Cov ntawv txias txias
Nrov specifications yog nyob rau hauv luv luv khoom!
nyem kom tau daim ntawv qhia tshwj xeeb!
Cov ntawv txias dov yog ua los ntawm cov khoom zoo kub dov coil. Tom qab xaiv thiab tshem tawm cov nplais hlau oxide, cov khoom dov tau raug rov qab txias dov deformation, annealing, sib sau, xov thiab lwm yam txheej txheem. Nws muaj cov yam ntxwv ntawm corrosion kuj thiab haum rau kev tsim kho, kev lag luam thiab lwm yam kev lag luam.
Cov txheej txheem txias txias steel coil (phaj) yog raws li hauv qab no:
- Kev npaj cov khoom siv raw: txias dov steel coil ntau lawm tsuas yog siv cov kub dov los yog kub dov steel phaj raws li cov khoom siv raw cov ntaub ntawv no ua ntej yuav tsum tau ua cov kev kuaj xyuas kom paub tseeb tias nws ua tau raws li qhov yuav tsum tau ua.
- Ua ntej-kev kho mob: Cov khoom siv raw yog rhuab thiab ntxuav kom tshem tawm cov oxides thiab cov av, ua rau saum npoo ntawm daim tawv nqaij smoother thiab npaj rau kev ua haujlwm tom ntej.
- Txias dov: cov khoom siv raw yog pub rau hauv ntau-dhau txias dov mills rau dov Cov mills no feem ntau muaj 4-6 kis, txhua tus nrog ib txoj kab uas hla ntawm yob, thiab cov khoom siv raw yog dov mus rau qhov xav tau tuab thiab dav los ntawm nias thiab ncab Nyob rau hauv tus txheej txheem ntawm txias dov, nto kev kho mob xws li trimming, polishing thiab polishing.
- Pickling: Tom qab dov, steel phaj yog pickled kom tshem tawm cov oxide ntawm daim tawv nqaij thiab xeb nplai ntawm qhov chaw thiab txhim kho lub tiaj tus thiab ua tiav ntawm cov hlau phaj nto.
- Oiling: Tom qab pickling, steel phaj yog oiled los tiv thaiv nto oxidation thiab corrosion, thiab txo kev sib txhuam thiab khawb thaum stacking, thauj thiab ua.
- Txiav: Lub phaj steel yog txiav rau hauv qhov xav tau ntev thiab dav kom tau raws li qhov xav tau ntawm kev lag luam sib txawv.
- Ntim: Cov ntawv txiav steel yog ntim thiab sau nrog cov ntaub ntawv tseem ceeb, xws li phaj specifications, batch tooj thiab hnub tsim khoom.
