Nikara chromium vs rino chromium konumohe: He aratohu whiriwhiri oumu ahumahi

2026-04-10

I roto i te oumu ahumahi te kōwhiringa, te rauemi o koranu whakamahana hiko he mea nui e whakatau tika ana i te pai o te mahi a te taputapu, te roa o te ratonga, me ngā utu whakahaere mō te wā roa. Mō oumu ahumahi ngā kaiwhakahaere me ngā kaimahi hoko, mā te whiriwhiri i te koranu whakamahana hiko tika e kore e taea anake te whakarite i te whakaputanga pumau engari ka whakaitihia hoki ngā whakapaunga tiaki me te whakakapinga. Koranu nikara-konukōmiuma (NiCr), pērā i te Cr20Ni80 māka, me te koranu rino-konupora-konumohe (FeCrAl), tae atu ki HRE, SGHT, me SGHYZ, ko ngā kōwhiringa e rua e tino rongonui ana i te mākete. Ko Beijing Shougang Gitane, he tohunga koranu whakamahana hiko kei konei te kaiwhakarato hei āwhina i a koe ki te wehewehe mārama i ngā rerekētanga i waenga i ēnei momo koranu e rua, kia taea ai e koe te whiriwhiri tika e tino ōrite ana ki tāu oumu ahumahingā tikanga mahi motuhake me ngā hiahia whakaputa.

Koranu nikara-konukōmiuma (NiCr) e mōhiotia whānuitia ana mō ōna painga matua, tae atu ki te ngāwari o te hanga, te ngāwari o te hanga, me te ātete pai ki ngā ru wera. Ka mau tonu te mahi pumau mai i te pāmahana rūma ki te 1100℃, he mea tino pai mō ngā oumu ahumahi e hiahia ana ki ngā huringa tīmatanga-mutu maha, ā, he uaua hoki ngā hanganga, pērā i ngā oumu taiwhanga, ngā oumu maimoatanga wera iti, me ngā taputapu whakamahana tino tika. Nā Shougang Gitane koranu nikara-konukōmiuma he mea hanga ngā hua mai i ngā rauemi mata parakore teitei, ā, ko ngā Waea whakamahana hiko Cr20Ni80 ā, he tino pai te tū a te rīpene me te ātete pumau me te kaha whakarewa. Nā ēnei āhuatanga he mea pai mō ngā tono whakahaere pāmahana tika pāmahana waenga me te iti, he mea nui te pumau me te pono ki te whakarite i te kounga hua.

He rerekē, koranu rino-konupora-konumohe (FeCrAl) he nui ake ngā painga e tukuna ana e ia i roto i ngā taiao pāmahana teitei, tae atu ki te ātete pai ki te pāmahana teitei, te roa o te mahi, me te whai hua nui. Ka taea e tōna pāmahana mahi teitei te eke ki te 1420℃, he teitei ake i te konukōre nikara-konukōmiuma, e pai ai mō ngā āhuatanga mahi pāmahana teitei. Ko ngā hua FeCrAl mahi teitei a Shougang Gitane, tae atu ki te SGHT (i hangaia mā te tukanga whakarewa paura ODS), SGHYZ, me HRE, ka hangaia he paparanga konumohe waikura matotoru ki runga i te mata i te wā e whakamahia ana, ka whakarei ake i tō rātou ātete ki te waikura me te ātete ki te ngoki. Nō reira, ko te roa o tō rātou oranga mahi he 3 ki te 5 ngā wā i tērā o ngā koranu nikara-konupora noa, ā, he whakataetae ake te utu. He tino pai ēnei hua mō ngā oumu ahumahi pāmahana teitei e mahi ana i waenga i te 1000℃ me te 1400℃, pērā i ngā oumu whakawera, ngā oumu rewa, me ngā oumu maimoatanga wera tonu, e whakamahia whānuitia ana i roto i ngā momo mara ahumahi.

Hei āwhina i a koe ki te whiriwhiri i te mea tino tika, anei ētahi tohutohu whiriwhiri mārama: mēnā kei te pāmahana ≤1000℃ te oumu ahumahi e mahi ana, ā, me maha ngā huringa tīmatanga-mutu, ko te koranu nikara-konukōmiuma te kōwhiringa tino pai; mēnā kei te pāmahana ≥1000℃ te oumu e mahi ana, ā, me roa te wā e mahi tonu ana, Shougang GitaneE tino taunakihia ana ngā hua koranu FeCrAl a Shougang Gitane (SGHT/SGHYZ/HRE). Hei kaiwhakarato koranu whakamahana hiko ngaio me te wheako nui, ka whakaratohia e Shougang Gitane te whānuitanga katoa o ngā hua nikara-konupora me te konupora rino-konupora-konumohe, mai i ngā taumata paerewa ki ngā rauemi whakarewa paura ODS kounga teitei. Ka tukuna hoki e mātou ngā hua waea me ngā hua rīpene kua whakaritea kia rite ki ō hiahia motuhake, hei āwhina i ō oumu ahumahi kia mahi pai me te pumau, ā, hei whakaiti i ō utu whakaputa mō te wā roa.
