Hauv kev lag luam qib siab -kawg stainless hlau cookware, kev siv tshuab hauv qab yog qhov qhia tau zoo. Nws zoo kawg nkaus ua ke cov kav ntev thiab zoo nkauj ntawm cov hlau tsis muaj steel nrog cov thermal conductivity ntawm txhuas thiab 430 stainless hlau. Txawm li cas los xij, thaum lub sij hawm tsim khoom, peb qhov teeb meem tseem ceeb ntawm kev tsim khoom -kev sib xyaw hauv qab delamination, hauv qab blistering, thiab lub lauj kaub lub cev deformation- teeb meem rau txhua tus thawj tswj kev tsim khoom. Qhov no tsis tsuas yog ua rau cov txiaj ntsig tseem ceeb thiab kev ua haujlwm qis, tab sis kuj ua rau lub npe nrov npe.
Nyob rau hauv qhov tseeb, cov teeb meem no tsis intractable. Lub hauv paus ua rau feem ntau tsis yog nyob rau hauv cov khoom nws tus kheej, tab sis nyob rau hauv cov txheej txheem kev koom tes tseem ceeb -brazing. Qhov tsab xov xwm no yuav delve rau hauv lub hauv paus ua rau thiab qhia yuav ua li cas mus cuag ib tug zoo meej tov los ntawm advanced brazing technology.
I. Hauv -Kev tsom xam qhov tob ntawm lub hauv paus ua rau
1. Composite Bottom Delamination: Bond Failure
Lub hauv paus ua rau: Tsis txaus brazing sib koom ua ke lub zog.
Kev xaiv cov hlau tsis zoo brazing: Tsis zoo brazing wettability (fluidity) tiv thaiv cov hlau muab tub lim los ntawm tag nrho cov qhov sib txawv ntawm qhov sib xyaw hauv qab thiab lub lauj kaub lub cev, tsim kom muaj txiaj ntsig capillary. Interface contamination: Roj, oxides, los yog impurities nyob rau hauv weld nto cuam tshuam lub metallurgical daim ntawv cog lus ntawm lub brazing muab tub lim hlau thiab lub hauv paus hlau, zoo li thov roj rau cov kua nplaum.
Cov txheej txheem tsis raug: Cov cua kub tsis txaus lossis lub sijhawm cua sov tiv thaiv lub brazing muab tub lim hlau los ntawm tag nrho melting thiab ntws; Kev kub siab heev tuaj yeem ua rau cov hlau muab tub lim kom hlawv lossis tsim cov khoom sib txuas nrog lub hauv paus hlau.
2. Hauv qab hlwv
Lub hauv paus ua rau: Gas tau daig ntawm cov txheej txheem sib xyaw thiab lub lauj kaub lub cev thaum lub sijhawm vuam, nthuav dav vim yog cua sov thiab tsim cov bulges.
Kev huv tsis txaus: Microscopic noo noo thiab roj vaporize sai ntawm qhov kub thiab txias.
Tsis txaus los yog tsis sib xws: Lub siab tsis txaus siv thaum lub sij hawm vuam kom tshem tawm cov pa roj thiab cov khoom siv hlau ntau dhau los ntawm cov seam brazing.
Flux teeb meem: Tsis zoo los yog tsis zoo daim ntawv thov ntawm flux (yog tias siv) tuaj yeem ua rau cov roj seem hauv lub sijhawm tshem cov yeeb yaj kiab.
3. Lub lauj kaub lub cev deformation: tsis sib xws thermal stress
Keeb kwm:Tsis sib xws cua sov ntawm lub workpiece thaum lub sij hawm vuam ua rau muaj kev ntxhov siab nyob rau hauv, uas yog ces tso tawm thaum txias, ua rau deformation.
Cua sov tag nrho:Siv cov txheej txheem cua sov tag nrho xws li lub tshuab hluav taws xob vuam, ua kom tag nrho lub lauj kaub rau qhov kub siab, ua rau tsis sib xws thaum lub sijhawm txias.
Tsis zoo Heat Source Concentration:Lub tshav kub tsis tuaj yeem tsom ntsoov rau qhov chaw vuam, ua rau lwm qhov ntawm lub lauj kaub kom sov.
II. Hauv paus-Cause Solution: Advanced Brazing Technology
Lub hauv paus tseem ceeb rau kev daws cov teeb meem saum toj no yog nyob rau hauv kev siv cov khoom siv hluav taws xob zoo tshaj plaws, kev siv lub tshuab brazing. Cov thev naus laus zis niaj hnub, xws li siab - zaus induction brazing tshuab thiab lub tshuab nqus tsev brazing, muab cov kev daws teeb meem zoo meej.
