Te Huri Matao me te Coil Maamaa Matao

Te Huri Matao me te Coil Maamaa Matao

Ka whiwhihia te Cold Hard coil ma te pikau me te whakamatao i te porowhita wera wera.Ko te ahua o te matao hurihia coil.

Cold rolled coil (annealed state): wera takai porowhita i roto i pickling, cold rolling, hood annealing, leveling, (oti), ka taea te tiki Cold rolled coil.

Te rereketanga i waenga i te Cold Rolled me te Cold Hard :

1.From te ahua, matao pereti Hard he iti Micro Black tae te tikanga

2.Ko te kounga o te mata, Ko te hanganga me te rahi o te tika o Cold Rolled he pai ake i te Cold Hard.

3. Mo te mahi:

I te mea ko te Cold Hard coil i whiwhi tika mai i te tukanga hurihuri makariri, i roto i te tukanga hurihuri makariri ka whakapakeketia te mahi i te wa o te hurihuri makariri, ka piki te kaha o te hua me te noho tonu etahi ahotea o roto, a he uaua te ahua o waho, no reira ka kiia ko Cold Hard coil..

Ko te porowhita-makao (te ahua kua oti te whakamaarama): ka whiwhihia te porowhita matao ma te whakahiato i mua i te hurihanga.Whai muri i te whakahiatotanga, ka whakakorehia te ahua whakapakeke o te mahi me te ahotea o roto (kua tino heke), ara, ka heke te kaha tuku ki te tata makariri.I mua i te hurihuri.

Na reira, ko te kaha o te tuku: he nui ake te porowhita matao pakeke i te porowhita makariri (te ahua annealed), kia pai ake ai te porowhita matao (te ahua annealed) mo te tarai.
