Yuav ua li cas txias - rolled chev siv hauv kev tsim kho kev tsim kho? Dab tsi yog nws cov txiaj ntsig dhau kub-}} rolled coil?
Cov ntawv thov tseem ceeb hauv kev tsim kho yog:
Lub teeb ntuag steel hlau nplaum: rau nyias - preced steel, siab}} rolled coil nrog ib tuab ntawm 0.5-1.2mm;
Xim -} coated steel vuas / rau kev ua kom zoo nkauj, xaiv cov xim txias tshaj lossis sib npaug rau 20μm);
Qhov rooj thiab qhov rai thav ntawv: rau qhov sib npaug ntawm lub zog thiab ductility, xaiv}}} txheej kub ntau dua lossis sib npaug rau 80g / m²).
Cov txiaj ntsig zoo: Cov tuab tuab qhov tseeb (ua kom nruj nteg tig), yuav tsum muaj cov txheej txheem polrvanizing (galvanizing / xim txheej txuas lub neej).
Dab tsi yog qhov tshwj xeeb xav tau rau txias -}} rolled chev hauv kev lag luam hluav taws xob? Cov ntaub ntawv dab tsi nquag siv? Kev lag luam hluav taws xob (xws li mobile xov tooj ntawm tes thiab lub computer chassis) muaj cov kev txwv tshwj xeeb:
Tsis tshua muaj qhov tseeb ntawm qhov tseeb (thickness reariation ± 0.01mm) kom ntseeg tau tias feem sib xyaw ua ke;
Tsis tshua muaj qhov chaw nyob qis (ra tsawg dua los yog sib npaug rau 0.4μm) kom tau raws li qhov xav tau;
Ib puag ncig cov phooj ywg (rohs thiab mus txog kev ua raws, cov hlau hnyav - dawb).
Cov ntaub ntawv ua: DC05 (hluav taws xob kos duab kos duab)} {} {} plated cowers-rolled txias-rolled cold (rau kev txhim kho conductivity thiab hnav tsis kam).
Dab tsi cov ntsiab lus tseem ceeb yuav tsum tau txiav txim siab thaum xaiv txias - rolled chev? Cov txheej txheem xaiv yuav tsum ua kom haum rau daim ntawv thov cov xwm txheej, nrog cov kev txiav txim siab tseem ceeb:
Cov Cuab Yeej Siv Cov Neeg Kho Tshuab: Xaiv cov txiaj ntsig lub zog thiab elongation raws txoj kev ua (piv txwv, dc04 nrog ib tug elongation ntau dua lossis sib npaug rau 35% rau cov stample).
Qhov xwm txheej saum npoo: Xaiv cov kev kho mob saum npoo av (}
Qhov loj me: Xaiv cov tuab (0.1-3 hli) thiab dav (1200mm yog ib hom) raws li cov khoom sib txawv.
Tus nqi: Rau qhov kev ua tau zoo sib npaug, tso pa txias- Rolled chev yog tsawg dua xim gal6- coated coil. Kev sib npaug ntawm kev ua tau zoo thiab tus nqi yog qhov tseem ceeb heev.
Mob khaub thuas - rolled coil yuav siv rau welded Cheebtsam? Yuav ua li cas ceevfaj yuav tsum tau noj thaum lub sij hawm vuam?
Nws tuaj yeem siv rau kev siv cov khoom siv vuam (xws li cov qauv tsheb thiab cov qauv hlau), tab sis cov kev txiav txim siab hauv qab no siv:
Material Selection: Low-carbon steel (such as DC01 and Q235) has good weldability, while medium- to high-carbon steel (such as 65#) requires preheating to prevent cracking.
Kev kho deg: thaum vuam galvanized txias-}} txheej ua rau muaj cov yeeb ncuab lom, xav tau kev tiv thaiv. Isti {-} xeb pleev xim yuav tsum tau siv tom qab vuam los tiv thaiv xeb ntawm Weld.
Cov txheej txheem vuam: Siv Argon arc vuam lossis co2 roj tiv thaiv vuam los tiv thaiv oxidation. Lub vuam tam sim no yuav tsum tsis txhob ua kom dhau los tiv thaiv kev hlawv los ntawm nyias-}}}} rolled chev.
Yuav ua li cas yuav tsum txias- rolled coil yuav khaws cia kom tsis txhob xeb thiab puas tsuaj? Cia Yuav Tsum Mus Kom Ua Raws Li Yoisture {{}} pov thawj, siab}} {{}}} Cov ntaub ntawv yuav tsum:
Ib puag ncig: Muab cia rau hauv ib qho chaw qhuav, cua daj cua dub (txheeb ze cov av noo qis dua lossis sib npaug rau 60%). Zam txhob qhib - huab cua cia (nag thiab lwg muaj peev xwm ua rau xeb).
Stacking: Siv cov kev txhawb nqa (lossis cov ntoo ntoo). Cov coils hlau yuav tsum tau khaws cia sawv cev (kom tsis txhob muaj kev cuam tshuam los ntawm kev pw tiaj). Stacking qhov siab yuav tsum tsis txhob tshaj peb txheej (kom tiv thaiv deformation ntawm cov hauv qab coil).
Kev tiv thaiv: dog dig cold - rolled coils yuav tsum tsis txhob muab cia rau ntau tshaj peb lub hlis (raws li lawv tau nquag ua rau oxidation). Galvanized / Xim {- coated txias {3} Yuav tsum tau tshuaj tiv thaiv cov hmoov yas (los tiv thaiv cov hmoov yas), thiab cov tshuaj tiv thaiv kab mob kom tsis txhob raug kuaj xyuas tsis tu ncua.
