raw cov ntaub ntawv Cold rolling pickling coil feem ntau yog ua los ntawm longitudinal dov. Cov txheej txheem ntawm cov khoom siv txias dov feem ntau suav nrog cov khoom siv raw, pickling, dov, degreasing, annealing (kub kho), xov, thiab lwm yam. Cold rolling siv cov khoom kub dov ua raw khoom. Ua ntej txias-dov, cov khoom siv raw yuav tsum tau dephosphorized kom ntseeg tau tias cov khoom siv raw khoom Cold rolling pickling coil yog huv si.
