Kev kos duab txias txias dov steel sc1 yog qhov tseem ceeb ntawm kub dov steel kauj uas dhau los ntawm kev ua haujlwm ntxiv. Cov hlau tau ua tiav ntxiv hauv cov tshuab txo qis, qhov twg cov khoom yog txias (ntawm chav tsev kub) ua raws li annealing thiab / lossis tempers dov. Cov txheej txheem no yuav tsim cov hlau nrog ze dua qhov ntev kam rau ua thiab ntau yam ntawm cov khoom tiav. Lub sij hawm Cold Rolled yog siv yuam kev rau txhua yam khoom thaum lub npe khoom yog hais txog kev dov ntawm cov ntawv tiaj tus dov thiab cov khoom coil.
Thaum xa mus rau cov khoom lag luam bar, lo lus siv yog "txias tiav", uas feem ntau muaj cov duab txias thiab / lossis tig, sib tsoo, thiab polishing. Cov txheej txheem no ua rau cov ntsiab lus siab dua thiab muaj plaub qhov zoo:
#1 Kev kos duab txias txias rolled steel sc1 ua rau kom muaj txiaj ntsig thiab muaj zog tensile, feem ntau tshem tawm cov kev kho cua sov ntxiv.
#2 Tig tau tshem ntawm qhov tsis zoo ntawm qhov chaw.
#3 Kev sib tsoo nqaim qhov qub me me kam rau ua ntau yam.
#4 Polishing txhim kho qhov chaw tiav.
Tag nrho cov khoom txias muab qhov zoo tshaj plaws saum npoo tiav thiab zoo dua hauv kev ua siab ntev, concentricity, thiab straightness thaum piv rau kub dov.
Cold drawing txias dov steel sc1 feem ntau nyuaj tshaj li kub dov steel coils vim muaj cov pa roj carbon ntau ntxiv. Txawm li cas los xij, qhov no tsis tuaj yeem hais txog cov ntawv txias dov thiab cov ntawv kub dov. Nrog rau ob yam khoom no, cov khoom txias-dov muaj cov pa roj carbon tsawg thiab feem ntau yog annealed, ua rau nws softer dua li cov ntawv kub dov.
Mechanical zog ntawm Cold drawing txias dov steel sc1
| Yield Rp 0.2 (MPa) | Tensile Rm (MPa) | Kev cuam tshuam KV (J) | Elongation A (%) | Kev txo qis hauv ntu ntu ntawm pob txha Z (%) | Raws li-kub-kho mob | HBW |
|---|---|---|---|---|---|---|
| 372 (Ntau dua lossis sib npaug) | 651 (Ntau dua lossis sib npaug) | 11 | 44 | 34 | Kev daws thiab Kev laus, Annealing, Ausaging, Q ntxiv T, thiab lwm yam | 312 |
