Tsis ntev los no, steel slag hmoov cov kab ntau lawm nrog cov peev txheej ntau tshaj plaws hauv Suav teb tau ua tiav thiab muab tso rau hauv kev ua haujlwm hauv Shagang Group.Tag nrho cov peev ntawm qhov project no yog kwv yees li 170 lab yuan, thiab nws kwv yees tias 600000 tons ntawm steel slag hmoov yuav raug tsim txhua xyoo.Vim lub siab hardness ntawm steel slag, particle txoj kab uas hla ntawm cov pa pob zeb thiab cov menyuam zeb tseem yog hais txog 6-8 hli tom qab crushing, uas yuav tsum tau cov cement ntau lawm cov lag luam rov ua dua.Covsteel slagntsug roller mills yog siv nyob rau hauv cov kab ntau lawm ntawm steel slag zeb ntawm Shagang, uas ncaj qha "tawm" qhov nruab nrab txuas.Txoj kab uas hla fineness ntawm steel slag tuaj yeem ncav cuag li 0.003mm.Raws li kev txo qis kev siv hluav taws xob ntawm cov txheej txheem, nws tuaj yeem txo qhov kev puas tsuaj ib puag ncig, txhim kho tus nqi ntxiv ntawm cov khoom, ntxiv txhawb kev hloov pauv ntawm cov hlau slag los ntawm "khoom khib nyiab" mus rau "cov 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 steel slag zeb muaj kev lag luam zoo.Raws li cov kws tshaj lij steel slag ntsug cov menyuam zeb, HCMilling (Guilin Hongcheng) yuav qhia txog kev ua lag luam ntawm steel slag ntsug cov menyuam zeb.

steel slag sib tsoozeb

Nws tau nkag siab tias "steel slag sib tsoo" yog kev lag luam lees paub txog kev tiv thaiv ib puag ncig, kev lag luam rov ua dua tshiab, thiab tseem yog "thib ob" ntawm kev kho steel slag hauv Shagang.Xyoo 2020, Shagang yuav tsim qhov loj tshaj 3.3 lab tuj steel slag kho qhov project hauv Suav teb, thiab ua tiav 100% kev siv steel slag los ntawm kev sib nqus sib nqus, crushing, qws sib tsoo, tshuaj ntsuam thiab lwm yam kev sib sib zog nqus.Thaum kawg ntawm lub kaum hli ntuj ntawm tib lub xyoo, ze li ntawm 600 tons ntawm steel slag los ntawm Shagang tau ntse thov mus rau lub sponge transformation project ntawm Zhangjiagang nroog txoj kev.Tom qab lubsteel slag sib tsoozebCov kab ntau lawm tau muab tso rau hauv kev ua haujlwm, cov hlau slag tau hloov pauv los ntawm "khoom khib nyiab" mus rau "cov khoom", thiab cov khoom siv rov ua dua tau "qhuav thiab nyem", txuas ntxiv txuas ntxiv rau cov saw nyiaj ntsuab ntsuab."Lub cheeb ntawm raw cov ntaub ntawv yog 6-8mm, thiab tom qab ntawd peb ntxiv zom lawv nrog steel slag ntsug cov menyuam zeb, thiab qhov fineness ncav cuag li 0.003mm nyob rau hauv txoj kab uas hla."Raws li cov kws tshaj lij los ntawm pulverizing Rhiav ntawm Shagang New Materials Co., cov pa steel slag ntau lawm kab yog li 300000 tons hauv tag nrho kev lag luam.Peb cov kab tshiab 600000 tuj ntau lawm yog ib qho kev siv rau tag nrho kev lag luam thiab yog qhov tsim nyog rau kev tsim cov qauv kev lag luam zoo.

