Te takai makariri
① Ka whakamahia te "Taehia te kowiri tira / porowhita" hei rauemi mata, ka hurihia ki roto i te mira makariri i te pāmahana noa. Te matotoru tikanga <0.1mm ~ 3mm>, te whanui <100mm ~ 2000mm>;
② He pai te ahua o te mata maeneene me te maeneene, te tika o te taha teitei me nga taonga miihini pai. Ko te nuinga o nga hua ka hurihia, ka taea te tukatuka ki nga pereti maitai whakakikoruatia;
③ Te tukanga whakangao kowiri tira / kowiri tira makariri:
⒈ pīkara → ⒉ te pāmahana noa okeoke → ⒊ tukanga whakahinuhinu → ⒋ annealing → ⒌ flattening → ⒍ tapahi pai → ⒎ tākai → ⒏ tae ki te kaihoko.
Werohia wera
① Ka whakamahia te mira wera-wera ki te hanga i te tira tira me te 1.80mm-6.00mm te matotoru me te 50mm-1200mm te whanui.
② [Hot-rolled strip/sheet] He painga o te iti o te pakeke, te ngawari o te tukatuka me te pai o te ductility.
③ Te mahi whakangao o te takai wera kowiri tira / coil:
⒈ pickling → ⒉ teitei pāmahana okeoke → ⒊ tukanga whakahinuhinu → ⒋ annealing → ⒋ whakaene ⒍ ⒍ tapahi pai → ⒎ tākai → ⒏ tae te kiritaki.
He rereke te wera me te makariri
① He pai te kaha me te tauwehenga hua, he pai te kaha me te tauwehenga o te tira tira wera wera.
② He pai ake te kounga o te mata, te ahua me te tika o te ahu o te takai rino matao-hurihia i era o te rino wera.
③ He tino angiangi te matotoru o te takai takai makariri, he nui te matotoru o te tira wera.
