Yuav ua li cas cov qoob loo lis loj ntawm txias - rolled chev cuam tshuam nws txoj kev ua tau zoo? Nws tau sim li cas?
Grain loj yog hais txog qhov loj ntawm cov nplej hauv cov hlau (qhia raws li "qib qib," nrog cov qhab nia siab dua qhia me me cov nplej).
Cuam tshuam:
Cov nplej me me ua kom cov hlau lub zog thiab hardness (thaum tseem txhim kho nws cov plhuav dav thiab kev nruj (zam brittle backstrat).
Ntau dhau cov nplej loj nplej ua rau cov khoom sib txawv thiab muaj feem ntau rau cov kev tawg hauv zos thaum lub sijhawm stamping.
Txoj Kev Kuaj Xyuas: Pom nyob rau hauv meTallographic tsom iav: → Soj ntsuam cov qhab nia ntawm cov qib (piv txwv rau cov kab ke
Dab tsi yog lub hom phiaj ntawm "khoov kuaj" rau txias - rolled coil? Nws tau ua li cas?
Bend xeem ntawv yog siv los ntsuas cov hlau cov plasticity thiab cov ua haujlwm txias (seb nws yog qhov cuam tshuam rau khoov thiab tawg). Txheej Txheem Ua Haujlwm:
Kuaj: txiav ib 100 hli x 20mm hnoos qeev (tuab sib npaug rau cov thawj tuab ntawm cov hlau phaj, t);
Dabtsi yog khoov: muab cov quav rau ntawm lub tshuab dabtsi yog 180℃ntawm kev siv hluav taws xob uas tau hais tseg (piv txwv li ntawm 3 hli, kev khoov radius r}}}}}}}});
Kev ntsuam xyuas: saib cov hnoos qeev tom qab dabtsi yog khoov. Yog tias tsis muaj kab nrib pleb lossis kev ua kom pom tseeb, piv txwv li cov khoom siv tau rau Q235 txias {poll yuav tsum tau ua kom tau tawg).
Dab tsi yog cov kev ua tau zoo sib txawv ntawm txias -}} rolled coils ua los ntawm cov khoom sib txawv? Kev noj cov ntaub ntawv ua piv txwv, kev ua kom sib txawv yog raws li hauv qab no:
Cov Khoom Siv Tawm Tawm Zog (Mpa) Tensile Lub Zog (Mpa) Elongation (%) Cov Nta Tseem Ceeb
DC {01 140-280 270-410 Ntau dua los yog sib npaug rau 28 General qib, tsim nyog rau cov khoom siv stamping yooj yim
DC {04 120-240 260-380 Ntau dua lossis sib npaug ntawm 38 sib sib zog nqus daim duab, zoo plasticity, haum rau cov stamping nyuaj
Q 345 345-460 470-630 Ntau dua los yog sib npaug rau 21 qis alloy, siab zog, haum rau cov txheej txheem kev teeb tsa
65 # {{{440-600 690-830 Ntau dua los yog sib npaug 12 Cov Hlau Carbon Steel, siab hardness, haum rau Springs

Dab tsi cov khoom siv tau txias - rolled coils feem ntau siv rau hauv kev lag luam automotive? Hom tau xaiv li cas?
Kev lag luam automotive yog thaj chaw ua haujlwm tseem ceeb rau txias - rolled chev, suav rau kwv yees li 30%. Cov txheej txheem tseem ceeb thiab xaiv cov qauv suav nrog:
Lub cev panels (qhov rooj, hoods): Yuav tsum muaj lub ntsej muag du thiab zoo nkauj; Xaiv DC06 (Ultra -}} Lub cev nqus nqus kos duab) lossis yog tias hlau;
Cov txheej txheem txheej txheem (thav ntawv thav ntawv, kab ke): Xav tau lub zog siab; Xaiv Q345 lossis HC340la (Automotive Cov Hlau Tsim Qauv);
Cov Khoom Siv Sab Hauv (Ntsuas Cov Vaj Huam Sib Luag nkhaus): Xav tau nruab nrab muaj zog thiab kev muaj zog; Xaiv DC03 lossis SPCC;
Lub caij nplooj ntoo hlav (lub rooj zaum lub rooj zaum): Yuav tsum muaj kev nyuaj siab; Xaiv 65 # lossis 70 # txias - rolled coil (xav tau tom qab quenching).
Cov khoom lag luam twg hauv cov khoom lag luam hauv tsev siv kev lag luam txias- rolled chev? Dab tsi yog qhov yuav tsum tau ua rau txias-} rolled coil? Cov khoom siv hauv tsev kev lag luam muaj kwv yees li 25% ntawm cov ntawv thov. Cov khoom tseem ceeb thiab cov kev xav tau:
Cov kab ke (tog tub yees, tshuab ntxhua khaub ncaws oter nruas): xav tau ib tug du, corrosion {{0} {resistant nto. Xaiv cov galvanized txias- rolled coil (Electrogalvanized, sib npaug ntawm 0.8μm) lossis xim} coated txias- rolled chev.
Sab hauv Liner (Tub Yees Tawm Tub Yees, Yuav Tsum Tau Zoo Evaporator): Yuav tsum muaj cov ntshiab huv thiab tsis muaj ntxhiab. Xaiv DC03 (Khoom noj qib qib, RoHS ua raws li).
Bracket (cua txias sab nraum zoov chav tsev BRACKET): Xav tau lub zog siab. Xaiv Q235 lossis Spcc (yuav tsum muaj xeb tom qab- ua pov thawj).
