Cold dov thiab kub dov steel coils yog ob txoj kev tsim steel sib txawv uas txawv ntawm qhov ua haujlwm kub, khoom thiab siv. Cov hauv qab no yog qhov sib txawv tseem ceeb ntawm lawv:
1. Kev ua haujlwm kub:
Kub dov steel coils: Kub dov yog nqa tawm ntawm qhov kub thiab txias, feem ntau ntawm 1,100 degree thiab 1,300 degree. Qhov no yog qhov kub ntawm cov hlau tsim. Qhov kub siab no ua rau cov hlau yooj yim rau kev tsim, tab sis nws kuj ua rau cov tawv nqaij oxidized uas yuav tsum tau muab tshem tawm tom qab.
Cold dov coils: Txias dov yog nqa tawm ntawm chav tsev kub, feem ntau tsis tshaj qhov ntsuas kub. Qhov no muab cov khoom txias dov rau saum npoo zoo dua thiab tsis tas yuav tshem tawm cov tawv nqaij oxide.
2. Nto zoo:
Kub Rolled Chev: Vim yog kev tsim khoom ntawm qhov kub thiab txias, kub dov coils feem ntau muaj rougher nto thiab xav tau kev kho mob tom ntej kom tau txais qhov chaw tiaj tus thiab zoo.
Cold Rolled Coil: Cov txheej txheem txias dov muab lub ntsej muag zoo nkauj thiab zoo nkauj thiab feem ntau tsis tas yuav tsum tau kho qhov chaw ntxiv.
3. Mechanical Properties:
Kub Rolled Coils: Kub dov cov khoom feem ntau muaj qis zog thiab hardness, tab sis zoo dua plasticity rau daim ntaub ntawv uas yuav tsum tau molding thiab dabtsi yog khoov.
Cold rolled coils: Cov khoom siv txias txias feem ntau muaj zog dua thiab hardness, tab sis kuj qis dua plasticity, haum rau cov ntawv thov uas xav tau lub zog siab thiab precision.
4. Kev siv:
KUB ROLLED STEEL COILS: Kub dov hlau feem ntau yog siv rau kev tsim khoom ntawm cov khoom, phaj, profiles, thiab lwm yam, nrog rau cov ntawv thov uas xav tau molding.
Cold rolled steel coils: Cold rolled steel feem ntau yog siv rau hauv cov ntawv thov uas xav tau siab precision, flatness thiab nto zoo, xws li kev tsim tsheb, kev tsim khoom siv hluav taws xob, thiab cov khoom siv.
5. Nqi:
Kub dov coils: Cov txheej txheem ntau lawm ntawm kub dov hlau yog qhov yooj yim thiab feem ntau tsis tshua muaj nqi.
Cold rolled steel coils: txias dov manufacturing txheej txheem yog complex, feem ntau yog tus nqi siab dua.
Nyob rau hauv luv luv, txias dov thiab kub dov steel coils yog haum rau txawv daim ntaub ntawv thiab muaj ntau yam khoom thiab cov yam ntxwv. Qhov kev xaiv ntawm hom coil nyob ntawm seb qhov kev xav tau tshwj xeeb, nrog rau cov khoom siv, qhov zoo ntawm qhov chaw, tus nqi thiab kev ua haujlwm.
