1. Tam sim no qhov teeb meem ntawm kev siv cov hlau slag:

Steel slag hmoov tau ntev tau suav nrog hauv lub teb chaws tus qauv raws li cov cement sib tov.Ntau qhov kev sib piv tau ua pov thawj tias: Thaum qhov chaw tshwj xeeb ntawm cov hlau slag hmoov yog ntau tshaj 420m2 / kg, nws cov dej num zoo ib yam li cov blast furnace slag.Kev sib xyaw ua ke ntawm steel slag hmoov thiab slag hmoov tuaj yeem tsis tsuas yog txhim kho qhov kev faib ua feem ntawm steel slag hmoov nyob rau hauv cov hmoov sib xyaw, tab sis kuj nce qhov hloov pauv ntawm cov hmoov sib xyaw rau cov cement raws li kev ua haujlwm ntawm cov pob zeb, ntxiv rau. txo tus nqi npaj ntawm pob zeb.Nws tuaj yeem pom tseeb txo qhov shrinkage deformation ntawm cov ntawv khi thiab txhim kho qhov tawg tsis kam ntawm cov ntawv khi.Qhov no qhia tau hais tias steel slag hmoov cov khoom muaj kev lag luam zoo.Tam sim no, lub ntim ruaj khov ntawm steel slag raug txo vim muaj cov dawb CaO thiab MgO.Cov ntsiab lus siab dua ntawm cov hlau oxide nce qhov nyuaj ntawm kev sib tsoo, kev siv zog ntau dua ntawm cov hmoov slag hmoov, thiab qhov nyuaj ntawm kev ua cov hlau slag hmoov.Yog li ntawd, kev muag khoom ntawm steel slag hmoov ua lag luam yog me me, uas kuj ua rau steel slag hmoov ua ib qho kev lag luam tawm tshiab los tsim.

2. kev sib xyaw ua ke muab qhov chaw rau kev siv ultrafine steel slag sib tsoo:

Kev sib xyaw ua ke hauv nruab nrab yog ib qho kev hloov pauv loj hauv kev tsim qauv ntawm cov phiaj xwm kev tsim kho, thiab qhov kev faib ua feem ntawm kev npaj sib xyaw ua vaj tse kos npe rau theem ntawm kev tsim ua vaj tse hauv lub tebchaws.Kev xyaum qhia tau hais tias kev siv cov pob zeb sib xyaw ua ke tuaj yeem ua rau cov khoom tsim tau ntau dua ob npaug, txuag cov cement 10% ~ 15%, txo cov nqi ntawm qhov project txog 5%, thiab tuaj yeem ua kom tiav qhov project zoo, txuag av tsim kho, txo cov plua plav paug. ua tiav kev tsim kho ntsuab.Txoj kev loj hlob ntawm kev lag luam pob zeb txhawb kev tsim cov slag hmoov ntau lawm thiab nthuav cov kev xav tau ntawm cov hmoov slag.Tuam Tshoj txoj kev npaj sib xyaw ua ke cog cog tau tsim nyob rau xyoo 1980s, pib hauv Shanghai, Jiangsu thiab lwm qhov chaw, vim muaj kev nthuav dav ntawm kev tsim kho, tshwj xeeb tshaj yog vim muaj kev loj hlob sai ntawm kev tsim kho ntawm cov nroog ntug dej hiav txwv sab hnub tuaj, ua ke nrog ib qho kev nthuav dav ntawm kev tsim kho. series ntawm kev txhawb nqa txoj cai thiab kev ntsuas los ntawm kev tsim kho cov tub ceev xwm, kom lub nroog npaj txhij-sib xyaw ua ke nce 15% hauv ib xyoos.Vim tias tus nqi ntawm slag thiab steel slag qis dua li ntawm cov cement, pob zeb sib xyaw nrog slag thiab steel slag yog kev lag luam thiab tsim nyog siv rau hauv kev lag luam sib xyaw ua ke.Cov pob zeb ua los ntawm kev sib xyaw cov slag thiab steel slag nrog cov cement, pob zeb thiab cov xuab zeb daj muaj qhov zoo ntawm lub zog siab lig, tsis tshua muaj dej kub, zoo hnav tsis kam thiab siab sib txuas nrog steel tuav.Nws yog qhov tshwj xeeb tshaj yog tsim rau cov tsev siab siab, DAMS, tshav dav hlau, cov hauv paus tob tob thiab cov dej num hauv qab dej.Tam sim no, ultra-high lub zog pob zeb yog npaj los ntawm kev sib xyaw silica tshauv thiab cov dej ua haujlwm siab txo tus neeg saib xyuas, tab sis tsis muaj silica ash raw cov ntaub ntawv thiab cov dej ua haujlwm siab txo tus neeg saib xyuas yog kim, ua rau cov nqi siab ntawm cov pob zeb.Nrog rau cov kev xav tau siab dua thiab siab dua rau cov yam ntxwv ntawm cov pob zeb loj hauv cov haujlwm tshwj xeeb loj, qhov kev thov ntau ntxiv rau kev lag luam pob zeb tau qhib rau kev lag luam dav dav rau kev siv cov slag thiab steel slag hmoov.Tib neeg txoj kev nkag siab ntawm cov yam ntxwv ntawm slag thiab steel slag hmoov, cov khoom siv hauv tsev tshiab, kuj tseem tob zuj zus.Nrog rau kev txhawb nqa thiab kev siv cov pob zeb ua lag luam hauv lub tebchaws thiab kev siv lub teb chaws cov qauv cuam tshuam nrog cov khoom siv slag thiab steel slag hmoov, thiab kev siv cov cai xws li nruj me ntsis txwv tsis pub sib xyaw ua vaj tse ntawm cov chaw tsim kho hauv nroog, kev ua lag luam ntawm slag thiab steel. slag hmoov yuav ntau thiab ntau dua, thiab nws siv yuav nyiam ntau thiab ntau xim.

