China thekiso e tobileng batang rolled tšepe kela DC01-DC06 phahameng matla meqolo tšepe
tlhaloso
Cold rolled coil e bua ka khoele ea tšepe e phuthoang ka botenya bo itseng ka ho toba ke rolara ka mocheso oa kamore 'me e phuthetsoe ka khoele kaofela ke kholara.Ha ho bapisoa le coil e chesang, e batang e phuthoa bokaholimo bo khanyang, pheletso e phahameng, empa e tla hlahisa khatello e matla ea ka hare, ka mor'a hore serame se phutholohe hangata se hloka kalafo ea annealing.
Mokelikeli oa tšepe o chesang o sebelisoa e le lisebelisoa tse tala, ka mor'a ho khethoa ha asiti ho tlosa sekala sa oxide, ho pota-pota ho batang, ho pitika ka har'a coil e thata.Matla, boima, boima le index ea polasetiki ea li-roll tse thata li ntlafatsoa ke ho thatafala ha mosebetsi o batang ho bakoang ke ho fetoha ha serame ho tsoelang pele., kahoo ts'ebetso ea setempe e tla fokola, e ka sebelisoa feela bakeng sa deformation e bonolo ea likarolo.Likhoele tse tšetsoeng ka thata li ka sebelisoa e le lisebelisoa tse tala limela tse futhumatsang tsa dip-dip galvanizing hobane likhoele tse futhumatsang metsi li na le lithapo tsa deignition.Boima ba li-rolls tse thata ka kakaretso ke lithane tse 20-40.Li-pickling rolls tse chesang li lula li phuthoa ka mocheso oa kamore.Bophara ba ka hare ke 610mm.
Likarolo tsa sehlahisoa
Ka lebaka la ho se be le kalafo ea annealing, boima bo phahameng (HRB> 90), machinability e fosahetseng, e ka etsoa feela ka tlase ho likhato tse 90 tsa ho kobeha ka tsela e bonolo ea tataiso (ho ea ka lehlakoreng la khoele).
Ho e beha ka mokhoa o bonolo, ho roala ho batang ho sebetsoa le ho phuthoa motheong oa coil e chesang.Ka kakaretso, ke mokhoa o chesang oa ho roala - pickling - batang.
Cold phuthoa lakane e sebetswa ho tloha chesang phuthoa lakane mocheso kamoreng.Le hoja mocheso oa poleiti ea tšepe o tla phahama nakong ea ts'ebetso, o ntse o bitsoa ho roala ho batang.Ka lebaka la deformation e tsoelang pele e batang ea ho bilika ho chesang, thepa ea mochini e fokola 'me boima bo phahame haholo.E tlameha ho khantšoa ho tsosolosa lisebelisoa tsa eona tsa mochine, 'me tse se nang li-anneal li bitsoa li-coil tse thata.Hangata li-coil tse tšetsoeng ka thata li sebelisoa ho etsa lihlahisoa tse sa hlokeng ho kobeha kapa ho otlolloa.Li-coil tse nang le botenya bo ka tlase ho 1.0 li phuthoa ka mahlakoreng a mabeli kapa mahlakoreng a mane, ka mahlohonolo.
Kopo
Cold rolled strip e sebelisoa haholo ho etsa likoloi, lihlahisoa tsa motlakase, rolling stock, lifofane, lisebelisoa tse nepahetseng, lijo tse entsoeng ka makotikoting, joalo-joalo. Cold rolled plate ke khutsufatso ea poleiti e tloaelehileng ea k'habone e entsoeng ka tšepe e batang, eo hape e tsejoang e le poleiti e pholileng, e tsejoang hape e le poleiti e pholileng. joalo ka poleiti e pholileng e batang, ka linako tse ling e ngotsoe ka phoso e le poleiti e kolobisitsoeng e batang.Letlapa le batang ke lesela le chesang la tšepe ea sebopeho sa k'habone, le batang hape le kentsoeng lipoleiting tsa tšepe tse botenya bo ka tlase ho 4mm.Ka lebaka la mocheso o tloaelehileng oa mocheso, ha ho na sekala sa oxide, kahoo boleng ba holim'a poleiti e batang bo nepahetse, bo nepahetse bo phahameng, bo kopantsoe le phekolo ea annealing, thepa ea eona ea mochine le ts'ebetso ea ts'ebetso e molemo ho feta poleiti ea tšepe e chesang, libakeng tse ngata, haholo-holo lefapha la tlhahiso ea lisebelisoa tsa lapeng, butle-butle le nkile sebaka sa tšepe e kolobisitsoeng e chesang
