Kub tau fascinated noob neej rau ib-paus xyoo, tsis yog vim hais tias ntawm nws intrinsic nqi, tab sis kuj vim nws stunning luster thiab ci. Txawm hais tias nyob rau hauv cov hniav nyiaj hniav kub, npib los yog cov ntawv thov kev lag luam, kub lub ci ci ua pov thawj nws cov khoom tshwj xeeb. Txawm li cas los xij, kom tau txais qhov ci zoo meej yuav tsum muaj ntau tshaj li polishing; Nws feem ntau muaj cov txheej txheem metallurgical siab heev.Induction Melting Rauv(VIM) yog ib qho txheej txheem zoo li no uas ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo nkauj kub, txhim kho nws qhov zoo nkauj thiab ua haujlwm zoo. Hauv tsab xov xwm no, peb yuav saib yuav ua li cas ua kom kub hnyiab, thiab lub luag haujlwm tseem ceebInduction Melting Rauvua si hauv cov txheej txheem.

Kawm txog kub thiab nws cov khoom

Kub yog cov hlau muaj txiaj ntsig uas paub txog nws txoj kev tiv thaiv corrosion thiab tarnishing. Nws cov qauv atomic tso cai rau nws pom lub teeb zoo nkauj, muab nws cov yam ntxwv luster. Txawm li cas los xij, qhov purity ntawm kub tuaj yeem sib txawv, thiab impurities tuaj yeem ua rau nws cov luster tsis muaj zog. Kub ntshiab (xws li 24 karat kub) yog mos thiab malleable, ua rau nws tsis haum rau niaj hnub siv hniav nyiaj hniav kub. Yog li ntawd, kub yog feem ntau alloyed nrog lwm yam hlau xws li tooj liab, nyiaj, los yog palladium los txhim khu nws durability thaum tuav nws luster.

Qhov tseem ceeb ntawm kub Purity

Lub luster ntawm kub yog ncaj qha ntsig txog nws purity. Impurities tsis tsuas yog cuam tshuam cov xim thiab luster ntawm kub, tab sis kuj nws tag nrho zoo. Piv txwv li, lub xub ntiag ntawm tooj liab tuaj yeem muab kub xim liab, thaum nyiaj tuaj yeem muab xim dawb. Txhawm rau kom tau txais cov xim uas xav tau thiab ci ntsa iab, goldsmiths feem ntau nrhiav kev ua kom zoo nkauj kub kom siab tshaj plaws ntawm purity. Qhov no yog qhov twgInduction Melting Rauvlos ua si.

Dab tsi yogInduction Melting Rauv?

Induction Melting Rauv(VIM) yog cov txheej txheem metallurgical nyuaj siv los yaj thiab ua kom cov hlau zoo nyob hauv ib puag ncig tswj. Cov txheej txheem yuav muab cov hlau tso rau hauv lub crucible thiab cua sov nws siv lub induction kauj. Kev ua haujlwm tag nrho yuav siv qhov chaw hauv lub tshuab nqus tsev, uas tiv thaiv kev sib kis ntawm huab cua thiab txo qis oxidation. Txoj kev no yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov hlau muaj txiaj ntsig xws li kub, raws li nws tso cai rau kev tswj xyuas meej ntawm cov txheej txheem melting thiab muaj pes tsawg leeg ntawm cov khoom kawg.

Induction Melting Rauvtxheej txheem

Kev npaj: Thawj kauj ruam hauv VIM yog npaj kub thiab txhua yam hlau alloy. Cov ntaub ntawv tau ua tib zoo ntsuas thiab ntxuav kom tshem tawm cov kab mob ntawm qhov chaw.

Melting: Muab cov hlau npaj rau hauv lub crucible thiab muab tso rau hauv lub induction kauj. Induction cua sov tsim ib qho chaw electromagnetic uas melts hlau sai thiab sib npaug.

Nqus ib puag ncig: Lub tshuab nqus tsev vacuum yog tsim los tshem tawm cov cua thiab lwm yam roj uas yuav ua rau cov hlau molten. Qhov chaw no yog qhov tseem ceeb rau kev tswj xyuas qhov purity ntawm kub thiab tiv thaiv oxidation.

Alloying: Yog hais tias kub yuav tsum tau alloyed nrog lwm yam hlau, qhov no yog ua thaum lub melting txheej txheem. Kev tswj xyuas qhov kub thiab txias thiab lub tshuab nqus tsev tso cai rau kev sib xyaw ua ke ntawm cov hlau, uas ua rau muaj qhov sib xws.

