Kakaretso ea li-coil tse batang
Mohatsela o batang o entsoe ka khoele e kolobisitsoeng e chesang. Ts'ebetsong e batang, coil e chesang e phuthoa ka tlase ho mocheso oa recrystallization, 'me tšepe e phuthetsoeng ka kakaretso e phuthoa ka mocheso oa kamore. Letlapa la tšepe le nang le silicon e phahameng le na le brittleness e tlase le polasetiki e tlase, 'me e hloka ho futhumatsoa pele ho 200 ° C pele ho bata. Kaha coil e pholileng e batang ha e futhumale nakong ea tlhahiso, ha ho na liphoso tse kang pitting le iron oxide tse atisang ho fumanoa ka ho chesa ho chesang, 'me boleng ba holim'a metsi le ho qetela li ntle.
Mokhoa oa Tlhahiso ea Cold Rolled Coil
Coil e pholileng e batang e entsoe ka li-coil tse chesang tse chesang, 'me ts'ebetso ea eona ea tlhahiso hangata e feta lits'ebetsong tse kholo tse kang ho lokisetsa thepa e tala, ho roala ho batang, phekolo ea mocheso, ho lekana le ho qeta.
Ts'ebetso ea Cold Rolled Coil Product
Moqolo le letlapa li batla li le sephutheloana se sehiloeng. Coil e pholileng e fumanoa ka ho khetha le ho bata ho kolobisa coil e chesang. Ho ka boleloa hore ke mofuta oa khoele e batang. Cold rolled coil (boemo bo annealed): Khoeli e kolobisitsoeng e chesang e fumanoa ka ho khetha, ho roala ho batang, ho kenya hood, ho lekanya, (ho qeta).
Ho na le liphapang tse 3 tsa mantlha lipakeng tsa tsona:
Ka chebahalo, khoele e pholileng ka kakaretso e batla e le bohlasoa.
Lishiti tse phuthoang tse batang joalo ka boleng ba bokaholimo, sebopeho le ho nepahala ha litekanyo li molemo ho feta likhoele tse batang.
Mabapi le ts'ebetso, coil e pholileng e fumanoeng ka ho toba ka mor'a hore ho be le mokhoa o batang oa ho roala ha mocheso o chesang, o sebetsa ka thata nakong ea serame, e leng se etsang hore ho be le keketseho ea matla a lihlahisoa le karolo ea khatello ea ka hare e setseng, 'me ponahalo ea ka ntle e batla e le "thata." ". E bitsoa coil e pholileng.
Ka hona, matla a tlhahiso: khoele e pholileng e kholo ho feta khoele e pholileng (sebaka sa annealed), e le hore khoele e pholileng (sebaka sa annealed) e be e ntle haholo bakeng sa ho hatakela. Ka kakaretso, boemo ba kamehla ba ho fana ka li-coil tse kolobisitsoeng tse batang bo tlosoa.
