Taw qhia rau slag
Slag yog cov khoom pov tseg uas tsis suav nrog cov txheej txheem hlau ua.Ntxiv nrog rau cov hlau ore thiab roj, qhov tsim nyog ntawm limestone yuav tsum tau ntxiv los ua lub cosolvent thiaj li yuav txo tau qhov kub thiab txias.Calcium oxide, magnesium oxide thiab khib nyiab ore nyob rau hauv hlau ore tau los ntawm lawv decomposition nyob rau hauv blast furnace, raws li zoo raws li cov tshauv nyob rau hauv coke yog yaj, uas ua rau molten teeb meem nrog silicate thiab silicoaluminate raws li lub ntsiab Cheebtsam, uas ntab rau saum npoo ntawm molten. hlau.Nws raug tso tawm tsis tu ncua los ntawm qhov chaw nres nkoj slag tawm thiab quenched los ntawm huab cua los yog dej los tsim cov granular hais.Qhov no yog granulated blast furnace slag, hu ua "slag".Slag yog ib yam khoom siv nrog "cov khoom muaj peev xwm hydraulic", uas yog, nws yog ib txwm tsis muaj dej thaum nws nyob ib leeg, tab sis nws qhia tias dej hardness nyob rau hauv qhov kev txiav txim ntawm qee cov activators (txiv qaub, clinker hmoov, alkali, gypsum, thiab lwm yam).
Kev siv ntawm slag
1. Slag Portland cement yog tsim los ua raw khoom.Granulated blast furnace slag yog tov nrog Portland cement clinker, thiab ces 3 ~ 5% gypsum yog ntxiv rau sib tov thiab zom kom slag Portland cement.Nws tuaj yeem siv tau zoo dua hauv dej engineering, seaport thiab underground engineering.
2. Nws tuaj yeem siv los tsim slag cib thiab ntub dej dov slag qhob khoom
3. Muab cov dej slag thiab activator (cement, txiv qaub thiab gypsum) rau ntawm lub log zeb, ntxiv dej thiab grind nws rau hauv mortar, thiab ces sib tov nrog ntxhib aggregate los ua ntub dov slag pob zeb.
4. Nws tuaj yeem npaj slag gravel pob zeb thiab siv dav hauv kev tsim kho kev tsim kho thiab kev tsheb ciav hlau.
5.Application ntawm nthuav slag thiab nthuav hlaws nthuav dav slag yog tsuas yog siv los ua lub teeb yuag aggregate los ua lub teeb yuag.

| Kev xaiv khoom siv | Vertical sib tsoo zeb |
Kev tsom xam ntawm kev sib tsoo zeb qauv
Vertical roller mills:
Cov cuab yeej loj loj thiab cov khoom tso tawm siab tuaj yeem ua tau raws li kev tsim khoom loj.Vertical zeb muaj kev ruaj ntseg siab.Disadvantages: cov cuab yeej siv peev nyiaj siab.
Theem I:Crushing ntawm raw khoom
Qhov lojslagcov khoom yog crushed los ntawm lub crusher mus rau lub pub fineness (15mm-50mm) uas tuaj yeem nkag mus rau hauv kev sib tsoo zeb.
TheemII: Gnkim
Lub crushedslagCov ntaub ntawv me me raug xa mus rau lub hopper cia los ntawm lub elevator, thiab tom qab ntawd xa mus rau qhov sib tsoo chamber ntawm lub zeb sib npaug thiab ntau npaum li cas los ntawm feeder rau kev sib tsoo.
Theem III:Muab faibhauv
Cov ntaub ntawv milled tau muab qhab nia los ntawm kev muab qhab nia, thiab cov hmoov tsis tsim nyog tau muab qhab nia los ntawm cov khoom faib thiab rov qab mus rau lub tshuab tseem ceeb rau kev sib tsoo.
TheemV: Collection ntawm cov khoom tiav
Cov hmoov ua raws li kev nplua nuj ntws los ntawm cov raj xa dej nrog cov roj thiab nkag mus rau hauv cov plua plav collector rau kev sib cais thiab sib sau.Cov hmoov uas tau sau tiav yog xa mus rau cov khoom tiav silo los ntawm cov khoom siv thauj khoom los ntawm qhov chaw nres nkoj tawm, thiab tom qab ntawd ntim los ntawm cov hmoov tanker lossis tsis siv neeg ntim khoom.
Daim ntawv thov piv txwv ntawm slag hmoov ua
Qauv thiab tus naj npawb ntawm cov khoom siv no: 1 teeb ntawm HLM2100
Cov khoom siv raw: Slag
