Me pēhea te whiriwhiri i te waea whakamahana ātete

• (1) Mō ngā kamupene hoko pēnei i te hunga e hokohoko ana i ngā taputapu mīhini, ngā mīhini hiri, ngā mīhini tākai, me ētahi atu, ka tūtohu mātou kia whakamahia te waea NiCr o te raupapa cr20Ni80 nā te mea kāore e teitei te pāmahana e hiahiatia ana. He painga anō hoki te whakamahi i te waea NiCr. Ehara i te mea he pai te whakarewa, engari he ngawari ake, kāore hoki e pakarukaru. He pai ake te whakamahi i te āhua rīpene nā te mea he nui ake te kawenga mata mō ia mita tapawha o te rīpene i te waea porowhita. Haunga tōna whānui whānui, he iti ake tōna pakaru i te waea porowhita.
• (2) Mō ngā kamupene hoko pēnei i te hunga e mahi ana i ngā oumu hiko, ngā oumu tunu, me ētahi atu, ka tūtohu mātou i te 0cr25al5 FeCrAl tino noa, nā te mea ko ngā whakaritenga pāmahana ka rerekē mai i te 100 ki te 900°C. Ahakoa me whakaaro ki ngā take o te pāmahana me te pikinga o te pāmahana, kāore e hiahiatia te whakamahi i te waea whakamahana ātete me te kounga me te mahi pai rawa atu. Ehara i te mea he iti noa te utu, engari ko te pāmahana mahi mōrahi ko te 900°C. Mena kua tukuna te mata o te waea whakamahana ātete ki te maimoatanga wera, ki te maimoatanga waikawa, ki te whakamahana rānei, ka paku whakarei ake ōna āhuatanga waikura, ka hua ake he ōwehenga utu-mahi teitei ake.
  • Mena kei te whakahaerehia te oumu i te 900 ki te 1000°C, ka tūtohu mātou kia whakamahia te 0cr21al6nb nā te mea he roa ake te manawanui o tēnei raupapa waea whakamahana ātete ki te pāmahana, ā, he tino pai rawa atu hoki tōna kounga nā te tāpiri o ngā huānga Nb.
  • Mena kei te whakahaerehia te oumu i te 1100 ki te 1200°C, ka tūtohu mātou kia whakamahia he waea porowhita o te Ocr27al7mo2 nā te mea kei roto he MO, ā, ka nui ake te manawanui ki te pāmahana. Ko te teitei ake o te parakore o te Ocr27al7mo2, ko te teitei ake o tōna kaha kume, ā, ko te pai ake o ōna āhuatanga waikura. Heoi anō, ka pakarukaru haere. Nō reira, me tino tupato te whakahaere i te wā e hiki ana, e whakatakoto ana. He pai ake te tuku i te wheketere ki te takai ki ngā rahi e tika ana kia taea ai e te kamupene hoko te whakamahi anō mō ​​tana tono ki tana wheketere.
  • Mō te oumu e mahi ana i te pāmahana teitei ake o te 1400°C, ka tino taunaki mātou i a TK1 mai i TANKII, i te sedesMBO o Amerika, i te Kanthal APM rānei o Huitene. Kāore e kore, ka nui ake te utu.
• (3) Mō ngā kamupene hoko pēnei i te hunga e hokohoko ana i ngā uku me ngā karāhe, ka tohutohu mātou kia whakamahia tika te HRE mai i TOPE INT'L, te waea whakamahana ātete kawemai rānei. Nā te mea ka wiri nui te waea whakamahana ātete i raro i ngā pāmahana teitei. Ki te pāngia e te wiri mō te wā roa, ka pirau te waea whakamahana ātete kounga iti, ā, ka pangia ngā hua whakamutunga. Mā te whiriwhiri i te waea whakamahana ātete kounga teitei anake, ka tutuki he ōwehenga utu-mahi pai ake.
