1. Rauemi brazing
(1) Ko te nuinga o nga wa e whakamahia ana e te parahi te konutea te whakaki i te whakarewa me te hiriwa.Ko nga momo whakarewa parani parahi zinc brazing whakakī whakakī he b-cu62znnimusir, b-cu60zusnr me b-cu58znfer.Ko te kaha tensile o te hononga rino parani ka tae ki te 120 ~ 150MPa.I runga i te turanga o te konupora konutea whakakikorua whakarewa, Mn, Ni, Sn, AI me etahi atu huānga ka taapirihia kia rite ai te kaha o te hononga brazed ki te whakarewa turanga.
He iti te pāmahana rewa o te whakarewa parahi paraihini whakakikorua parahi.Ka taea te karo i te hanganga kino i te wa e whakarewahia ana te rino.He pai te mahi o te hononga brazing, ina koa ko te whakarewa whakakii parai kei roto i a Ni, penei i te b-ag50cuzncdni me te b-ag40cuznsnni, e whakarei ake ana i te kaha here i waenga i te whakarewa whakakī whakakī me te rino whakarewa.He mea tino pai mo te whakamahana o te rino maka nodular, ka taea e te hononga kia rite te kaha ki te whakarewa turanga.
(2) Ina whakamahia te parahi me te konutea mo te rino whakarewa, ka whakamahia te nuinga o te fb301 me te fb302, ara, te borax, te ranunga o te borax me te waikawa boric.I tua atu, he pai ake te rere o te h3bo340%, li2co316%, na2co324%, naf7.4% me nac112.6%.
I te wa e whakamahanahia ana te rino me te whakarewa parahi parahi whakakī, ka taea te kowhiri i nga rerenga penei i te fb101 me te fb102, ara ko te ranunga o te borax, te waikawa boric, te pāhare pāporo pūkōwhai me te pāhare pāporo fluoroborate.
2. Hangarau parani
I mua i te parai i te rino maka, te kauwhata, te waikura, te onepu, te poke hinu me etahi atu mea i runga i te mata whakarewa me ata tango.Ka taea te whakamahi i te horoi whakarewa pararopi hei tango i nga taaka hinu, ka taea te whakamahi tikanga miihini penei i te pupuhi kirikiri, te pupuhi pupuhi ranei, me nga tikanga hiko hei tango i te kauwhata me te waikura.I tua atu, ka taea te tango i te graphite ma te tahuna ki te mura o te waikura.
Ka taea te whakawera i te rino parani ma te mura, te oumu, te whakauru ranei.I te mea he ngawari te hanga o te SiO2 ki runga i te mata o te rino maka, kaore i te pai te awe o te wera i roto i te hau whakamarumaru.I te nuinga o te waa, ka whakamahia te rewharewha parani mo te parani.I te wa e whakakikoruatia ana nga mea mahi nui ki te konupora konupora whakakikorua whakarewa, me maputia he papa o te rewharewha parai ki runga i te mata kua horoia i te tuatahi, katahi ka tukuna nga mea mahi ki roto i te oumu mo te whakamahana, te whakamahana ranei ki te rama raima.Ina whakawerahia te mea mahi ki te 800 ℃, tāpirihia te rewharewha taapiri, whakamahana ki te wera wera, katahi ka waruhia nga mea ngira ki te taha o te hononga kia rewa ai te konuhono me te whakakii i te aputa.Hei whakapai ake i te kaha o te hononga parani, ka mahia te maimoatanga annealing i te 700 ~ 750 ℃ mo te 20min i muri i te parai, katahi ka mahia te whakamahana puhoi.
I muri i te parai, ka taea te tango i te rere me te toenga ma te horoi ki te wai mahana.Mena he uaua ki te tango, ka taea te horoi ki te 10% wairewa waikawa waikawa pungatara ranei, 5% ~ 10% wairewa wai waikawa phosphoric, katahi ka horoia ki te wai ma.
