Cov txiaj ntsig ntawm Steel Slag thiab Slag Treatment

Durability
Steel slag yog ib yam khoom nyuaj, ntom ntom ntom uas tiv taus hnav thiab puas. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev tsim kho, qhov twg nws tuaj yeem siv los ua cov khoom siv hauv paus lossis ua ib txheej txheej.

Lub zog
Steel slag muaj lub zog compressive siab, uas txhais tau hais tias nws muaj peev xwm txhawb nqa hnyav. Qhov no ua rau nws tsim nyog siv rau hauv lub hauv paus, roadbeds, thiab lwm yam kev siv load-bearing.

Tus nqi qis
Steel slag feem ntau tsis tshua kim dua li lwm yam khoom siv, xws li pob zeb lossis asphalt, uas ua rau nws muaj kev xaiv zoo rau cov neeg tsim khoom thiab cov neeg cog lus.

Environmental Benefits
Siv steel slag hauv kev tsim kho yuav pab txo qis cov khoom pov tseg uas tsim los ntawm cov hlau ntau lawm, vim nws rov ua dua cov khoom siv uas yuav muab pov tseg. Steel slag kuj yog ib qho kev xaiv ruaj khov dua li lwm cov ntaub ntawv, vim nws xav tau lub zog tsawg dua los tsim thiab muaj cov pa roj carbon tsawg dua.

Tshuaj Stability
Steel slag yog resistant rau tshuaj tua kab mob, uas ua rau nws haum rau siv nyob rau hauv ib puag ncig uas tej zaum yuav raug rau acids los yog lwm yam corrosive tshuaj. Qhov no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv kev lag luam lossis cov chaw tswj cov khib nyiab.

Dab tsi yog Tthe Application of Steel Slag In Building Materials?

Kev siv ntawm steel slag cement

Steel slag slag cement (hu ua steel slag cement) yog raws li steel slag, granulated blast furnace slag raws li lub ntsiab tivthaiv, ntxiv ib tug tsim nyog tus nqi ntawm Portland cement clinker thiab gypsum, sib tsoo los ua hydraulic cementing khoom. Vim tias steel slag cement yog raws li steel slag thiab granulated blast furnace slag ua cov ntaub ntawv tseem ceeb, cov khoom siv no tuaj yeem txuag cov pob zeb limestone, txuag lub zog, txo CO2 thiab cov pa phem rau ib puag ncig, yog li nws tuaj yeem hu ua "ntsuab. cement". Cov hlau slag cement npaj los ntawm kev ntxiv 10% steel slag hmoov rau hauv cov cement clinker muaj zog flexural ntau dua thiab compressive zog dua li cov cement. Steel slag cement tsis tsuas yog muaj lub cev zoo ib yam li Portland cement, tab sis kuj muaj cov yam ntxwv xws li siab lig zog, siab folding zog, zoo permeability tsis kam, zoo hnav tsis kam, micro-expansion, tsis tshua muaj cua sov ntawm hydration, corrosion. tsis kam thiab lwm yam.

Kev siv steel slag hmoov ua ib qho kev sib xyaw

Cov kev tshawb fawb soj ntsuam tau pom tias tom qab ntxiv cov hlau slag hmoov los yog cov khoom sib xyaw steel slag hmoov rau cov pob zeb, qhov khoov lub zog yuav siab dua, kev hnav tsis kam yuav zoo dua, thiab kev ua haujlwm ntawm cov pob zeb sib xyaw tshiab tuaj yeem txhim kho. Hauv particular, nws tuaj yeem txo qhov tshwm sim ntawm lub sijhawm hydration thaum tshav kub kub ncov thiab ncua lub ncov, thiab cov nyhuv yog pom tseeb dua nrog qhov nce ntawm ntau npaum. Tsis tas li ntawd, cov pob zeb ua los ntawm steel slag micro-hmoov muaj cov yam ntxwv ntawm micro-expansion, uas tuaj yeem them nyiaj rau shrinkage thiab txo qhov qhuav shrinkage ntawm pob zeb nyob rau theem tom ntej, thiab tuaj yeem siv dav hauv kev ua haujlwm siab cement qhob admixture. , uas tuaj yeem txhim kho lub cev thiab tshuaj lom neeg ntawm cov pob zeb xws li folding lub zog, hnav tsis kam, dej kub thiab qhuav shrinkage kev ua haujlwm.

Hom Steel Slag Thiab Slag Treatment

Acid Steel Slag
Acid steel slag yog tsim los ntawm kev sib xyaw ntawm cov hlau tsis yog hlau oxides thiab silicates tsim tom qab oxidation thaum lub sij hawm steelmaking. Nws yog nplua nuj nyob rau hauv silicate raws li lub ntsiab tivthaiv thiab muaj tsawg carbon thiab alumina. Acidic steel slag feem ntau yog los ntawm kev hloov pauv smelting txheej txheem ntawm steelmaking. Nws yog tus cwj pwm los ntawm nws cov xim sib zog, xim daj lossis grey, mos zoo nkauj thiab zoo lubrication.

Alkaline Steel Slag
Alkaline steel slag yog ib hom hlau slag uas nws cov khoom tseem ceeb yog cov hlau tsis muaj hlau oxides thiab alkaline hlau oxides uas tsim thaum lub sij hawm thermal tshua xws li hlau-aluminium ore. Hom alkaline steel slag yog tsim los ntawm cov khoom siv smelting xws li hluav taws xob arc rauv, induction furnaces thiab txhaj rauv. Nws yog tus cwj pwm los ntawm cov tsos dub, ntxhib hais, tawv thiab tawv zoo nkauj, thiab siab melting point.

