Uhlolojikelele lwe-Cold Rolled Steel Coil
Ikhoyili egoqiwe ebandayo yenziwe ngekhoyili egoqiwe eshisayo. Enqubweni egoqiwe ebandayo, ikhoyili egoqiwe eshisayo igoqwa ngaphansi kwezinga lokushisa le-recrystallization, futhi insimbi egoqiwe ngokuvamile igoqwa ekamelweni lokushisa. Ishidi lensimbi elinokuqukethwe kwe-silicon ephezulu line-brittleness ephansi kanye nepulasitiki ephansi, futhi lidinga ukushisisa libe ngu-200 °C ngaphambi kokugoqeka okubandayo. Njengoba ikhoyili egoqiwe ebandayo ayishisi ngesikhathi sokukhiqiza, akukho ukukhubazeka okufana ne-pitting kanye ne-iron oxide evame ukutholakala ekugoqeni okushisayo, futhi izinga eliphezulu kanye nokuqedwa kuhle.

Cold rolled Coil Grade
1. Uhlobo lwesiShayina No. Q195, Q215, Q235, Q275——Q—ikhodi yephoyinti lokukhiqiza (umkhawulo) wensimbi evamile ye-carbon structural steel, okuyisimo sezinhlamvu zokuqala zefonethiki zesiShayina ze-"Qu"; 195, 215, 235, 255, 275 - ngokulandelana bamele inani lephuzu labo lesivuno (umkhawulo), iyunithi: MPa MPa (N / mm2); ngenxa yezakhiwo ezibanzi zemishini yamandla ensimbi ye-Q235, ipulasitiki, ukuqina kanye nokushisela ensimbi evamile ye-carbon structural Kakhulu, ingahlangabezana kangcono nezidingo ezijwayelekile zokusetshenziswa, ngakho-ke ububanzi bokusebenza bubanzi kakhulu.
2. I-SPCC brand yaseJapane - Insimbi, i-P-Plate, i-C-cold, i-C yesine evamile.
3. I-Germany grade ST12 - ST-steel (Steel), ishidi lensimbi elibandayo eli-12-class.
Ukusetshenziswa Kwekhoyili Yensimbi Ebandayo
Ikhoyili egoqiwe ebandayo isebenza kahle, okungukuthi, ngokugoqeka okubandayo, umugqa ogoqekayo kanye neshidi lensimbi elinogqinsi oluncanyana nokunemba okuphezulu kungatholakala, ngokuqonda okuphezulu, ubushelelezi obuphezulu, indawo ehlanzekile nekhanyayo yeshidi eligoqiwe. , futhi kulula ukunamathela. Ukucubungula okugcwele, ukuhlukahluka, ukusetshenziswa okubanzi, kanye nezici zokusebenza kokunyathela okuphezulu nokungagugi, iphuzu eliphansi lesivuno, ngakho ishidi eligoqiwe elibandayo linokusetshenziswa okubanzi, ikakhulukazi elisetshenziswa ezimotweni, izigubhu zensimbi eziphrintiwe, ukwakhiwa, izinto zokwakha, amabhayisikili, njll. Le mboni futhi iyisinqumo esingcono kakhulu sokukhiqizwa kwamashidi ensimbi ahlanganiswe nge-organic.
