1.Dab tsi yog qhov sib txawv ntawm qhov tseeb qhov tseeb?
Txias-rolled coils: Qhov no yog ib qho ntawm lawv qhov zoo tshaj plaws. Txias dov yog chav sov - txheej txheem ua tiav tom qab kub dov. Los ntawm ntau qhov tseeb dov dhau, nruj heev tuab kam rau ua tswj tau tiav (piv txwv li, los ntawm ± 0.1mm txog ± 0.03mm lossis txawm me dua). Dav thiab flatness (flatness) kuj raug tswj kom nruj, ua rau cov npoo zoo nkauj thiab tiaj tus.
Kub-rolled coils: Rolled ntawm qhov kub siab, txawm hais tias niaj hnub siv tshuab tau zoo heev, lawv cov thickness kam rau ua (xws li, ± 0.2mm0.5mm) thiab flatness tswj yog tseem nyob deb inferior rau txias -rolled coils. Ntug tej zaum yuav irregularly nkhaus (wavy), thiab tsis sib xws thickness thaum pib thiab xaus yog ntau pronounced.
2.Dab tsi yog qhov txawv ntawm qhov chaw tiav?
Txias-rolled coils: Nto zoo yog lwm yam tseem ceeb. Tom qab kub dov, cov nplai oxide raug tshem tawm los ntawm pickling, ua raws li los ntawm txias dov, ua rau ib tug du thiab uniform nto. Qhov sib txawv ntawm qhov roughnesses tuaj yeem dov raws li qhov xav tau (xws li, BA nto yog ze rau daim iav tiav, 2B nto yog xim matte). Nws yog qhov nyiam substrate rau kev kho mob zoo xws li electroplating, xim txheej, thiab siab - zoo txau.
Kub-rolled coils: Qhov saum npoo yog npog nrog ib txheej ntawm xiav - grey hlau oxide nplai, uas yog ntxhib thiab muaj cov pores microscopic. Txawm hais tias nws tuaj yeem raug ntxuav los ntawm pickling lossis tua blasting (ua "pickled coils"), nws qhov smoothness thiab uniformity tseem tsis tuaj yeem piv nrog txias -rolled coils. Nws feem ntau tsis siv ncaj qha rau qhov pom qhov pom.
3.Dab tsi yog qhov txawv ntawm kev ua thiab kev tsim precision?
Txias-rolled coil:
Siab sib xws: Cov khoom siv sib xws thiab cov tuab ruaj khov ua rau muaj qhov zoo sib xws thaum lub sij hawm nruam stamping thiab dabtsi yog khoov.
Tsawg thiab tswj tau lub caij nplooj ntoos hlav: Vim nws lub zog siab thiab tsis sib xws, lub caij nplooj ntoos hlav rov qab tau yooj yim dua los kwv yees thiab them nyiaj rau lub sijhawm raug khoov.
Tsim nyog rau txoj kev sib sau ua ke: Cov yas zoo heev thiab lubricity saum npoo ua rau nws zoo tagnrho rau cov txheej txheem sib sib zog nqus xws li kos duab sib sib zog nqus thiab ultra- kos duab sib sib zog nqus (xws li tsheb roj tso tsheb hlau luam, plhaub).
Kub-rolled coil:
Vim tias qhov loj dua thickness kam rau ua thiab qhov kev hloov pauv loj dua, lub kaum sab xis thiab qhov ntev tswj tau yooj yim dua thaum tsim (tshwj xeeb yog dabtsi yog khoov), thiab qhov kev twv ua ntej rov qab tsis zoo.
Nto oxide nplai yuav flake tawm thaum lub sij hawm tsim, kis kab mob thiab ua kom ceev hnav.
Feem ntau yog siv rau kev tsim cov khoom siv nrog me me deformation thiab tsis tshua muaj qhov yuav tsum tau ua rau qhov tseeb angular.
4.Nws zoo li cas rau kev ua haujlwm tom ntej?
Txias-rolled coils: Zoo tagnrho blanks rau precision machining. Lawv tuaj yeem raug txiav ncaj ncaj, CNC machined, laser txiav, thiab lwm yam., kom tau txais qhov siab - precision qhov chaw. Lawv zoo heev nto tiav kuj yog tsim rau precision vuam (xws li laser vuam thiab kuj vuam), ua aesthetically pleasing welds.
Kub-rolled coils: Feem ntau yog siv los ua ib nrab- cov khoom tiav lossis cov khoom ntxhib- cov khoom siv tshuab. Lawv yog siv rau hnyav- lub luag haujlwm machining lossis rau cov khoom siv loj uas yuav tsis tau txais kev txiav txim siab ntxiv tom qab vuam. Ua ntej precision machining, nws yog feem ntau yuav tsum tau tshem tawm oxide txheej txheej thiab kho cov ntawv zoo.
5.Dab tsi yog cov lus qhia xaiv cov khoom siv?
Thaum siab precision, siab -zoo li, thiab complex forming yuav tsum tau, txias -rolled coils yuav tsum tau xaiv.
Cov ntawv thov: tsheb lub cev vaj huam sib luag, siab- cov khoom siv kawg (cov tub yees, tshuab ntxhua khaub ncaws), lub computer chassis, precision sheet hlau qhov chaw, tinplate (cov kaus poom dej haus), thiab xim-coated steel phaj substrates.
Thaum lub zog, toughness, thiab tus nqi yog qhov tseem ceeb rau kev txiav txim siab, thiab qhov yuav tsum tau muaj qhov loj thiab qhov chaw tsis siab, kub - dov coils tuaj yeem siv.
Daim ntawv thov: tsim steel qauv, tsheb chassis, ntim, engineering machinery thav duab, thiab conveying pipelines. Thaum siv los ua raw khoom rau txias- dov coils lossis welded kav, lawv kuj muaj nyob rau hauv daim ntawv ntawm kub - dov coils.
