Yuav ua li cas tswj qhov teeb meem ntawm npuas thiab impurities hauv kev tsim cov iav naj hoom fwj?

Ua kom muaj kev tswj hwm ntawm npuas thiab impurities hauv kev tsim cov iav naj hoom fwj yog qhov tseem ceeb, vim nws cuam tshuam ncaj qha rau qhov zoo thiab zoo nkauj ntawm cov khoom. Cov hauv qab no yog qee qhov kev ntsuas tseem ceeb los xyuas kom meej tias cov teeb meem no raug tswj tau zoo:

I. Tswj npuas

Raw Material Selection thiab Pretreatment:

Xaiv cov khoom siv high-purity iav kom txo cov ntsiab lus ntawm cov pa roj thiab impurities.

Ua kom sib xyaw thiab zom cov khoom siv raw kom ntseeg tau tias cov khoom sib txawv me me, tiv thaiv cov pa roj los ntawm kev raug kaw thaum lub sij hawm melting txheej txheem.

Melting Process Control:

nruj me ntsis tswj lub melting kub thiab lub sij hawm kom ntseeg tau tias lub iav yaj yog tag nrho homogenized.

Siv lub tshuab nqus tsev degassing lossis inert roj tiv thaiv cov txheej txheem kom txo cov roj cov ntsiab lus hauv iav yaj.

Ua kom muaj kev ruaj ntseg hauv cov txheej txheem melting kom tsis txhob muaj qhov kub thiab txias thiab oxidation-txo cov tshuaj tiv thaiv uas tuaj yeem ua rau cov npuas thib ob.

Optimization ntawm txoj kev tsim:

Tsim cov qauv pwm tsim nyog los xyuas kom meej cov iav yaj ntws zoo ib yam hauv cov pwm, txo txoj hauv kev tsim npuas.

Precisely tswj lub siab thiab kub thaum lub sij hawm tshuab los yog nias txheej txheem kom tsis txhob muaj npuas los yog o thaum lub sij hawm tsim.

II. Tswj cov impurities

Purification ntawm Raw Materials:

nruj me ntsis xaiv thiab ntxuav cov ntaub ntawv raw kom tshem tawm cov ntxhia silicate xws li xuab zeb thiab quartz, thiab hlau impurities xws li hlau thiab chromium.

Tsis tu ncua ntxuav thiab tshuaj xyuas cov khoom siv raw khoom kom tsis txhob muaj kab mob.

Kev tswj ib puag ncig ntau lawm:

Khaws lub rooj cob qhia ntau lawm kom huv thiab huv kom tsis txhob muaj plua plav thiab impurity paug.

Lub kaw lus kaw yuav tsum tau siv los tiv thaiv huab cua sab nraud thiab impurities los ntawm kev nkag mus rau qhov chaw tsim khoom.

Kev Kho Cov Khoom Siv Ua Haujlwm:

Tsis tu ncua ntxuav thiab tswj cov pwm thiab cov cuab yeej tsim los tiv thaiv kev hnav thiab qhov khoob khoob uas tuaj yeem ua kom pom cov impurities.

Siv cov roj pwm zoo thiab cov roj nplua nyeem kom ntseeg tau tias cov pwm saum npoo yog du thiab tsis muaj impurities.

Kev soj ntsuam zoo thiab kev tswj xyuas:

Teem ntau cov ntsiab lus soj ntsuam zoo thaum lub sijhawm tsim khoom kom nruj xyuas thiab tshuaj xyuas cov iav yaj, semi-tiav, thiab cov khoom tiav.

Cov cuab yeej tshuaj ntsuam xyuas qib siab thiab cov tswv yim, xws li kho qhov muag tsom iav thiab cov cuab yeej X-ray diffraction, yog siv los txheeb xyuas impurities hauv iav kom raug.

III. Lwm yam kev xav

Kev cob qhia neeg ua haujlwm: Txhim kho cov neeg ua haujlwm paub txog thiab kev cob qhia ntawm cov khoom zoo thiab kev tswj xyuas cov txheej txheem los txhim kho lawv cov kev txawj ua haujlwm thiab kev paub zoo.

Kev Txhim Kho Nruam: Txhim kho cov txheej txheem ntau lawm thiab cov qauv khoom zoo raws li cov neeg siv khoom tawm tswv yim thiab cov ntaub ntawv lag luam kom tau raws li kev lag luam thiab cov neeg siv khoom xav tau.

Yog li, kom ntseeg tau tias kev tswj hwm ntawm npuas thiab impurities hauv kev tsim cov iav naj hoom fwj yuav tsum tau hais txog ntau yam, suav nrog kev xaiv cov khoom siv raw, kev tswj cov txheej txheem melting, tsim cov txheej txheem optimization, ntau lawm ib puag ncig tswj, khoom siv tu, thiab kev soj ntsuam zoo thiab tswj. Ua raws li cov kev ntsuas no yuav pab txhim kho cov khoom zoo thiab kev zoo nkauj, txhim kho cov neeg siv khoom txaus siab thiab kev sib tw ua lag luam.
