Cold Rolled and Cold Hard Coil

Ka whiwhihia te Cold Hard coil ma te tiki me te maeke o te porowhita wera. Ko te ahua o te matao hurihia coil.

Cold rolled coil (annealed state): wera takai porowhita ma roto i te pikau, 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.Mai i te ahua, pereti Maama makariri he iti te tae Micro Black 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 e okeoke ana te 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 porotaka-makao (te ahua kua oti te whakamaarama): ka whiwhi 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 tuku: he nui ake te porowhita matao pakeke i te porowhita matao (te ahua annealed), kia pai ake ai te porowhita matao (te ahua annealed) mo te tarai.
