Ahakoa i raro i ngā āhuatanga pāmahana iti, ka mau tonu te P690te pakari o te pānga me te ngāwari, te ārai i te pakarukaru me te whakarite i te pono mō te wā roa.
5. Tukanga Hanga
Ko te hanga maitai kounga P690 e hiahiatia anate whakarewa matatau me te maimoatanga wera whakahaerekia tutuki ai tōna hanganga moroiti tino pai. Kei roto i te tukanga whānui:
-
Te Rewa Tuatahi– Te whakamahi i te oumu hiko āwhata (EAF) te oumu hāora taketake rānei (BOF).
-
Te whakapai ake– Te Ōumu Koro (LF) me te Whakakore Hauhanga Korehau (VD) hei tango i ngā poke.
-
Te Maka Tonu– Te hanga i ngā papa pereki, i ngā pereti rānei he ōrite te hanganga.
-
Te Hurihuri Wera– Ka hurihia ngā pereti ki te awhe matotoru e hiahiatia ana (te nuinga o te wā 6–120 mm).
-
Te tinei– Whakamatao tere kia tutuki ai te hanganga martensitic.
-
Te whakamahana– Te whakamahana anō kia whakahokia mai te ngāwari me te pakari.
-
Whakamātautau Ultrasonic me te Mata– Te whakarite kia kore he hapa o ngā pereti i mua i te tuku.
SAKYSTEELe whakamahi ana i ngā raina whakaputa hou hei whakamanate tika o ngā āhuatanga, te whakaotinga o te mata, me te ōritetanga ā-mīhiniputa noa i ia puranga P690.
6. Te Whakarewa me te Hanga
Ahakoa he kaha te maitai P690, kei te mau tonuka taea te whakarewa mā te whakamahi i ngā tukanga tuku ihopērā i te SMAW, SAW, GTAW, GMAW rānei — mēnā he tikate whakamahana i mua me te maimoatanga wera i muri i te whakarewa (PWHT)ka whāia ngā tikanga.
Ngā Tohutohu Matua mō te Whakarewa:
-
Whakamahanahia ki te 150–200°C hei whakaiti i te mōrearea o te pakaru hauwai
-
Kia mau tonu te pāmahana o te ara whakawhiti i raro i te 250°C
-
Whakamahia ngā irahiko iti-hauwai (hei tauira, E11018-G)
-
Whakahaerehia te PWHT i te 580–620°C hei whakamama i te ahotea
-
Kia āta whakamatao i muri i te whakarewanga hei ārai i te pikinga o te mārō
Mā te whakahaere tika i te wā whakarewa ka whakarite kia tika te mahingā hononga pakari, he iti rawa te mōrearea o te pakarukaru, te ngaronga rānei o te pakari.
7. Ngā Whakamahinga Noa
