Lub luag haujlwm ntawm cov hlau ntshiab hauv cov thev naus laus zis thiab kev lag luam
Lub hauv paus rau phau ntawv
Hlau, plaub feem ntau muaj plaub feem ntau muaj nyob hauv ntiaj teb, tau tsim tib neeg kev vam meej rau millennia. Thaum steel-ib tug carbon-hlau alloy-dominates infrastructure thiab kev tsim khoom,Cov Hlau Hlau(Ntau dua los yog sib npaug ntawm 99.8% FE) ua ib qho tseem ceeb tsis tau nkag siab lub luag haujlwm hauv kev lag luam hom kev lag luam zoo thiab kev txhim kho txuj ci keeb kwm. Tsab ntawv no tshawb txog cov qauv tshwj xeeb, cov qauv siv ntau yam, thiab txiav-ntug kev siv cov khoom ntshiab hauv kev tsim kho niaj hnub.
Hlau ntshiab?
Cov Hlau ntshiab yog cov muag muag, ducas hlau nrog cov ntsiab lus carbon minimal (<0.008%) and trace impurities (e.g., sulfur, phosphorus). Unlike steel, it lacks alloying elements, offering distinct characteristics:
Cov Khoom Sib Nqus: Tshwj xeeb permeability thiab kev sib tw qis, zoo tagnrho rau hluav taws xob.
Kev ua siab loj: Yooj yim tsim mus rau hauv cov xov hlau, cov ntawv txheeb, lossis cov duab sib xyaw.
Thermal thiab hluav taws xob conductivity: Surpives feem ntau cov hlau tab sis tsawg dua tooj liab lossis txhuas.
Corrosion Tsis Txaus: Nquag mus xeb tshwj tsis yog muaj kev tiv thaiv, txwv kev siv sab nraum zoov.
Tsim cov hlau ntshiab
Thawj txoj hauv kev
Electrolytic Refining: Hlau ore yog yaj thiab electroplated rau 99.95% purity.
CarbonyL txheej txheem: Hlau nthuav dav nrog cov pa roj carbon monoxide rau cov hlau carbonyl roj, decomposed rau hauv ultra-ntshiab hmoov (99.98% + FE).
Thib ob rov
Yuav kom ua tiav kev coj dawb huv:
Nqus ARC rho tawm (var): Tshem tawm cov roj (o₂, n₂) nyob rau hauv lub tshuab nqus tsev.
Electroslag reacelting (ESR): Molting SLAG kev nqus cov impurities li sulphur thiab oxides.
Thaj chaw ua haujlwm: Tsim 99.999% + Hlau rau Quantum Tshawb Fawb.
Cov qib ntawm cov hlau ntshiab:
Armco Hlau(99.8% FE): Kev tsim kev lag luam thiab txheej.
Cov Hluav Taws Xob Electrolytic(99.95% FE): Kev siv sib nqus thiab tshuaj sib sib nqus.
Carbonyl hlau(99.98% Fe): Cov khoom siv hluav taws xob ntau zaus thiab cov neeg ua kom mob.