Neutral Steel Slag
Neutral steel slag yog hais txog ib hom tshiab ntawm steel slag tsim los ntawm kev sib xyaw acidic steel slag thiab alkaline steel slag thaum lub sij hawm steel smelting txheej txheem. Qhov nruab nrab steel slag feem ntau yog los ntawm slag tov nrog seem hlau, seem steel, seem steel rings thiab lwm yam ntaub ntawv. Nws cov khoom tseem ceeb yog silicate, calcium silicate thiab ib qho me me ntawm dawb calcium oxide, alumina, thiab lwm yam. Neutral steel slag yog tus cwj pwm los ntawm cov xim sib dua, lub teeb grey lossis xim dawb, nruab nrab zoo nkauj thiab nruab nrab hardness.

Cov khoom ntawm Steel Slag thiab Slag Treatment

Kev paub txog cov tshuaj, mineralogical, thiab morphological ntawm steelmaking slag yog qhov tsim nyog vim lawv cov cementitious thiab mechanical zog ua lub luag haujlwm tseem ceeb hauv nws txoj kev siv. Piv txwv li, cov khoom sib txhuam ntawm steelmaking slag yog cuam tshuam los ntawm nws cov morphology thiab mineralogy. Ib yam li ntawd, lub volumetric stability ntawm lub slag yog ib tug muaj nuj nqi ntawm nws chemistry thiab mineralogy.

Steelmaking slag feem ntau yog calcium alumino silicate. Cov tshuaj no muaj cov ntsiab lus xws li sulfur, selenium, carbon, cadmium, lead, tooj liab, thiab mercury. Feem ntau cov residuals yog encased nyob rau hauv ib tug glassy matrix. Lub matrix yog soluble thiab tso tawm calcium thiab manganese oxides, uas tuaj yeem ua rau kom cov pH ntawm cov kua dej soluble mus rau qib 10 lossis 11. Raws li slag yog iav coarse, nws tswj cov permeability siab (0.045 centimeters ib ob) txawm tias dej ntau npaum li cas los ntawm nws. Lub permeability ntawm slag yog txo thaum nws yog compacted los yog grounded rau hauv me me hais.

Steel Slag Kho Txheej Txheem

Slag Line Hot Splash Method
Cov hlau slag yog tipped, txias los ntawm txau dej rau 3 mus rau 4 hnub, thiab ces feem ntau ntawm cov hlau slag yog tus kheej-decomposed thiab tawg, thiab ces thauj mus rau lub sib nqus sib cais kab rau kev ua. Qhov zoo ntawm cov txheej txheem no yog tias nws tsis muaj qhov tshwj xeeb ntawm lub cev lub cev ntawm lub slag, yooj yim rau kev khiav lag luam, thiab muaj peev xwm ua haujlwm loj.

Slag Span Inner Box Kub Pouring Method
Lub slag tig qhov chaw rau cov txheej txheem no yog lub slag cia tank ua nrog steel billets ntawm peb sab. Lub steel slag tank yog nqa ncaj qha los ntawm steelmaking rhiav mus rau lub slag ncua, tig mus rau hauv lub trough box, thiab ces watered thiab txias. Qhov zoo ntawm cov txheej txheem no yog tias nws nyob hauv thaj chaw me dua li cov kab slag kub, tsis muaj qhov tshwj xeeb rau lub cev lub cev ntawm cov slag, muaj peev xwm ua haujlwm loj, yooj yim rau kev khiav lag luam, thiab muaj nqi tsim kho tsawg dua qhov kub hnyiab. ntaus ntawv.

Txoj Kev Roller
Thaum kub-kub kua steel slag ntws los ntawm lub chute, nws yog crushed los ntawm high-pressure cua, sprayed mus rau ib puag ncig steel baffles, thiab ces poob rau hauv lub pas dej ua ke hauv qab no. Qhov zoo ntawm cov txheej txheem no yog cov txheej txheem luv luv, cov khoom siv me me, qhov chaw hauv pem teb tsawg dua, kev ruaj ntseg zoo ntawm cov hlau slag, granular slag, zoo sib cais ntawm slag thiab hlau, f-CaO cov ntsiab lus hauv slag tsawg dua 4% (qhov loj feem, tib yam hauv qab no ), thiab yooj yim tailing. Kev siv cov slag hauv cov khoom siv hauv tsev.

Txoj Kev Kub Kub
Thaum lub slag kub ib txwm txias mus rau 300-800 degree, ntxeev lub kub steel slag rau hauv lub tank kub, npog lub tank thiab kaw nws. Tom qab soaking rau ib nrab ib teev, tsuag dej rau ntawm steel slag intermittently. Lub thermal stress generated los ntawm ceev ceev ua rau cov hlau slag tawg thiab tawg. Nyob rau tib lub sij hawm, ib tug loj npaum li cas ntawm saturated chav nkag mus rau hauv lub slag thiab undergoes ib tug hydration cov tshuaj tiv thaiv nrog f-CaO thiab f-MgO, uas tsub kom lub zos ntim ntawm cov hlau slag thiab ua rau nws tus kheej-decompose thiab pulverize.

Yuav Ua Li Cas Xaiv Steel Slag thiab Slag Treatment

Kev siv ib puag ncig

Kev siv ib puag ncig ntawm qis-alkaline steel slag plays lub luag haujlwm tseem ceeb hauv kev xaiv cov khoom. Piv txwv li, yog tias qis-alkaline steel slag yog siv rau kev txhim kho pavement, yam xws li nws cov kav ntev thiab dej tsis kam yuav tsum tau txiav txim siab.

Steel Slag yam ntxwv
