Tsis ntev los no, cov hlau slag hmoov ntau lawm kab nrog cov loj tshaj plaws muaj peev xwm nyob hauv Suav teb tau ua tiav thiab muab tso rau hauv kev ua haujlwm hauv Shagang pawg. Tag nrho kev nqis peev ntawm txoj haujlwm no yog kwv yees li 170 lab yuan, thiab nws tau kwv yees uas 600000 tons ntawm steel slag hmoov yuav raug tsim txhua xyoo. Vim tias lub siab tawv ntawm steel slag, lub particle hla ntawm cov pa pob zeb thiab cov menyuam zeb tseem yuav ua rau Caas ntau dua. TusHlau SlagNtsug Cov Menyuam Zeb yog siv nyob rau hauv cov kab ntau lawm ntawm cov hlau sib ceg ntawm shaagang, uas ncaj qha "omits" inclmoormediate txuas. Lub cheeb tsam hla ntawm tus hlau slag tuaj yeem ncav cuag 0.003mm. Raws li lub hauv paus ntawm kev txo lub zog siv ntawm cov txheej txheem, txhim kho cov khoom siv hluav taws xob ib puag ncig, ntxiv cov khib nyiab "rau" cov khoom lag luam " "Ntawm ib puag ncig kev tiv thaiv cov txiaj ntsig thiab cov nyiaj txiag. Qhov no qhia tau hais tias cov steel slag muaj lub khw muag khoom lag luam zoo. Raws li tus kws tshaj lij steel ntsug cov menyuam zeb, hcMilling (Guilin Hongcheng) yuav qhia cov ntawv thov kev lag luam ntawm cov menyuam yaus slag ntsug.

Hlau Slag Sib Tsootuav txhuv

Nws tau to taub tias "Hlau Kev Sib Tsoo" yog kev tiv thaiv kev lag luam ib puag ncig, thiab tseem ua dua tshiab kev kho mob "ntawm kev ua haujlwm slag. Xyoo 2020, Shagang yuav tsim qhov loj tshaj plaws 3.3 lab tuj cov phiaj xwm Slag kev sib cais, thiab ua tiav 100% kev siv sib cais ntawm kev sib cais, sib tsoo, pas nrig sib tsoo. Thaum kawg ntawm lub Kaum Hlis ntawm tib lub xyoo, ze li 600 tons ntawm steel slag los ntawm shagang tau ua tiav rau daim txhuam cev hloov chaw ntawm Zhangjanang mids txoj kev. Tom qabHlau Slag Sib Tsootuav txhuvCov kab ntau lawm tau muab tso rau hauv kev ua haujlwm, tus hlau slag tau hloov pauv ntawm "cov khoom siv rov qab" rau "ziab", txuas ntxiv txuas ntxiv ntawm cov saw muaj kev lag luam ntsuab. "Txoj kab uas hla yog 6-8 hli, thiab tom qab ntawd peb txuas ntxiv zom lawv nrog cov hlau ntsug thiab cov txiv kab ntxwv sib dhos." Raws li tus kws tshaj lij los ntawm kev ua haujlwm pulverizing ntawm Shagang Cov Khoom Siv Tshiab Co., cov khoom siv hlau nplaum Slag ntau lawm txog 300000 tons hauv kev lag luam tag nrho. Peb cov kab tshiab 600000 TON NTAU LAWM yog ib qho siv rau tag nrho kev lag luam thiab muaj kev pom zoo dua rau kev tsim cov kev lag luam zoo ntawm kev ua lag luam.

