Cold Rolled Los xij
Nrov cov lus qhia tshwj xeeb yog qhov tsis txaus!
Nyem kom tau txais daim ntawv tshwj xeeb!
Cov ntawv txias txias yog ua los ntawm cov khoom kub zoo kub coil. Tom qab xaiv thiab tshem cov hlau oxide nplai, cov ntaub yob yog raug kom rov qab txias excormation, analing, sib sau, ua tiav thiab lwm cov txheej txheem. Nws muaj cov yam ntxwv ntawm corrosion tsis kam thiab yog haum rau kev tsim kho, ua lag luam thiab lwm thaj chaw.
Tus khaub thuas dov steel chev (phaj) cov txheej txheem ntau lawm yog raws li hauv qab no:
- Cov Khoom Siv Raw Ua: Txias Rolled Steel Chev Ntau Lawm Feem ntau yuav tsum muaj cov ntaub ntawv raw ua kom ntseeg tau tias nws ua tau ntau yam yuav tsum tau ua
- Pre6 - Kev Kho Mob: Cov khoom siv rhuab yog ntxuav kom tshem tawm cov npoo oxides thiab av, ua rau lub npoo hluav taws xob thiab npaj rau kev ua tiav tom ntej.
- Colding txias: cov khoom siv raw yog pub rau ntau cov roj colling thiab ncab}
- Pickling: Tom qab dov, lub phaj steel yog pickled kom tshem tawm cov tawv nqaij oxide thiab xeb nplai rau saum npoo thiab txhawm rau txhim kho lub tiaj tiaj thiab ua tiav ntawm cov hlau phaj.
- Roj Roj: Tom qab pickling, lub phaj steel yog oxidation los tiv thaiv kev sib txhuam thiab corrosion, thiab txo cov kev sib txhuam thiab kev thauj khoom thiab ua.
- Txiav: lub phaj steel yog txiav mus rau hauv qhov yuav tsum tau ntev thiab dav kom tau raws li cov kev xav tau ntawm kev lag luam sib txawv.
- NTIM: Kev txiav cov hlau txiav hlau tau ntim thiab sau npe nrog cov ntaub ntawv cuam tshuam, xws li phaj specifications, batch thiab hnub ua haujlwm ntau lawm.
