1. Dab tsi yog txias dov coil

Cold rolled coil, tseem hu ua CRC, yog ib hom khoom siv hlau uas yog tsim los ntawm kub dov ca steel thiab yog tus cwj pwm los ntawm cov thicknesses me me thiab kev siv tshwj xeeb.

Cold-rolled steel yog hais txog cov hlau tsis tshua muaj carbon uas tsim los ntawm txoj kev "txias dov" thiab ua tiav ntawm qhov chaw nyob ze ntawm chav tsev kub. Cold-dov steel muaj superior zog thiab machinability. Cov nplooj ntawv txias-dov steel feem ntau yog siv rau cov khoom tsim khoom uas yuav tsum tau ua kom nruj, sib sib zog nqus, ncaj thiab coated nto.

Cold-rolled steel yog tsim nyob rau hauv txias txo mills qhov twg cov khoom yog txias nyob ze ntawm chav tsev kub, ua raws li los ntawm annealing thiab / los yog tempers dov. Cov txheej txheem no tsim cov hlau uas muaj ntau yam ntawm qhov chaw tiav thiab zoo dua hauv kev ua siab ntev, concentricity, thiab ncaj nraim piv rau cov hlau kub-dov. Cold-dov hlau muaj cov ntsiab lus ntawm cov pa roj carbon tsawg, thiab cov txheej txheem annealing ua rau lawv softer dua li cov ntawv kub dov. Cov khoom siv txias-dov steel feem ntau yog ua los ntawm cov ntawv, strips, tuav thiab rods.

2.Cold-dov coil classification, cov khoom ntau thiab cov khoom

Cov qauv siv nyob rau hauv ntau lub teb chaws los teeb tsa cov kev cai rau cov hlau txias, xws li EN 10130, EN 10268, EN 10209, ASTM A1008 / A1008M, DSTU 2834, GOST 16523, GOST 9045, GOST 17066 thiab lwm yam. qhov luaj li cas rau txias-dov coils, lawv daim ntawv thov (profiling, txias forming, enamelling, dav siv, thiab lwm yam), mechanical zog, nto zoo thiab lwm yam tsis.

3.Cold-dov coils raws li European qauv

Feem ntau ua raws li European cov qauv rau kev tsim cov tshuab txias txias yog EN 10130, EN 10268 thiab EN 10209.

EN 10130 yog siv rau cov khaub thuas dov coils ua los ntawm cov pa roj carbon tsawg DC01, DC03, DC04, DC05, DC06 thiab DC07 steel qib rau txias sib sau tsis muaj txheej, nrog qhov dav yam tsawg kawg nkaus ntawm 600 hli thiab qhov tsawg kawg nkaus thickness ntawm 0.35 hli.

4.Cov yam ntxwv ntawm Cold Rolled Coil

Cov yam ntxwv tseem ceeb ntawm cov khaub thuas dov coils suav nrog qhov tseeb qhov ntev, txhim kho cov khoom siv kho tshuab, thiab zoo dua saum npoo zoo dua li cov ntawv kub dov.

Txias dov kuj ua rau nws muaj peev xwm los tsim cov ntawv nyias nyias uas tsis tuaj yeem tsim hauv cov kub dov mills. Cov kev lag luam tseem ceeb uas siv cov tshuab txias txias yog siv lub tshuab tsim, cov khoom siv, kev tsim kho, tsheb. Thaum nws los txog rau kev tsim kho kev lag luam, txias-kuav los tiag coils yog siv los tsim façade ntsiab, steel qauv, khoov kaw thiab qhib profiles, thiab lwm yam.
