Cov khoom ua los ntawm cov hlau uas yog tsim los ntawm kev txo qis txias muaj xws liStainless hlau Cold Rolled Coils. Qhov no suav nrog kev dhau qhov kub txav ntawm cov yob ntawm chav tsev kub kom txo qis thiab ua haujlwm ntawm qhov zoo. Txias dov muab cov lus txib tseeb tshaj qhov tuab thiab dav, thaum txhim kho lub zog thiab ua tiav qhov chaw. ASTM International, European Norms, Japanese Industrial Standards, Suav National Standards, ISO Standards, thiab DIN Standards tag nrho siv rau txias-dov stainless hlau coils. Cov qauv no qhia txog cov qauv hluavtaws, cov khoom siv kho tshuab, kev tiv thaiv, thiab kev ua tiav saum npoo. Qhov zoo thiab kev ua tau zoo ntawm stainless hlau txias dov coils uas xav tau yog lav los ntawm kev nkag siab cov qauv no.
Dab tsi yog Cov Txheej Txheem Txias Rolling ntawm Stainless Hlau?
Lub caij txias dov ntawmstainless hlausuav nrog qee qhov kev txav mus los hloov cov khoom tsis zoo rau hauv cov khoom zoo tagnrho. Ntawm no yog ib qho kev tawg ntawm qhov txias dov ntawm Stainless Steel Cold Rolled Coils:
Thawj kauj ruam yog los sib sau ua ke cov khoom ntuj tsim rau tempered steel tsim, uas tsis tu ncua suav nrog hlau hlau, chromium, npib tsib xee, thiab lwm yam alloying Cheebtsam.
Txhawm rau tsim molten stainless hlau, cov ntaub ntawv raw yog yaj nyob rau hauv ib qho hluav taws xob arc lossis induction rauv.
Cov kua tempered steel yog projected rau hauv seem los yog billets, uas yog ces txias thiab hardened.
Cov chunks los yog billets yog warmed mus rau high kub thiab mus los ntawm ib tug zuj zus ntawm rollers kom txo lawv cov thickness thiab ua rau lawv mus rau hauv curls los yog nplooj ntawv. Lub voj voog no yog lub npe hu ua kub dov thiab tsim kub-tsav hardened hlau.
Nyob rau hauv cov txheej txheem hu ua pickling, nto impurities ntawm kub dov stainless hlau zoo li nplai thiab oxides raug tshem tawm nrog acid. Qhov no npaj cov hlau rau cov theem hauv qab no.
Lub pickled stainless hlau yog ces raug rau txias dov, nyob rau hauv uas nws yog txo nyob rau hauv thickness los ntawm ib tug series ntawm rollers ntawm chav tsev kub. Qhov kev sib cuam tshuam no tsim cov hardness thiab lub zog ntawm tempered steel thaum ua haujlwm ntawm nws qhov ua tiav thiab txheej txheej.
Tom qab txias dov, lub hardened steel mus los ntawm toughening, ib tug siv txoj kev kho. Nws suav nrog kev ua kom sov cov hlau mus rau qhov kub thiab txias tom qab nws maj mam los txhim kho nws qhov yooj yim, durability, thiab kev cuam tshuam yaig.
Lub tempered kho steel yog feem ntau raug rau daim tawv nqaij dhau mus ua hauj lwm rau nws nto tiav thiab tshem tawm tej blemishes.
Qhov kawg txav mus rau tus kab mob txav mus los tau ua tiav, qhov twg cov hlau tawv tawv raug txiav, tsim, thiab npog los ntawm cov ntsiab lus zoo. Slitting, shearing, polishing, thiab txheej nrog cov yeeb yaj kiab los yog cov khoom siv yog txhua txoj hauv kev ua kom tiav qhov no.
Cov txheej txheem txias dov ntawm stainless hlau yog qhov tseem ceeb rau kev ua tiav cov khoom siv zoo tagnrho, ua tiav saum npoo, thiab txheej txheej precision. Nws ua rau nws muaj peev xwm ua tau ntau yam khoom siv hlau stainless uas siv rau hauv kev tsim kho, tsheb, kev ua zaub mov, khoom siv hauv tsev, thiab kev tsim kho, thiab lwm yam.
