Ikhoyili Yensimbi Eqoqwe Ngobandayo ye-SPCC

Isithombe Esifakiwe Sekhoyili Yensimbi Eqoqwe Ngobandayo ye-SPCC

Incazelo emfushane:

Igama: Ikhoyili Yensimbi Egoqiwe Ebandayo

Insimbi yekhabhoni egoqwe ngokubandayo (SPCC, SPCD, SPCE), insimbi yekhabhoni ephansi kanye nensimbi yekhabhoni ephansi kakhulu (DC01/St12, DC03/St13, DC04/St14), insimbi yokunyathela yezimoto (DC01-Q1, DC03-Q1, DC04 -Q1), imicu yensimbi yesakhiwo yekhabhoni egoqwe ngokubandayo (Q235, St37-2G, S215G), imicu yensimbi egoqwe ngokubandayo enamandla aphansi (JG300LA, JG340LA), njll.

Ububanzi bokujiya: 0.1mm-0.45mm

ububanzi obuhlukahlukene: 700mm-1000mm

Material: SPCC, SPCC, SPCD, SPCE, DC01, St12, DC03, St13, DC04, St14, Q235, St37-2G, S215G, JG300LA, JG340LA

Izici: Ngenxa yokuthi ayifakwanga, ubulukhuni bayo buphezulu kakhulu (i-HRB inkulu kuno-90), futhi ukusebenza komshini kubi kakhulu. Inqubo elula yokugoba engaphansi kwama-degrees angu-90 (eqondile kuya kokuqondisa okugobayo) ingenziwa. Ezinye izigayo zensimbi zingakhiqiza ukucubungula okuphindwe kane.

Imininingwane Yomkhiqizo

Amathegi Omkhiqizo

Ukubuka konke kwekhoyili egoqiwe ebandayo

Ikhoyili egoqiwe ebandayo yenziwe ngekhoyili egoqiwe eshisayo. Enqubweni egoqiwe ebandayo, ikhoyili egoqiwe eshisayo igoqiwe ngaphansi kwezinga lokushisa lokuphinda kusetshenziswe, kanti insimbi egoqiwe ngokuvamile igoqiwe ekushiseni kwegumbi. Ishidi lensimbi elinokuqukethwe okuphezulu kwe-silicon linobuthakathaka obuphansi kanye ne-plasticity ephansi, futhi lidinga ukushiswa ku-200 °C ngaphambi kokugoqiwa ebandayo. Njengoba ikhoyili egoqiwe ebandayo ingashiswa ngesikhathi senqubo yokukhiqiza, azikho iziphambeko ezifana ne-pitting kanye ne-iron oxide ezivame ukutholakala ekugoqiweni okushisayo, futhi ikhwalithi yobuso kanye nokuphela kuhle.

Inqubo Yokukhiqiza Ikhoyili Egoqekile Ebandayo

Ikhoyili egoqekile ebandayo yenziwe ngekhoyili egoqekile eshisayo, futhi inqubo yayo yokukhiqiza ivame ukudlula ezinqubweni eziyinhloko njengokulungiswa kwezinto zokusetshenziswa, ukugoqa okubandayo, ukwelashwa kokushisa, ukulinganisa kanye nokuqeda.

Ukusebenza komkhiqizo we-Cold Rolled Coil

I-roll kanye nethebhulethi cishe kuyiphakheji elisikiwe. I-coil ebandayo itholakala ngokufaka i-pickling kanye nokufaka i-hot rolled coil ebandayo. Kungashiwo ukuthi uhlobo lwe-coil ebandayo egoqiwe. I-coil ebandayo egoqiwe (isimo esihlanganisiwe): I-coil eshisayo egoqiwe itholakala ngokufaka i-pickling, ukugoqisa okubandayo, ukunamathisela i-hood, ukuleveling, (ukuqeda).

Kunezinhlobo ezintathu eziyinhloko zomehluko phakathi kwazo:

Ngokubukeka, i-coil evamile ebandayo ayisheleli.

Amashidi asongiwe abandayo njengekhwalithi yobuso, isakhiwo kanye nokunemba kobukhulu kungcono kunezikhoyili ezibandayo.

Ngokuphathelene nokusebenza, ikhoyili ebandayo etholwe ngqo ngemva kwenqubo yokugoqa ebandayo yekhoyili egoqiwe eshisayo iyaqiniswa ngesikhathi sokugoqa ebandayo, okuholela ekwandeni kwamandla okukhiqiza kanye nengxenye yokucindezeleka kwangaphakathi okusele, kanti ukubukeka kwangaphandle "kunzima" kakhulu. Ibizwa ngokuthi ikhoyili ebandayo.

Ngakho-ke, amandla okukhiqiza: ikhoyili ebandayo inkulu kunekhoyili egoqekile ebandayo (isimo esigoqekile), ukuze ikhoyili egoqekile ebandayo (isimo esigoqekile) ibe ngcono kakhulu ekunyathelweni. Ngokuvamile, isimo sokulethwa esizenzakalelayo samakhoyili agoqekile abandayo siyagoqekile.

Ukusetshenziswa kweshidi lensimbi eligoqiwe elibandayo

Ikhoyili egoqekile ebandayo inokusebenza okuhle, okungukuthi, ngokugoqeka okubandayo, umugqa ogoqekile obandayo kanye neshidi lensimbi elinobukhulu obuncane kanye nokunemba okuphezulu kungatholakala, ngokuqondeka okuphezulu, ukushelela okuphezulu kobuso, ubuso obuhlanzekile nobukhanyayo beshidi eligoqekile elibandayo, kanye nokumbozwa okulula. Ukucubungula okufakwe ipulasitiki, ukuhlukahluka, ukusetshenziswa okubanzi, kanye nezici zokusebenza okuphezulu kokunyathela kanye nokungagugi, iphuzu eliphansi lesivuno, ngakho ishidi eligoqekile elibandayo linokusetshenziswa okubanzi, okusetshenziselwa kakhulu ezimotweni, izigubhu zensimbi eziphrintiwe, ukwakhiwa, izinto zokwakha, amabhayisikili, njll. Imboni nayo iyisinqumo esingcono kakhulu sokukhiqizwa kwamashidi ensimbi agqokiwe angokwemvelo.

Ububanzi bohlelo lokusebenza:
(1) Ukucutshungulwa kube ukugoqa okujwayelekile okubandayo ngemva kokumboza; ukumboza;
(2) Iyunithi yokugaya nge-galvanizing enedivayisi yokwelapha ngaphambi kokufakelwa i-annealing iyacutshungulwa ukuze i-galvanizing;
(3) Amaphaneli angadingi nhlobo ukucutshungulwa.
