Caij nplooj ntoos hlav Steel Cold Rolled Steel Sawb
Steel strip is a strip-shaped steel product with a thickness of ≤10mm, produced by steel rolling enterprises using hot-rolled or cold-rolled steel plates as raw materials through rolling into narrow and long strips, supplied in coils (narrow strip: width ≤600mm; wide strip: width >600 mm). Raws li ib qho tseem ceeb raw khoom rau downstream manufacturing, nws nta qhov siab qhov tseeb, yooj yim ua thiab cov khoom txuag.
Core Classifications (los ntawm Txheej Txheem / Khoom / Daim Ntawv Thov)
Los ntawm Txheej Txheem Ntau Lawm (Primary Classification)
| Hom | Kub-Rolled Steel Sawb | Txias-Rolled Steel Sawb |
|---|---|---|
| Rolling condition | Rolled above recrystallization temperature (>450-600 degree) | Rolled ntawm chav tsev kub, feem ntau yuav tsum tau annealing |
| Thickness Ntau | 0.8-12.0mm (qhov loj: 2-6mm) | 0.05-3.6mm (qib precision txog 0.01mm) |
| Surface condition | Nrog oxide nplai, tsaus grey, qis tiav | Smooth thiab tiaj tus, tsis muaj oxide nplai |
| Dimensional raug | Tsawg heev, siab ntev | Tsis tshua muaj siab, me me kam rau ua |
| Core Properties | Zoo plasticity, yooj yim tsim, tsis muaj zog | Ua haujlwm- hardened, siab zog / hardness, me ntsis plasticity |
| Tej kev siv | Lub tsev tsim, txuas hniav, tsheb thav duab, engineering machinery | Lub tsheb vaj huam sib luag, cov khoom siv hauv tsev, cov khoom siv precision, cov dej ntws |
