1. Cov xwm txheej tam sim no ntawm kev siv cov hlau slag:

Hlau slag hmoov tau ntev tau suav nrog hauv lub teb chaws qauv raws li kev sib xyaw ua ke. Muaj ntau cov kev sib piv tau ua pov thawj tias: Thaum muaj qee cov hmoov av tshwj xeeb yog ntau dua 420m2 / kg, nws txoj haujlwm zoo ib yam li cov cua sov slag. Qhov sib xyaw sib xyaw ntawm cov hlau ua hmoov av thiab cov hmoov uas tsis muaj txiaj ntsig ntawm cov hmoov sib xyaw ua ke ntawm cov hmoov av los ua kom muaj kev ua tau zoo, yog li ntxiv txo qhov kev npaj tus nqi ntawm kev ua vaj tse. Nws tuaj yeem pom tseeb tias txo cov shrinkage deformation ntawm binder thiab txhim kho cov tawg tsis kam ntawm phau ntawv no. Qhov no qhia tau tias cov khoom lag luam slag hmoov txhuas muaj kev lag luam zoo. Tam sim no, lub ntim ruaj khov ntawm steel slag yog txo vim muaj lub hav zoov ntawm Cao qab dawb thiab Mgo. Cov ntsiab lus siab dua ntawm cov hlau oxide nce qhov nyuaj ntawm kev sib tsoo, lub zog hluav taws xob ntau ntawm tev hmoov av, thiab qhov nyuaj ntawm kev ua steel slag hmoov. Yog li ntawd, cov muag ntim ntim ntawm steel slag hmoov ua lag luam yog me me, uas tseem ua rau cov hlau sluag hmoov ua kev lag luam tawm.

2. Pob zeb ua kom sib xyaw muab qhov chaw rau kev siv cov hlau tshiab steel slag sib tsoo:

Pob zeb sib xyaw ua ke yog qhov kev hloov pauv loj hauv hom kev tsim kho, thiab kev sib sau ua ntu zus los ntawm cov qib ntawm cov qhob qhob ntau hauv lub teb chaws. Kev xyaum ua tau pom tias kev siv cov pob zeb sib tov tau ntau dua li ntawm 5%, thiab tuaj yeem txuag cov chaw tsim khoom zoo dua li 10% 15%, txo cov av muaj kuab, txo cov av qias, yog li ntawd Ua tiav ntsuab tsim kho. Kev txhim kho ntawm kev ua lag luam qhob laj kab ntawm kev sib deev ntawm slag hmoov ntau thiab nthuav qhov kev thov kev lag luam ntawm cov hmoov nplej. Tuam Tshoj npaj ua vaj tse sib xyaw ua ke tau tsim kho ntawm kev tsim kho ntawm Shanghai, tshwj xeeb yog vim muaj kev tsim kho nrawm nrawm Cov cai tswjfwm kev txhawb nqa thiab kev ntsuas coj los ntawm cov tub ceev xwm, yog li lub nroog npaj ua kom nce ntxiv los ntawm 15% ib xyoos. Vim tias tus nqi ntawm slag thiab steel slag thiab pob zeb sib xyaw nrog sluag thiab sib xyaw ua ke thiab haum rau hauv kev sib xyaw ua lag luam ua lag luam. Cov pob zeb ua los ntawm sib xyaw slag thiab steel slag nrog cov xis nyob, cov xuab zeb daj uas muaj qhov zoo thiab cov zog ua haujlwm zoo nrog cov hlau tuav. Nws yog qhov tshwj xeeb tshaj yog tsim nyog rau high-aws, tshav dav hlau, cov hauv paus loj loj thiab cov dej hauv qab. Tam sim no, ultra-siab lub zog qhob yog tsuas yog npaj los ntawm kev sib xyaw ua ke silica tshauv thiab cov khoom siv dej ua ke dej thiab cov txiaj ntsig siab dej txo tus neeg sawv cev. Nrog rau cov siab dua thiab siab dua rau cov yam ntxwv ua si hauv cov phiaj xwm tshwj xeeb tau qhib kev lag luam dav dav rau kev ua kom dav dav thiab hlau slag thiab hlau hmoov. Tib neeg txoj kev nkag siab txog tus yam ntxwv ntawm kev swb thiab steel slag hmoov, ib cov khoom tshiab hauv tsev, kuj yog kev nqus. Nrog rau kev txhawb nqa thiab siv cov khoom lag luam hauv lub tebchaws thiab cov khoom lag luam hauv tebchaws uas cuam tshuam nrog rau cov chaw tsim khoom hauv tebchaws hauv nroog, kev ua lag luam ntawm Slag thiab Hlau Hmoov av yuav muaj ntau thiab ntau dua, thiab nws siv yuav nyiam ntau dua thiab ntau dua.

