1: Te whakamahana Mo nga koranu Hastelloy B-2, he mea tino nui ki te pupuri i te mata kia ma, kia kore e poke i mua i te wa whakamahana.Ka pakarukaru a Hastelloy B-2 ki te whakamahana i roto i te taiao kei roto he whanariki, he ūkuikui, he mata, me etahi atu whakakino whakarewa iti, te nuinga mai i nga tohu tohu, te pāmahana e tohu ana i te peita, te hinu me te wai, te paowa.Ko te hau rewharewha me whai whanariki iti;hei tauira, ko te whanariki whanariki o te hau maori me te hau hinu hinu e kore e neke ake i te 0.1%, ko te whanariki o te hau taone e kore e neke ake i te 0.25g/m3, a ko te whanariki o te hinu hinu kare i neke atu i te 0.5%.Ko te whakaritenga o te taiao hau mo te oumu whakawera he taiao kore, he taiao whakaheke marama ranei, a kaore e taea te rereke i waenga i te oxidizing me te whakaheke.Kaore e taea e te mura o te oumu te pa tika ki te koranu Hastelloy B-2.I te wa ano, me whakamahana nga mea ki te pāmahana e hiahiatia ana i te tere whakawera tere, ara, me whakaara te pāmahana o te oumu whakawera ki te pāmahana e hiahiatia ana i te tuatahi, katahi ka whakauruhia nga mea ki roto i te oumu mo te whakamahana. .
2: Ko te mahi wera Hastelloy B-2 koranu ka taea te mahi wera i roto i te awhe o te 900 ~ 1160 ℃, me tineia ki te wai i muri i te tukatuka.I roto i te tikanga ki te whakarite i te parenga waikura pai, kia annealed reira i muri i te mahi wera.
3: Ko te mahi makariri Hastelloy B-2 koranu me whai maimoatanga otinga.I te mea he nui ake te pakeke o te mahi i te kowiri tira austenitic, me ata whakaaro nga taputapu hanga.Mena ka mahia he tukanga hanga matao, he mea tika te whakahiato i waenga.A, no te nui atu te deformation mahi matao 15%, e hiahiatia maimoatanga otinga i mua i te whakamahi.
4: Te maimoatanga wera Me whakahaere te pāmahana maimoatanga wera otinga i waenga i te 1060 ~ 1080 ° C, katahi ka whakamataohia te wai ka tineia, ka eke ranei te matotoru o te rauemi ki runga ake i te 1.5mm, ka tere te whakamahana o te hau kia whiwhi ai i te pai o te waikura.I nga wa katoa o te whakamahana, me mahi tupato ki te horoi i te mata o te papanga.Ko te maimoatanga wera o nga taonga a Hastelloy me nga waahanga taputapu me aro ki nga take e whai ake nei: Hei aukati i te maimoatanga wera o nga waahanga taputapu, me whakamahi nga mowhiti whakakaha kowiri tira;te pāmahana oumu, te whakamahana me te wa whakamahana me tino whakahaere;Me mahi i mua i te maimoatanga hei aukati i nga kapiti waiariki;i muri i te maimoatanga wera, ka whakamahia te 100% PT ki nga waahanga wera;Mena ka puta nga kapiti waiariki i te wa e rongoa ana i te wera, ko te hunga e hiahia ana ki te whakatika i te raima i muri i te huri me te whakakore me tango i tetahi tikanga whakatikatika motuhake.
5: Whakakorea Ko nga waikura i runga i te mata o te koranu Hastelloy B-2 me nga piro e tata ana ki te tui whiri me whakakoi ki te wira huri pai.I te mea he tairongo te koranu Hastelloy B-2 ki te reo whakahaora, ka nui ake te hau hauota-kei roto i te wa o te mahi pikara.
6: Ko te miihini Hastelloy B-2 koranu me mahi miihini i roto i te ahua o te reera, a me tino mohio ki tana mahi whakapakeke.Ko te paparanga whakapakeke me tango i te reeti whangai nui ake, me te pupuri i te taputapu ki te mahi tonu.
7: Welding Hastelloy B-2 koranu weld whakarewa me te rohe wera-wera he ngawari ki te whakaheke i te wahanga β me te arahi ki te Mo rawakore, he pai ki te waikura intergranular.Na reira, me ata hangai me te tino whakahaere i te tukanga whakapiri o Hastelloy B-2 koranu.Ko te tukanga fehokotaki'anga whānui ko e whai ake: te rauemi fehokotaki'anga ko ERNi-Mo7;te tikanga fehokotaki'anga ko GTAW;ko te mahana i waenga i nga paparanga mana kia kaua e neke ake i te 120°C;ko te diameter o te waea whakapiri he φ2.4 me te φ3.2;te naianei fehokotaki'anga ko 90 ~ 150A.I te wa ano, i mua i te whakapiri, me whakakorehia te waea waea, te riu o te waahanga me nga waahanga e tata ana ki te whakaheke me te whakaheke.He iti ake te kawe i te waiariki o Hastelloy B-2 i to te maitai.Mena ka whakamahia he riu V-ahua kotahi, me 70° te koki o te riu, me te whakauru wera iti.Ka taea e te maimoatanga wera i muri i te paihere te whakakore i te ahotea me te whakapai ake i te awangawanga pakaruhanga waikura.
