Cold Rolled ndi Cold Hard Coil

Cold Rolled ndi Cold Hard Coil

Cold Hard koyilo imapezedwa ndi pickling ndi kuzizira ndikugudubuza koyilo yotentha.Ndi mtundu wa koyilo wozizira.

Cold rolling coil (annealed state): nsonga yotentha yopiringizika kudzera mu pickling, kugudubuza kozizira, kutsekereza hood, kusanja, (kumaliza), kumatha kutenga koyilo Yozizira.

Kusiyana pakati pa Cold Rolled ndi Cold Hard:

1.Kuchokera pamawonekedwe, mbale yoziziritsa yotentha ndi yaying'ono yaying'ono yamtundu wakuda

2.The pamwamba khalidwe, Kapangidwe ndi kukula kulondola kwa Cold adagulung'undisa bwino kuposa Cold Hard.

3. Pakuchita:

Popeza Cold Hard coil yomwe imapezedwa mwachindunji ndi kuzizira kozizira, kuzizira kumagwira ntchito molimba panthawi yozizira, mphamvu zokolola zimawonjezeka ndipo kupsinjika kwina kwamkati kumakhalabe, ndipo maonekedwe akunja ndi ovuta, choncho amatchedwa Cold Hard coil..

Koyilo yoziziritsa kuzizira (malo opindika): koyilo yozizira kwambiri imapezedwa pomangirira hood musanagubuduze.Pambuyo pa annealing, kuuma kwa ntchito ndi kupsinjika kwamkati kumachotsedwa (kuchepetsedwa kwambiri), ndiko kuti, mphamvu zokolola zimachepetsedwa mpaka kuzizira.Asanagubuduze.

Choncho, zokolola mphamvu: ozizira kwambiri koyilo ndi wamkulu kuposa ozizira adagulung'undisa koyilo (annealed boma), kotero kuti ozizira adagulung'undisa koyilo (annealed boma) ndi yabwino kwa sitampu.