Cov kev tshawb fawb ntawm kev txhim kho thiab kev siv cov hlau me me Kev tsim cov micro hmoov lossis composite micro hmoov los ntawm steel slag tuaj yeem tshem tawm qhov sib txawv ntawm cov hlau nplaum shrag. Thaum lub steel slag yog av rau ib qho kev lom zem los ntawmHlau Slag Ntsug Cov Menyuam Zeb, Thaum thaj chaw tshwj xeeb yog ntau dua 400m2kg, cov hlau hlau tuaj yeem tshem tawm mus rau qhov loj tshaj plaws. Rov ua qauv crystal ntawm cov khoom siv tau sib tsoo yog los ntawm ultra-nplua sib tsoo, thiab cov nplaim taws tuaj yeem txhim kho thiab kho cov yam ntxwv ntawm cov yam ntxwv ntawm cov khoom siv rau cov paj tsib hydraulic. 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 qhov yooj yim actator ntawm slag. Cov ntaub ntawv tshiab qhia tau tias txawm hais tias siv cov hmoov av xws li pob zeb ua kom sib xyaw thiab siv cov pob zeb ua kom sib xyaw,% CAO% MGO) / (% Sio2 +% AL2O3) , kwv yees li 0.9 ~ 1.2, yuav txo cov Alkalinity ntawm cov theem ua kua hauv pob zeb ua rau hauv cov pob zeb corrosion ntawm kev txhawb nqa hauv kev ua vaj tse. Tsis tas li ntawd, lub zog cua sov slag yog lub cev vitreous nrog C3As thiab C2MS2 raws li lub ntsiab lus tseem ceeb. Qhov gellability ntawm granulated tawg rauv slag hmoov los ntawm kev tawg ntawm cov qauv vitag viteeous. Cov khoom lag luam hauv dej tsuas tuaj yeem tsim tsuas yog ua raws li kev ua ntawm Ca (Oh) 2. Tus hlau Slag (% Cao) /% Sio2), uas yog txog 1.8 ~ 3.0. Cov zaub mov muaj feem ntau yog C3S, C2S, CF, C3RS2, Ro, thiab lwm yam Cov zaub mov sib ntsib, uas txhim kho cov khoom ua kua Alkalination ntawm cov pob zeb ua kom zoo, nws tuaj yeem siv ua Alkaline Activator ntawm kev ua hmoov av. Cov pob zeb ua xyaw nrog cov hmoov nplej sib xyaw ua ke muaj cov yam ntxwv ntawm lub zog siab hauv lub sijhawm tom qab. Yog li ntawd, steel sib xyaw thiab slag composite tuaj yeem kawm los ntawm txhua lwm yam, thiab kev ua tau zoo tshaj.

Cov txheej txheem ntau lawm ntawm Hlau Slag Ntsug Cov Menyuam Zeb yog ua ke nrog crushing, sib tsoo, kom qhuav thiab cov txheej txheem sib xyaw ua ke, cov txheej txheem me me, cov khoom siv me me tuaj yeem muab tau los ntawm kev kho qhov nrawm ntawm lub Cov hmoov messorrator, cov huab cua txaus tus nqi ntawm cov zeb ntxuam thiab cov kev sib tsoo siab. Nrog kev hloov pauv ntawm kev tsim qauv txhais tau hais tias thiab cov tswv yim thiab cov peev txheej loj zuj zus, uas yog qhov sib npaug ntawm cov kab sib npaug ntawm cov pob zeb kaw zeb. Vim tias nws zoo nyob rau hauv kev ua tau zoo thiab kev siv hluav taws xob, lub kaw lus yuav siv ntau thiab ntau dua. HCMILLING (GUILIN Hongcheng) yog ib qho kev tshaj lij steel ntsug cov menyuam cov menyuam zeb. Peb liHlm steel slagNtsug Cov Menyuam Zeb yog cov khoom siv zoo tshaj plaws los pab cov menyuam yaus lub zeb kom nthuav cov hlau slag hmoov lag luam. Nws tuaj yeem zom steel slag hmoov nrog qhov chaw siab tshwj xeeb ntawm ntau dua 700, txuag ob cov txheej txheem sib tsoo, thiab ua tiav cov hmoov hlau slag nyob rau hauv ib kauj ruam.
