Vim tias cov phaj txias zoo tib yam carbon structural steel tsis tau muab tshem tawm, nws qhov hardness yog siab heev (HRB yog ntau dua 90), thiab nws cov machinability tsis zoo, yog li nws tsuas tuaj yeem ua tau yooj yim kev taw qhia bending tsawg dua 90 degrees (perpendicular mus rau coiling kev taw qhia). ).
Txhawm rau muab nws yooj yim, txias dov yog ua tiav thiab dov los ntawm lub hauv paus ntawm kub dov coils. Feem ntau hais lus, nws yog txheej txheem kub dov-pickling-txias dov.
Cold-dov yog ua los ntawm cov ntawv kub-dov los ntawm chav tsev kub. Nws yuav tsum tau annealed los kho nws cov khoom siv kho tshuab, thiab cov uas tsis muaj annealing yog hu ua nyuaj dov coils. Hard-rolled coils feem ntau yog siv los ua cov khoom uas tsis tas yuav khoov lossis ncab, thiab cov tuab ntawm tsawg dua 1.0 yog dov rau ob sab lossis plaub sab nrog hmoov zoo.

Cold-rolled strips yog dav siv, xws li tsheb tsim, khoom siv hluav taws xob, dov Tshuag, aviation, precision instruments, kaus poom zaub mov, thiab lwm yam. Cold-rolled sheet yog cov ntawv luv ntawm cov qauv carbon zoo tib yam steel txias dov ntawv, los yog txias. -rolled sheet, feem ntau hu ua cov ntawv txias dov, thiab qee zaus sau yuam kev ua ntawv txias-dov. nws cov khoom siv kho tshuab thiab cov txheej txheem ua tau zoo dua li cov ntawv kub dov steel, hauv ntau qhov chaw, tshwj xeeb tshaj yog nyob rau hauv kev tsim khoom siv hauv tsev, nws tau maj mam hloov cov ntawv kub dov.
