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.