Siab -Frequency Induction Brazing Tshuab- Sib npaug Efficiency thiab Precision: Yuav daws qhov teeb meem li cas?
1. Precise Temperature Control: PLC system precisely tswj cua sov lub zog thiab lub sij hawm, xyuas kom meej tias cov khoom brazing melts thiab ntws nyob rau hauv lub optimum kub ntau yam, tsim ib tug muaj zog metallurgical daim ntawv cog lus.
2. Ceev ceev hauv zos cua sov: Lub induction eddy tam sim no yog concentrated tsuas yog nyob rau hauv lub weld cheeb tsam nyob rau hauv qab ntawm lub lauj kaub, tsom lub zog, ua kom txaus brazing wetting, thiab ua rau cov pob qij txha muaj zog heev.
Yuav daws qhov teeb meem Blistering li cas?
Integrated Pressure System: Cov cuab yeej tau nruab nrog cov cuab yeej hydraulic clamping uas siv tas li, lub siab tsis sib xws rau hauv qab sib xyaw thaum lub sijhawm vuam, tshem tawm cov cua tawm ntawm lub brazing seam thiab xyuas kom nruj haum ntawm txheej txheej thiab lub lauj kaub lub cev.
Yuav daws Deformation li cas?
Thaum tshav kub kub tsawg heev-Qhov cuam tshuam: "cov nyhuv ntawm daim tawv nqaij" ntawm siab- zaus cua sov txhais tau hais tias cov cua sov yog siv rau ntawm ib txheej nyias nyias ntawm lub lauj kaub hauv qab, thaum lub lauj kaub tag nrho lub cev tseem nyob ntawm qhov kub thiab txias. Qhov no hauv paus tshem tawm deformation los ntawm thermal stress.
III. Cov kev coj ua zoo tshaj plaws: Cov txheej txheem zais cia uas tshaj cov khoom siv
Txawm tias cov cuab yeej siv siab tshaj plaws yuav tsum muaj cov txheej txheem tshawb fawb. Nov yog ob peb lub tswv yim los xyuas kom meej cov txiaj ntsig tsis zoo:
1. nruj Pre-kev kho mob: Ua ntej welding, lub lauj kaub lub cev thiab cov hauv qab yuav tsum tau muab ntxuav kom huv si thiab degreased kom ntseeg tau tias muaj kev sib txuas ntawm weld.
2. Kev Tsim Kho Kev Tshawb Fawb: Cov khoom siv kho kom haum tsis yog tsuas yog muab lub siab xwb tab sis kuj tseem qhia cov cua sov faib thiab pab hauv qhov chaw, ua kom cov txiaj ntsig zoo ib yam . 3. Sib piv cov brazing muab tub lim hlau rau cov khoom siv hauv paus: Xaiv lub brazing muab tub lim hlau uas sib haum nrog ob qho tib si stainless hlau thiab txhuas (los yog tooj liab), xws li npib tsib xee {{2}c raws, los yog nyiaj ua ntej. ua ntej- teeb lub nplhaib kom paub meej tias qhov ntau npaum li cas.
Fragmentation, blistering, thiab deformation ntawm composite bottoms tsis insurmountable obstacles nyob rau hauv stainless hlau cookware ntau lawm. Lawv yog qhov tseem ceeb tshwm sim ntawm qhov tsis sib haum xeeb ntawm cov txheej txheem vuam ib txwm muaj, cov txheej txheem vuam tsis tu ncua thiab siab - cov kev xav tau zoo. Los ntawm kev hloov kho mus rau qhov tsis siv neeg, meej, siab - zaus induction tov, koj tuaj yeem tsis tsuas yog tshem tawm cov kev mob tshwm sim no thiab txhim kho cov khoom lag luam thiab kev ua tau zoo, tab sis kuj tseem ua rau siab tshaj -kawg cookware nrog cov qauv ruaj khov dua, kev siv hluav taws xob ntau dua, thiab kev ua kom zoo dua qub, yog li tsim kom muaj kev sib tw ua lag luam zoo.
Nrog 15 xyoo ntawm kev paub tob hauv kev lag luam me me, Davinci boasts qhov tshwj xeeb dual kom zoo dua: peb yog ob qho tib si kev paub txog cov khoom siv me me thiab cov chaw tsim khoom siv tshuab. Txawm hais tias nws yog lub rhaub dej kub phaj brazing, lossis stainless hlau cookware hauv qab brazding, peb muaj kev paub dhau los thiab kev daws teeb meem.
Nrog peb cov kws tshaj lij thev naus laus zis brazing rau kev daws teeb meem rau koj cov kev sib tw hauv qab ntau lawm!
