Iyini ishubhu yesikwele enamandla aphezulu?

Izici zokusebenza zeishubhu yesikwele enamandla aphezuluzinamandla aphezulu, ukuqina okuhle kanye nokumelana nokushayisana.
Amandla: iphuzu lokukhiqiza (σ s) ≥390mpa；
Amandla okudonsa (b b) ≥635mpa；
ukunwebeka δ 5 (%) ≥25 ；
Ubulukhuni hb ≤ 187hv,
Imininingwane yokwelashwa kokushisa: ukwenza kube ngokwejwayelekile okungu-850 ° C; Ukucima okungu-880 ° C; Ukushisa okungu-600 ° C.
Izinto zokwakha: zenziwe ngekhwalithi ephezuluinsimbi yesakhiwo sekhabhoningokugingqa okushisayo noma ngokudweba okubandayo.
Ukusetshenziswa: okusetshenziselwa ukukhiqiza ipayipi lodonga elipholile ngamanzi, ipayipi lamanzi abilayo, ipayipi lomusi lethangi lamanzi le-locomotive kanye nepayipi lezitini ze-arch, njll.
Ukucaciswa kanye nekhwalithi yokubukeka:
Iqoqo ngalinye leamapayipi ensimbikufanele ihlolwe ngayinye ngayinye, futhi ubuso kufanele bungabi nemifantu, imigoqo kanye neziphambeko zesikhumba ezimbili; Ukutholwa kwamaphutha e-Ultrasonic kufanele kwenziwe epayipini ngalinye lensimbi ukuhlola izakhiwo zemishini ze-weld. Ngokuvamile, ububanzi bokuqinisa obude be-weld bungu-0.2-0.25mm, ububanzi bokuqinisa obude be-weld ejikelezayo bungu-0.75-1mm, kanti ukuqinisa ukucindezeleka okude kusokhethi akufanele kube ngaphansi kuka-0.25mm
Ukwakheka kwamakhemikhali Ukwakheka kwamakhemikhali komkhiqizo oqediwe kuhambisana nezinhlinzeko ze-GB 222-84.
Izakhiwo zomzimba nezemishini:
1) Ijika lokucindezeleka kokuhlolwa kokucindezelwa kufanele libe yisicaba ngaphandle kokushintsha okungazelelwe
2) Ukuhlolwa komthelela Ukuqina komthelela wesampula okushisa okuphansi kuhlolwa ngendlela yokuhlola yokugoba okubandayo ekushiseni okucacisiwe
3) Imifantu ayivunyelwe emapayipini avuthelwe amadivayisi e-hydraulic noma e-pneumatic
4) Ukungavumelani kokucindezeleka kokuhlolwa kokugoba akufanele kudlule inani elibekiwe.
Ukugeleza kwenqubo: Ngemva kokuba umucu wensimbi ufakwe ngokuzenzakalelayo ube yisimo sediski esincane futhi ukhiqizwa njalo, ulinganiswa nge-straightener ye-multi-pass, bese ungena kuyunithi yokushisela enemvamisa ephezulu. Iziphetho ezimbili zihlanganiswa nge-welder ye-lap enemvamisa ephezulu ukuze kwakheke i-welding eyindilinga ene-corrugated. Ngemva kokushisela, ipayipi lensimbi liyalinganiswa futhi linqunywe yiyunithi yokulinganisa nokusika. Ekugcineni, ipayipi lensimbi liyacinywa futhi liqiniswe yiyunithi yokuqeda, bese lifuthwa nge-primer ukuqedela inqubo yokukhiqiza.
