Tsis ntev los no, cov kab tsim cov hmoov hlau slag uas muaj peev xwm tsim khoom loj tshaj plaws hauv Suav teb tau ua tiav thiab muab tso rau hauv kev ua haujlwm hauv Shagang Group. Tag nrho cov peev txheej ntawm qhov project no yog li ntawm 170 lab yuan, thiab kwv yees tias yuav muaj 600000 tons ntawm cov hmoov hlau slag txhua xyoo. Vim yog qhov nyuaj ntawm cov hlau slag, lub cheeb ntawm cov khoom siv ntawm lub pob zeb ib txwm muaj thiab lub tshuab zeb dov tseem yog li 6-8 hli tom qab tsoo, uas xav tau cov tuam txhab tsim cement kom ua tiav dua. Lubhlau slagntsug roller zeb siv rau hauv kab ntau lawm ntawm lub tshuab zeb hlau slag ntawm Shagang, uas ncaj qha "tso tseg" qhov txuas nruab nrab. Qhov zoo ntawm lub cheeb ntawm cov hlau slag tuaj yeem ncav cuag li 0.003 hli. Raws li kev txo qis kev siv zog ntawm cov txheej txheem, nws tuaj yeem txo qhov kev phom sij rau ib puag ncig, txhim kho tus nqi ntxiv ntawm cov khoom, txhawb nqa kev hloov pauv ntawm cov hlau slag los ntawm "cov khib nyiab khov" mus rau "khoom", thiab ua tiav "kev txhim kho ob npaug" ntawm cov txiaj ntsig kev tiv thaiv ib puag ncig thiab cov txiaj ntsig kev lag luam. Qhov no qhia tau hais tias lub tshuab zeb hlau slag muaj kev cia siab zoo hauv kev lag luam. Raws li tus kws tshaj lij hlau slag ntsug roller mill, HCMilling (Guilin Hongcheng) yuav qhia txog kev siv kev lag luam ntawm cov hlau slag ntsug roller mill.

Nws nkag siab tias "steel slag grinding" yog ib qho project tiv thaiv ib puag ncig uas tau lees paub hauv kev lag luam, ib qho project recyclable economy, thiab tseem yog "thib ob leap" ntawm steel slag kho hauv Shagang. Xyoo 2020, Shagang yuav tsim qhov project kho steel slag loj tshaj plaws 3.3 lab tonnes hauv Suav teb, thiab ua tiav 100% kev siv steel slag los ntawm kev sib cais sib nqus, crushing, rod grinding, screening thiab lwm yam kev ua tiav tob. Thaum kawg ntawm lub Kaum Hli ntawm tib lub xyoo, yuav luag 600 tons ntawm steel slag los ntawm Shagang tau siv rau qhov project hloov pauv sponge ntawm Zhangjiagang txoj kev hauv nroog. Tom qabkev sib tsoo hlau slaglub zebCov kab ntau lawm tau muab tso rau hauv kev ua haujlwm, cov hlau slag tau hloov pauv los ntawm "cov khib nyiab khov" mus rau "khoom", thiab cov peev txheej rov ua dua tshiab tau "qhuav thiab nias", txuas ntxiv mus rau txoj saw hlau kev lag luam ntsuab. "Lub txoj kab uas hla ntawm cov khoom siv raw yog 6-8 hli, thiab tom qab ntawd peb ntxiv lawv nrog cov hlau slag ntsug roller mill, thiab qhov zoo ncav cuag li 0.003 hli hauv txoj kab uas hla." Raws li tus kws tshaj lij los ntawm lub chaw ua haujlwm pulverizing ntawm Shagang New Materials Co., cov kab ntau lawm hlau slag ib txwm muaj li 300000 tons hauv tag nrho kev lag luam. Peb cov kab ntau lawm tshiab 600000 tuj yog qhov siv rau tag nrho kev lag luam thiab yog qhov zoo dua rau kev tsim cov qauv kev lag luam zoo.

