Deoxidization yog ib txoj kev siv nyob rau hauv metallurgy kom tshem tawm cov pa oxygen thaum lub sij hawm tsim steel. Hauv kev sib piv, cov tshuaj antioxidants yog siv rau stabilization, xws li hauv kev cia khoom noj. Deoxidation yog qhov tseem ceeb hauv cov txheej txheem steelmaking vim tias oxygen feem ntau cuam tshuam rau qhov zoo ntawm cov hlau tsim.
Ua raws li qhov xav tau, Deoxidizer txhais li cas?
A deoxidizer yog ib qho tshuaj sib xyaw siv hauv cov tshuaj tiv thaiv lossis txheej txheem kom tshem tawm cov pa oxygen. Hauv kev sib piv nrog cov tshuaj antioxidants, cov deoxidizers tsis yog siv rau stabilization thaum lub sij hawm cia tab sis rau kev tshem tawm oxygen thaum lub sij hawm tsim khoom. Deoxidizers Feem ntau yog siv hauv metallurgy, kom txo cov ntsiab lus ntawm oxygen hauv cov hlau.
Tom qab, lo lus nug yog, dab tsi ntxiv rau steel rau deoxidation? Deoxidation ntawm Hlau . Deoxidation yog cov txheej txheem uas tso cai rau kev tshem tawm cov pa ntau dhau los ntawm molten hlau . Deoxidation ntawm hlau feem ntau yog ua los ntawm ntxiv manganese (Mn), silicon (Si), thiab txhuas (Al); Lwm cov deoxidizers siv yog chromium (Cr), vanadium (V), titanium (Ti), zirconium (Zr), thiab boron (B).
Ib yam li ntawd, tib neeg nug, dab tsi yog kev tua hlau siv rau?
Feem ntau tua hlau suav nrog alloy hlau , stainless hlau , kub resisting hlau , hlau nrog cov ntsiab lus carbon ntau dua 0.25%, steels siv rau forgings, qauv hlau nrog cov ntsiab lus carbon ntawm 0.15 thiab 0.25%, thiab qee qhov tshwj xeeb hlau hauv cov pa roj carbon qis. Nws kuj yog siv rau ib yam hlau castings.
Dab tsi yog qhov txawv ntawm kev tua thiab semi-tiav steel?
Ib nrab - tua hlau yog hais txog ib hom hlau alloy compound ntawm hlau thiab carbon uas tau ib nrab deoxidized nrog cov pa roj tsawg tsawg thaum lub sij hawm solidification. Ib nrab - tua hlau nthuav tawm qib siab ntawm homogeneity ntawm qib molecular. Feem ntau, ntau cov pa roj tau hloov zuj zus hauv ib nrab - tua hlau dua li hauv tua hlau.

Dab tsi yog sub account thiab nws siv rau dab tsi?
Ib tug sub account yog ib tug account segregated nested nyob rau hauv ib tug loj account los yog kev sib raug zoo. Cov nyiaj sib cais no yuav muaj cov ntaub ntawv hauv tsev, ntawv xov xwm, thiab lwm yam ntaub ntawv muaj txiaj ntsig lossis muaj cov nyiaj khaws cia hauv kev nyab xeeb nrog lub txhab nyiaj
Dab tsi yog memo thiab nws siv rau dab tsi?
Ib daim ntawv memo (lossis memorandum, lub ntsiab lus "reminder") feem ntau yog siv rau kev sib txuas lus txoj cai, cov txheej txheem, lossis lwm yam kev lag luam hauv lub koom haum
RTM yog dab tsi nws siv rau dab tsi?
Hauv ib txoj haujlwm tsim kho software, Cov Kev Xav Tau Traceability Matrix (RTM) yog ib daim ntawv uas siv los xyuas kom meej tias tag nrho cov kev xav tau txuas nrog rau cov ntaub ntawv xeem. Qhov no yuav pab kom ntseeg tau tias tag nrho cov kev xav tau yuav raug them rau hauv theem kev sim
Cov chiv yog dab tsi thiab lawv siv rau dab tsi?
Cov neeg ua liaj ua teb tig mus rau cov chiv vim tias cov tshuaj no muaj cov khoom noj xws li nitrogen, phosphorus, thiab potassium. Fertilizers tsuas yog cog cov as-ham siv rau kev ua liaj ua teb kom ntxiv cov ntsiab lus uas yuav tsum tau muaj nyob hauv cov av. Cov chiv tau siv txij thaum pib ua liaj ua teb
Dab tsi yog cov khoom siv ncaj qha kev ua haujlwm thiab kev tsim khoom siv nyiaj siv ua haujlwm?
Hauv cov tuam txhab tsim khoom, cov khoom siv nyiaj siv ua haujlwm suav nrog tag nrho cov nqi tsim khoom tshwj tsis yog cov suav nrog cov khoom siv ncaj qha thiab kev ua haujlwm ncaj qha. Cov nqi tsim khoom siv nyiaj siv ua haujlwm yog cov nqi tsim khoom uas yuav tsum tau tshwm sim tab sis tsis tuaj yeem lossis tsis tuaj yeem taug qab ncaj qha rau cov khoom tshwj xeeb tsim