3. Cov txheej txheem npaj thiab khoom siv ntawm kev sib tsoo me me

Tam sim no, qhov kev sib tsoo tshuab sib tsoo yog siv los zom steel slag-hmoov clinker, uas belongs rau cov kev siv tshuab ntau lawm hauv kev lag luam. Yav dhau los, feem ntau swb slag, steel slag thiab MAAs clinker, gypsum, thiab lwm yam ua ntu zus ntawm kev sib tsoo ntau lawm ntawm cov cement. Vim tias cov khoom noj uas tsis zoo ntawm slag thiab steel slag, kev sib tsoo tsis tuaj yeem tsim tau zoo heev, thiab cov nyiaj tsis tau muaj kev sib xyaw thiab cov khoom siv sib xyaw ua ke tau txwv rau qee yam. Nyob rau hauv kev npaj ntawm ultrafine hmoov los ntawm steel slag ib leeg, Jiangsu hlau thiab hlau qhauj yog nyob rau ntawm lub xub ntiag. Ob peb steel qhauj tawm tsam los ntawm Changzhou Zhongtian hlau thiab hlau tau tsim tshwj xeeb steel slag ntsug txheej txheem cov kab ntau lawm. Raws li tus hlau slag micro-hmoov ntsug zeb chaw tsim tshuaj paus kev lag luam nyob rau hauv ultrafine slag sib tsoo cov txheej txheem thiab cov kab ntsug zeb khoom tsim. Nws cov yam ntxwv tswv yim yog feem ntau cov hauv qab no: kev xaiv ntawm ntsug zeb sib tsoo cov yam ntxwv, muaj zog txhim kho, muaj zog txhim kho, muaj kev txhim kho ntau sab ntawm 400M2 / kg Slag, hlau slag hmoov, tshaj li cov tsoos npas zeb ntau lawm, sib zog nqus cov hmoov tib yam txuag hluav taws xob 30% ~ 50%; Cov hmoov zoo ntawm kev swb thiab cov hlau slag yog ncaj qha sib xyaw, uas txuag tau cov cement thiab yog li txuag hluav taws xob ntawm cov cement. Slag, hlau slag sib tsoo cov txheej txheem, tuaj yeem hloov kho lub txiaj ntsig ntawm cov khoom raws li kev xav tau kev lag luam. Nrog rau kev nce ntawm kev ntxiv ntawm sluag thiab steel slag thiab cov ntsiab lus ntawm cov kev phom sij tuaj yeem raug txo kom tau cov kev ua tau zoo ntawm cov pob zeb uas muaj zog siv hluav taws xob. Tus Hlau Slag yog av los ntawm Ntsug Sib Tsoo Hmoov, thiab cov khoom yog av nyob rau hauv ib puag ncig huab cua ntawm qhov kub (100 ℃ ~ 300 ℃). Feem ntau ntawm cov dawb calcium oxide thiab dawb magnesium oxide nyob rau hauv lub steel slag hydrocide thiab magroxide thiab magroxide. Tsis tas li ntawd, vim muaj kev suav nrog ntawm slag thiab steel slag thiab cov tshuaj tiv thaiv ntawm cov pob zeb ua tau zoo tuaj yeem tiv thaiv tau, thiab lub neej ntawm cov tuam tsev tuaj yeem txuas ntxiv. Yog li ntawd, qhob sib xyaw nrog cov hmoov uas tsis zoo los ntawm kev tsim kho kev tsim kho rau nws cov khoom tshwj xeeb. Sib tsoo cov kab sib tsoo hlau ib leeg tuaj yeem siv los ua cov khoom lag luam thiab kuj tseem tuaj yeem hloov kho kom zoo nkauj thiab sib xyaw ua ke yuav tsum tau teeb tsa ua cov cement rau kev muag khoom.