Kev tshawb fawb txog kev tsim thiab siv cov hmoov hlau slag micro yog ib qho teeb meem kub tom qab kev siv cov hmoov hlau slag loj heev hauv xyoo tas los no. Kev tsim cov hmoov hlau me me lossis cov hmoov sib xyaw ua ke los ntawm cov hlau slag tuaj yeem tshem tawm qhov sib txawv ntawm kev sib tsoo hauv kev tsim cov cement hlau slag. Thaum cov hlau slag raug zom rau qee qhov fineness los ntawmhlau slag ntsug roller zeb, thaum thaj chaw tshwj xeeb tshaj 400m2Kg, cov hlau hlau tuaj yeem raug tshem tawm mus rau qhov loj tshaj plaws. Cov qauv siv lead ua ntawm cov khoom siv tau rov tsim dua los ntawm kev sib tsoo zoo heev, thiab qhov xwm txheej ntawm cov khoom me me hloov pauv, Qhov chaw tuaj yeem txhim kho thiab ua kom muaj zog ntawm cov hlau slag, muab kev ua si rau cov yam ntxwv ntawm cov ntaub ntawv hydraulic cementing. Thaum cov hlau slag hmoov thiab slag hmoov tau sib xyaw, lawv muaj qhov zoo ntawm kev sib tshooj. Calcium hydroxide tsim thaum C3S thiab C2S hauv hlau slag yog hydrated yog qhov yooj yim activator ntawm slag. Cov ntaub ntawv tshiab qhia tau hais tias txawm hais tias kev siv hmoov slag ua cov khoom sib xyaw ua ke tuaj yeem txhim kho lub zog ntawm cov pob zeb thiab txhim kho kev ua haujlwm thiab kev ua haujlwm ntev ntawm cov pob zeb sib xyaw, qhov alkalinity qis ntawm lub cub tawg slag (% CaO +% MgO) / (% SiO2 +% Al2O3), txog li 0.9 ~ 1.2, yuav txo qhov alkalinity ntawm cov kua theem hauv cov pob zeb, ua rau puas tsuaj rau cov zaj duab xis passive ntawm kev txhawb nqa hauv cov pob zeb (pH <12.4 yooj yim puas tsuaj), thiab ua rau xeb ntawm kev txhawb nqa hauv cov pob zeb. Tsis tas li ntawd, lub cub tawg slag yog lub cev vitreous nrog C3AS thiab C2MS2 ua cov khoom tseem ceeb. Qhov gellability ntawm granulated blast furnace slag hmoov los ntawm kev tawg ntawm cov qauv vitreous slag. Cov khoom Hydration tsuas yog tuaj yeem tsim nyob rau hauv qhov kev ua ntawm Ca (OH) 2. Cov hlau slag muaj alkalinity siab (% CaO +% MgO) / (% SiO2), uas yog li 1.8 ~ 3.0. Cov zaub mov feem ntau yog C3S, C2S, CF, C3RS2, RO, thiab lwm yam. Cov fCaO thiab cov zaub mov nquag hauv cov hlau slag tsim Ca (OH) 2 thaum ntsib dej, uas txhim kho cov kua alkalinity ntawm cov kab ke ua vaj tse, Nws tuaj yeem siv ua alkaline activator ntawm slag hmoov. Cov pob zeb sib xyaw nrog hlau slag hmoov muaj cov yam ntxwv ntawm lub zog siab hauv lub sijhawm tom qab. Yog li ntawd, hlau slag thiab slag composite hmoov tuaj yeem kawm tau los ntawm ib leeg, thiab kev ua tau zoo dua.

Cov txheej txheem tsim khoom ntawm hlau slag ntsug roller zeb yog kev sib xyaw ua ke nrog kev sib tsoo, kev sib tsoo, kev ziab thiab kev xaiv hmoov, uas yog tus cwj pwm los ntawm kev siv hluav taws xob tsawg, kev ua haujlwm zoo sealing, thaj chaw hauv pem teb me me, cov txheej txheem yooj yim, thiab lwm yam. Qhov xav tau fineness thiab qhov loj me ntawm cov khoom me me tuaj yeem tau txais los ntawm kev kho qhov ceev ntawm lub tshuab sib xyaw hmoov, qhov cua ntws ntawm lub kiv cua zeb thiab lub siab sib tsoo. Nrog rau kev hloov pauv ntawm cov qauv tsim thiab cov tswv yim thiab cov txheej txheem thev naus laus zis uas paub tab zuj zus, kev nqis peev ntawm lub tshuab zeb ntsug tau txo qis heev, uas yog qhov sib npaug lossis siab dua me ntsis ntawm lub tshuab zeb pob kaw. Vim nws qhov zoo hauv kev ua tau zoo thiab kev siv hluav taws xob, lub kaw lus yuav raug siv ntau dua thiab dav dua. HCMilling (Guilin Hongcheng) yog lub tshuab zeb hlau slag ntsug. PebHLM steel slagntsug roller zeb yog ib qho khoom siv zoo tshaj plaws los pab lub tshuab zeb ntsug kom nthuav dav kev lag luam hmoov hlau slag. Nws tuaj yeem sib tsoo hmoov hlau slag nrog thaj chaw tshwj xeeb siab dua 700, txuag ob txoj kev sib tsoo ua ntej thiab kev sib tsoo zaum kawg, thiab ua tiav kev tsim cov hmoov hlau slag hauv ib kauj ruam.
