Koiri Hurihia Wera
He rauemi taketake te koiri hurihuri wera i roto i te umanga maitai. Ka hangaia mā te tukanga hurihuri pāmahana teitei, ā, he iti te utu, he kaha teitei, he pai hoki te mahi tukatuka. He whānuitia te whakamahinga i roto i te hanga, te mīhini, ngā motuka, te hanga kaipuke me ētahi atu mara.
Whakamāramatanga taketake
Ko te koiri hurihuri wera (HRC) e pā ana ki ngā hua maitai e hurihia tonutia ana ki runga ake i te pāmahana hangarua (te nuinga o te wā >900°C) e ngā pereki iti (pērā i ngā pereti, i ngā pereki iti rānei) ā, i te mutunga ka piko.
Rerekētanga mai i te koiri hurihuri matao: Ehara te koiri hurihuri wera i te koiri hurihuri matao, he taratara te mata, he iti te tika o ngā āhuatanga, engari he teitei te kaha, ā, he pai te ngāwari, he mea e tika ana mō te hanga wāhanga hanganga.
Ngā āhuatanga matua
| Ngā Āhuatanga | Koiri hurihuri wera | Koiri hurihuri matao |
| Te tukanga whakaputa | Te hurihuri i te pāmahana teitei (>900°C) | Te hurihuri pāmahana noa (tukatuka matao) |
| Kounga mata | Tauine waikura, taratara | He maeneene, he tino tika |
| Kaha | Iti (engari he pakari pai) | Teitei (whakapakeketanga mahi) |
| Utu | Iti | Teitei |
| Ngā tono | Ngā wāhanga hanganga, ngā paipa, ngā anga waka | Ngā wāhanga tino tika, ngā taputapu kāinga, ngā panera motuka |
3. Tukanga whakaputa
Te whakamahana: Ka whakamahanahia te maitai ki te 1100~1250°C hei whakangawari.
Te hurihuri taratara: Te hanga tuatahi mā roto i tētahi mira hurihuri pēhanga teitei.
Te whakaoti i te hurihuri: Whakahaerehia te matotoru ki te rahi e hiahiatia ana (pēnei i te 1.2 ~ 20mm).
Te takai: I muri i te hurihuri, ka hurihia hei takai rino (ko te whānui o waho he 1 ~ 2 mita te nuinga).
Whakamatao: Whakamatao ā-taiao, whakamatao whakahaeretia rānei (pērā i te tukanga TMCP).
Ngā whakaritenga noa
Matotoru: 1.2~25mm (noa 2.0~6.0mm).
Whānui: 600~2200mm (1250mm, 1500mm noa).
Rauemi: Q235B (te maitai waro ma), SS400 (te paerewa Hapanihi), A36 (te paerewa Amerika), S355JR (te paerewa Ūropi).
Ngā āhuatanga hangarau: te kaha kume 300~500MPa, te kaha whakaputa 200~400MPa.
Ngā wāhi tono matua
Ahumahi hanga: H-kurupae, hanganga maitai, piriti, pae maitai.
Te hanga mīhini: ngā mīhini hangarau, ngā taputapu keri, te oko pēhanga.
Ahumahi motuka: anga, pū wira, hanganga anga.
Ahumahi paipa: paipa whakarewa, paipa porowhita (pērā i te maitai paipa API 5L).
Ahumahi hanga kaipuke: pereti kaipuke, hanganga pakitara.
He mea nui ki te kamupene te kounga o ngā hua, he nui te haumi ki te whakaurunga o ngā taputapu matatau me ngā tohunga ngaio, ā, ka whakapau kaha ki te whakatutuki i ngā hiahia o ngā kiritaki i te kāinga me tāwāhi.
Ka taea te wehewehe i te ihirangi ki: te hanganga matū, te kaha tuku, te kaha kume, te āhuatanga pānga, me ētahi atu
I taua wā anō, ka taea hoki e te kamupene te whakahaere i te kimi hapa me te whakamahana me ētahi atu tukanga maimoatanga wera i runga ipurangi e ai ki ngā hiahia o te kiritaki.
