Kowiri tira Hiko CB-A102

Ko te hiko kowiri tira te whakamahi panui

1. chromium kowiri tira he etahi parenga waikura (waikawa oxidizing, waikawa waro, cavitation), ātete wera me te kakahu ātete.I te nuinga o te waa ka whakamahia ki nga tipu hiko, matū, hinu me etahi atu taputapu taputapu.Chromium kowiri tira weldability rawakore, kia whakarongo ki te tukanga fehokotaki'anga, tikanga maimoatanga wera me te kōwhiringa o te hiko tika.

2. CR-13 kowiri tira he pakeke ake i muri i fehokotaki'anga me he ngāwari ki te whakaputa kapiti.Ki te whakamahia te taua momo o te chromium kowiri tira hiko (G202, G207) mo te fehokotaki'anga, me preheated reira i runga ake i te 300 ° C ka mataohia e pā ana ki 700 ° C i muri fehokotaki'anga.Ki te kore e taea te kawe te fehokotaki'anga maimoatanga wera pou-weld, na te whiriwhiri o te chromium-nickel kowiri tira hiko (A107, A207) .

3. Chromium 17 he kowiri tira, kia pai ake ai te aukati me te weldability me te whakanui ake i te nui o nga huānga pumau penei i Ti, Nb, Mo, me etahi atu, he pai ake te weldability i te chromium 13 kowiri tira.A, no te whakamahia te taua momo o te chromium kowiri tira hiko (G302, G307), kia preheated te reira i runga ake 200 ° C ka riria a tawhio noa 800 ° C i muri fehokotaki'anga.Ki te kore e taea te wera-tukinotia te fehokotaki'anga, na te whiriwhiri o te chromium-nickel kowiri tira hiko (A107, A207) .Ko te hiko kowiri tira CR-NI he pai te aukati i te waikura me te aukati waikura, e whakamahia nuitia ana i roto i te ahumahi matū, te tongi, te hinu, te hanga miihini hauora.

4. Ka taea te whakamahi i te 0 me raro iho mo te whakapiringa-katoa.

5. 0 me runga ake mo te whakapiri papatahi me te whakapiri awhi.

6. Chromium-nickel paninga kowiri tira he momo titanium-konupora me te momo hauwai iti.Ka taea te whakamahi momo konupūmā titanate i roto i te AC me te DC, engari te kătahi o te fehokotaki'anga AC pāpaku, i te ngāwari ki te whero, kia rite ki te whakamahi DC supply mana.Diamita

7. Me whakamaroke te electrode, me whakamaroke te momo titanium-calcium i te 150 ° C mo te 1 haora, me te momo hauwai iti me whakamaroke i te 200 ° C ki te 250 ° C mo te 1 haora (kaore he whakamaroke tonu, ki te kore. te paninga he ngawari ki te pakaru me te tihorea) , aukati i te paninga hiko e piri ana ki te hinu me etahi atu paru, kia kore ai e nui ake te ihirangi waro o te weld me te pa ki te kounga o te whakapiri.

8. Kia kore ai te waikura i waenganui i nga kanohi ka puta mai i te whakamahana, kaua e nui rawa te waa o te whakapiri, kia iti iho i te waro hiko hiko mo te 20%, kaua te ARC e roa rawa, kia tere te whakamahana i waenga i nga paparanga, ki te kuiti pirepire he tika. .
