukwesekwa kobuchwepheshe endleleni yenqubo yokugaya ye-slag yensimbi e-ultrafine kanye nokukhiqizwa kwemishini yokugaya eqondile eyinhloko. Izici zayo zobuchwepheshe ngokuyinhloko yizici ezilandelayo: ukukhethwa kwempuphu yensimbi yokugaya eqondile, enobuchwepheshe obuthuthukisiwe, ukukhiqizwa okuthembekile, izici zokukhiqiza okuphezulu kwabasebenzi, kanye nempuphu eqondile ukukhiqiza ithani lendawo ethile yobuso engu-400m2/kg ~ 500m2/kg, impuphu yensimbi yokugaya, kunokukhiqiza kwendabuko kwempuphu yebhola enesisindo esifanayo sokusindisa ugesi ongu-30% ~ 50%; Impuphu ecolekile yempuphu yensimbi ixutshwa ngqo kukhonkolo, okusindisa inani lesimende futhi ngaleyo ndlela konga ukusetshenziswa kwamandla kokukhiqizwa kwesimende. Impuphu, inqubo yokugaya i-slag yensimbi, ingalungisa kalula ubuncane bemikhiqizo ngokuya ngezidingo zemakethe. Ngokwanda kokungezwa kwe-slag ne-slag yensimbi kukhonkolo, ukushisa komswakama kanye nokuqukethwe kwezingxenye eziyingozi zekhonkolo kungancishiswa, okudala izimo ezinhle zokuthuthukisa ukusebenza kwekhonkolo ngokusetshenziswa kwamandla okuphansi. I-slag yensimbi igaywa ngempuphu yokugaya eqondile, futhi izinto zigaywa endaweni enomswakama ekushiseni okuphezulu (100℃ ~ 300℃). Iningi le-calcium oxide yamahhala kanye ne-magnesium oxide yamahhala ku-micro-powder yensimbi ye-slag zifakwa ku-calcium hydroxide esebenzayo kakhulu kanye ne-magnesium hydroxide. Ngaphezu kwalokho, ngenxa yokufakwa kwe-slag kanye ne-steel slag kukhonkolo, ukusabela kwe-alkali aggregate kungancishiswa ngempumelelo, imifantu emincane yekhonkolo ingavinjelwa, futhi isikhathi sokuphila kwezakhiwo singandiswa. Ngakho-ke, ikhonkolo exutshwe ne-slag powder iyamukelwa yimboni yokwakha ngenxa yezakhiwo zayo ezihlukile. I-slag yensimbi yokugaya yodwa ingasetshenziswa njengomkhiqizo wokukhiqiza ikhonkolo nokuxuba ngokwezidingo zemakethe, futhi ingalungiswa ngokwesidingo sokulungisa ubuncane kanye nenani lokuxuba elizohlelwa libe yi-samente yokuthengisa.

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.