3. cov txheej txheem kev npaj thiab cov khoom siv ntawm steel slag micro-powder ntsug sib tsoo tau nrov thiab siv

Tam sim no, ntsug sib tsoo tshuab yog siv los grind steel slag micro-hmoov thiab tsim cov khoom uas hloov high-zog cement clinker, uas belongs rau cov advanced ntau lawm technology nyob rau hauv kev lag luam.Yav dhau los, feem ntau yog slag, steel slag thiab cement clinker, gypsum, thiab lwm yam ua ke, raws li ib feem ntawm kev sib tsoo rau hauv kev sib tsoo ntawm cov cement.Vim tias qhov tsis zoo ntawm cov slag thiab steel slag, kev sib tsoo tsis tuaj yeem ua rau hauv av zoo heev thaum sib xyaw nrog cov cement clinker, nws qhov kev ua tau zoo tsis tuaj yeem tsim tau tag nrho, thiab cov nyiaj thiab daim ntawv thov ntawm slag thiab steel slag raug txwv rau qee yam.Hauv kev npaj cov hmoov ultrafine los ntawm steel slag ib leeg, Jiangsu hlau thiab steel tuam txhab yog nyob rau hauv pem hauv ntej.Ntau lub tuam txhab steel sawv cev los ntawm Changzhou Zhongtian Hlau thiab Hlau tau tsim tshwj xeeb steel slag ntsug sib tsoo txheej txheem ntau lawm kab.Raws li steel slag micro-hmoov ntsug zeb chaw tsim tshuaj paus, HCM Machinery muab kev pab cuam nyob rau hauv lub ultrafine steel slag sib tsoo txheej txheem txoj kev thiab tseem ceeb ntsug zeb khoom tsim.Nws cov yam ntxwv tshwj xeeb yog cov hauv qab no: kev xaiv ntsug zeb sib tsoo steel slag hmoov, nrog cov thev naus laus zis siab, txhim khu kev qha ntau lawm, cov yam ntxwv ua haujlwm siab, nrog ntsug zeb los tsim ib tuj ntawm thaj chaw tshwj xeeb ntawm 400m2 / kg ~ 500m2 / kg slag, steel slag hmoov, dua li cov tsoos pob zeb ntau lawm ntawm tib qhov hnyav ntawm hmoov txuag hluav taws xob 30% ~ 50%;Cov hmoov zoo ntawm slag thiab steel slag yog ncaj qha sib xyaw rau hauv pob zeb, uas txuag cov nyiaj ntawm cov cement thiab yog li txuag lub zog noj ntawm cov cement ntau lawm.Slag, steel slag sib tsoo txheej txheem, tuaj yeem hloov kho qhov zoo ntawm cov khoom raws li kev lag luam xav tau.Nrog rau kev nce ntxiv ntawm slag thiab steel slag hauv pob zeb, hydration tshav kub thiab cov ntsiab lus ntawm cov khoom tsis zoo ntawm cov pob zeb yuav raug txo kom tsawg, uas ua rau muaj kev pom zoo rau kev txhim kho kev ua tau zoo ntawm pob zeb nrog qis zog noj.Cov hlau slag yog hauv av los ntawm ntsug sib tsoo hmoov, thiab cov khoom yog hauv av nyob rau hauv ib qho chaw ntub dej ntawm qhov kub siab (100 ℃ ~ 300 ℃).Feem ntau ntawm cov dawb calcium oxide thiab dawb magnesium oxide nyob rau hauv steel slag micro-hmoov yog hydrated rau hauv siab heev calcium hydroxide thiab magnesium hydroxide.Tsis tas li ntawd, vim muaj cov slag thiab steel slag nyob rau hauv cov pob zeb, cov tshuaj tiv thaiv ntawm alkali aggregate tuaj yeem txo tau zoo, micro-cracks ntawm pob zeb tuaj yeem tiv thaiv, thiab lub neej ntawm cov tsev yuav txuas ntxiv mus.Yog li ntawd, pob zeb sib xyaw nrog slag hmoov yog txais tos los ntawm kev tsim kho kev lag luam rau nws cov khoom tshwj xeeb.Sib tsoo steel slag ib leeg tuaj yeem siv los ua cov khoom ua vaj tse thiab sib xyaw ua ke raws li kev xav tau ntawm kev ua lag luam, thiab tuaj yeem hloov kho raws li qhov xav tau los kho qhov zoo thiab qhov sib xyaw kom haum rau hauv cov cement muag.

Iron and steel enterprises can take advantage of the existing regional location of steel mills, and the source of raw materials is fully guaranteed; The steel mill has advanced and strict scientific management experience, and has experienced technical team and staff team, which provides the guarantee of organization, technology and production management for the implementation of the project and market development; Steel plant power supply, water supply source reliable, convenient transportation, good cooperation conditions, construction conditions are very superior. To sum up, the construction of steel slag micro-powder projects in iron and steel enterprises can not only turn waste into treasure, improve the added value of steel making, create considerable economic benefits for iron and steel enterprises, but also protect the environment, in line with the policy direction of steel and cement industry structural adjustment. The development of steel enterprises layout steel slag powder project is a good thing to benefit the country and the people, has a broad future and is of great significance, and will play a positive role in promoting the construction of "waste free city" and promoting the sustainable development of the steel industry.