Dab tsi Standard yog Cold Rolled Stainless Steel?
Stainless hlau Cold Rolled Coilsyog tsim los ntawm cov txheej txheem thoob ntiaj teb sib txawv los lav nws qhov zoo thiab tsim nyog rau ntau yam kev siv. Qee cov qauv siv dav tshaj plaws rau txias-dov stainless hlau yog raws li hauv qab no:
Cov kev cai rau chromium thiab chromium-nickel stainless hlau phaj, ntawv, thiab sawb siv rau hauv cov hlab ntsha siab thiab lwm yam kev siv dav dav tau teev tseg hauv cov qauv ASTM A240 / A240M. Cov qauv no suav nrog ntau yam kev kho steel qib, suav nrog austenitic, ferritic, thiab duplex hom.
Specifications rau stainless hlau yog muab los ntawm EN 10088 series ntawm cov qauv. Kev xa tawm cov xwm txheej rau corrosion-resistant stainless hlau ntawv / phaj thiab sawb yog nyob rau hauv EN 10088-2, thaum lub sij hawm kev xa khoom tej yam kev mob rau semi-tiav khoom, tuav, rods, thiab cov hom phiaj dav dav yog nyob rau hauv EN {{4} }. Ntxiv mus, EN 10151 qhia txog qhov yuav tsum tau ua ua ntej rau Cold-rolled stainless hlau sawb rau springs.
JIS G4305 yog tus qauv Nyij Pooj uas txiav txim siab cov cua txias txav tempered steel daim hlau, nplooj ntawv, thiab strips rau kev siv dav dav. Nws suav nrog austenitic, ferritic, thiab martensitic hom stainless hlau ntawm lwm tus.
Lub teb chaws Suav tus qauv rau txias-kuav los tiag stainless hlau nplooj ntawv, daim hlau, thiab strips yog GB / T 3280. Cov qib austenitic, ferritic, thiab martensitic stainless hlau yog tag nrho cov txheej txheem no. Lwm cov ntsiab lus GB / T, zoo li GB / T 4237, muab cov khoom tsim nyog rau cov ntawv kub-dov stainless hlau thiab cov ntawv.
TS EN ISO 9445 Cov txheej txheem thoob ntiaj teb uas qhia txog qhov muaj peev xwm ntawm cov qauv thiab cov qauv rau kev hloov mus tas li txias kho steel nyias strip. Nws npog qhov dav txog li 600 hli thiab thicknesses txog 6 hli.
Cov no tsuas yog ob peb piv txwv ntawm cov lus qhia feem ntau siv rau Stainless Steel Cold Rolled Coils. Raws li lub koog tsev kawm ntawv, kev lag luam, thiab cov kev xav tau tshwj xeeb, cov ntsiab lus sib txawv xws li Racket (Deutsches Institut für Normung) thiab NFA (Fabkis cov lus qhia pej xeem) kuj yuav tsim nyog.
Thaum xaiv cov hlau tsis muaj txias txias, nws yog ib qho tseem ceeb uas yuav tsum sab laj cov qauv tsim nyog thiab cov lus qhia tshwj xeeb kom ntseeg tau tias cov khoom ua tau raws li qhov yuav tsum tau muaj, cov khoom siv kho tshuab, nto tiav, thiab qhov ntev ntev. Kev ntseeg siab, sib xws, thiab kev siv tau zoo tuaj yeem ua tiav los ntawm kev ua raws li cov lus qhia no.
Hauv kev xaus,txias dov steel coilsyog ib yam khoom tseem ceeb hauv ntau lub lag luam. Lawv muaj zog, ruaj, thiab zoo nkauj txaus nyiam, ua rau lawv zoo tagnrho rau ntau hom kev siv.Yog tias koj xav kawm ntxiv txogStainless hlau Cold Rolled CoilsTube, txais tos hu rau peb:jasonxie@metaldyj.com.