Kev tshawb fawb txog kev txhim kho thiab kev siv cov hlau slag micro hmoov yog lub ntsiab lus kub tom qab kev siv loj ntawm slag micro hmoov nyob rau hauv xyoo tas los.Kev tsim cov hmoov micro lossis cov hmoov sib xyaw micro los ntawm steel slag tuaj yeem tshem tawm qhov sib txawv ntawm kev sib tsoo hauv kev tsim cov hlau slag cement.Thaum lub steel slag yog av rau ib tug tej yam fineness los ntawmsteel slag ntsug roller mills, thaum thaj chaw tshwj xeeb yog ntau dua 400m2Kg, cov hlau hlau tuaj yeem raug tshem tawm mus rau qhov loj tshaj plaws.Cov qauv siv lead ua ntawm cov khoom yog reorganized los ntawm ultra-zoo sib tsoo, thiab particle deg mob hloov, lub nto yuav txhim kho thiab mechanically txhawb cov kev ua ntawm steel slag, muab kev ua si rau cov yam ntxwv ntawm hydraulic cementing cov ntaub ntawv.Thaum steel slag hmoov thiab slag hmoov yog compounded, lawv muaj qhov zoo ntawm superposition.Calcium hydroxide tsim thaum C3S thiab C2S hauv steel slag yog hydrated yog lub hauv paus activator ntawm slag.Cov ntaub ntawv tshiab tshaj plaws qhia tau hais tias txawm hais tias kev siv cov hmoov slag ua cov khoom sib xyaw ua ke tuaj yeem txhim kho lub zog ntawm pob zeb thiab txhim kho kev ua haujlwm thiab ua haujlwm ntev ntawm cov pob zeb sib xyaw, qhov qis alkalinity ntawm blast furnace slag (% CaO +% MgO) / (% SiO2 +% Al2O3) , txog 0.9 ~ 1.2, yuav txo cov alkalinity ntawm cov kua theem hauv cov pob zeb, ua rau cov yeeb yaj kiab tsis zoo ntawm cov pob zeb ua kom puas (pH <12.4 yog ib qho yooj yim rau kev puas tsuaj), thiab ua rau corrosion ntawm qhov cuab lub zog hauv pob zeb.Tsis tas li ntawd, lub qhov cub tawg slag yog lub cev vitreous nrog C3AS thiab C2MS2 ua cov khoom tseem ceeb.Lub gellability ntawm granulated moj tej tawg rauv slag hmoov los ntawm disintegration ntawm lub slag vitreous qauv.Cov khoom siv dej tsuas tuaj yeem tsim tau raws li kev ua ntawm Ca (OH) 2. Cov hlau slag muaj cov alkalinity siab (% CaO +% MgO) / (% SiO2), uas yog li ntawm 1.8 ~ 3.0.Cov zaub mov no tsuas yog C3S, C2S, CF, C3RS2, RO, thiab lwm yam. Cov fCaO thiab cov ntxhia hauv cov hlau slag tsim Ca (OH) 2 thaum ntsib dej, uas txhim kho cov kua alkalinity ntawm cov pob zeb ua ke, Nws tuaj yeem siv los ua alkaline activator ntawm slag hmoov.Cov pob zeb sib xyaw nrog steel slag hmoov muaj cov yam ntxwv ntawm lub zog siab hauv lub sijhawm tom qab.Yog li ntawd, steel slag thiab slag composite hmoov tuaj yeem kawm los ntawm ib leeg, thiab kev ua tau zoo dua qub.

Cov txheej txheem ntau lawm ntawm steel slag ntsug roller mills yog kev sib tsoo, sib tsoo, ziab thiab hmoov xaiv, uas yog tus cwj pwm los ntawm kev siv hluav taws xob tsawg, kev ua haujlwm zoo sealing, me me hauv pem teb, txheej txheem yooj yim, thiab lwm yam. Qhov yuav tsum tau ua fineness thiab particle loj faib tau los ntawm kev kho cov rotating ceev ntawm lub hmoov concentrator, cua ntws tus nqi ntawm lub tshuab kiv cua thiab kev sib tsoo siab.Nrog rau kev hloov ntawm kev tsim txhais tau tias thiab cov ntsiab lus thiab cov txheej txheem kev paub tab ntau zuj zus, kev nqis peev ntawm cov tshuab ntsug ntsug mills tau txo qis heev, uas yog qhov sib npaug los yog me ntsis siab dua li ntawm cov kaw Circuit Court pob zeb system.Vim nws qhov zoo ntawm kev ua tau zoo thiab kev siv hluav taws xob, lub kaw lus yuav siv ntau dua thiab dav.HCMilling (Guilin Hongcheng) yog cov kws tshaj lij steel slag ntsug cov menyuam zeb.PebHLM steel slagntsug roller mills yog ib qho khoom siv zoo tshaj plaws los pab cov menyuam ntsug ntsug kom nthuav dav steel slag hmoov ua lag luam.Nws tuaj yeem sib tsoo steel slag hmoov nrog rau thaj tsam tshwj xeeb ntawm ntau dua 700, txuag ob txheej txheem ntawm kev sib tsoo ua ntej thiab zaum kawg sib tsoo, thiab ua kom tiav cov hlau slag hmoov hauv ib kauj ruam.