Casting: Thaum cov kub melted thiab mus txog qhov xav tau muaj pes tsawg leeg, nws yog poured rau hauv pwm los ua kub ingots los yog lwm yam duab. Cov txheej txheem txias kuj tseem raug tswj xyuas kom muaj kev ncaj ncees ntawm cov khoom kawg.

Ua tiav: Tom qab casting, kub yuav dhau los ua cov txheej txheem ntxiv xws li annealing, polishing, thiab electroplating los txhim kho nws cov luster thiab npaj rau cov hniav nyiaj hniav kub lossis lwm yam kev siv.

Cov txiaj ntsig ntawm Vacuum Induction Kub Melting

VIM tsis txwv rau kub; nws tuaj yeem siv los yaj thiab ua kom zoo rau ntau yam hlau. Qhov versatility no ua rau nws yog ib qho kev xaiv txaus nyiam rau cov tuam txhab lag luam uas ua haujlwm nrog ntau yam khoom siv thiab xav tau cov txheej txheem melting txhim khu kev qha.

Yuav ua li cas kom kub ci

ThaumInduction Melting Rauvplays lub luag hauj lwm tseem ceeb hauv refining kub, ntau yam kev ua tiav yuav tsum tau ua kom tiav cov luster zoo meej. Nov yog qee txoj hauv kev ua kom kub ci:

1. Polishing

Polishing yog ib txoj hauv kev zoo tshaj plaws los txhim kho qhov ci ntawm kub. Cov txheej txheem suav nrog kev siv cov khoom siv abrasive kom tshem tawm qhov tsis zoo ntawm qhov chaw thiab tsim kom muaj qhov sib luag, muaj kev cuam tshuam. Jewellers feem ntau siv polishing compounds thiab buffing log kom ua tiav qhov ci siab.

2. Kev ntxuav

Ua ntej polishing, kub yuav tsum tau ntxuav kom tshem tawm cov av, roj, los yog tarnish. Koj tuaj yeem siv cov tshuaj me me ntawm dej sov thiab xab npum me me, tom qab ntawd yaug thiab qhuav nrog cov ntaub mos muag.

3.Electroplating

Rau qee qhov kev siv, kub plating tuaj yeem txhim kho cov luster thiab zoo li cov khoom kub. Cov txheej txheem cuam tshuam nrog txheej txheej hlau nrog ib txheej nyias ntawm kub, muab cov ci ntsa iab thaum txo cov nqi.

4. Rhodium plating

Rhodium plating yog cov txheej txheem nrov siv los txhim kho cov luster ntawm cov kub dawb. Rhodium yog cov hlau uas muaj qhov cuam tshuam zoo heev uas muab lub ntsej muag ci, zoo li daim iav tiav. Cov txheej txheem no tsis tsuas yog txhim kho kev ci ntsa iab xwb tab sis kuj ntxiv cov txheej txheem tiv thaiv khawb thiab tawg.

5. Kev saib xyuas tsis tu ncua

Txhawm rau kom kub ci, kev saib xyuas tsis tu ncua yog qhov tseem ceeb. Qhov no suav nrog kev tu thiab polishing raws li qhov xav tau, nrog rau kev khaws cov khoom kub kom zoo kom tsis txhob khawb thiab puas.

nyob rau hauv xaus

Lub allure ntawm kub nyob tsis tau tsuas yog nyob rau hauv nws cov nqi tab sis kuj nyob rau hauv nws stunning brilliance. Ua kom tiav gloss zoo meej yuav tsum muaj kev sib xyaw ua ke ntawm cov purity siab thiab cov txheej txheem ua tiav zoo.Induction Melting Rauvplays lub luag haujlwm tseem ceeb hauv kev ua kom zoo nkauj kub, ua kom nws mus txog qhov xav tau purity thiab zoo. Los ntawm kev nkag siab txog qhov tseem ceeb ntawm VIM thiab siv cov txheej txheem kev saib xyuas kom raug, txhua tus tuaj yeem txaus siab rau qhov ci ntsa iab ntawm kub rau xyoo tom ntej. Txawm nyob rau hauv cov hniav nyiaj hniav kub, electronics los yog lwm yam kev siv, kub lub luster yeej ib txwm ua ib lub cim ntawm kev zoo nkauj thiab zoo, ua tiav los ntawm advanced metallurgical txheej txheem.
