Kupanga ndi Kuchiza Kutentha
Kuthekera
Mukuyang'ana zida zowunikira zitsulo zanu?
Gulu 317 chitsulo chosapanga dzimbiri ndi cholimba kuposa 304 chitsulo chosapanga dzimbiri.Ndibwino kugwiritsa ntchito chip breakers.Kuuma kwa aloyiyi kudzachepetsedwa ngati zakudya zokhazikika komanso zothamanga zochepa zimagwiritsidwa ntchito.
Kuwotcherera
Gulu la 317 chitsulo chosapanga dzimbiri chitha kuwotcherera pogwiritsa ntchito njira zophatikizira ndi kukana.Njira yowotcherera ya Oxyacetylene simakonda pa aloyi iyi.AWS E/ER317 kapena 317L filler zitsulo zitha kugwiritsidwa ntchito kupeza zotsatira zabwino.
Hot Working
Gulu 317 zitsulo zosapanga dzimbiri zimatha kutenthedwa pogwiritsa ntchito njira zonse zomwe zimagwiritsidwa ntchito potentha.Imatenthedwa pa 1149-1260 ° C (2100-2300 ° F).Siziyenera kutenthedwa pansi pa 927 ° C (1700 ° F).Annealing pambuyo pa ntchito angathe kuchitidwa kuti asunge dzimbiri kukana dzimbiri.
Ntchito Yozizira
Kudinda, kumeta, kujambula, ndi mitu zitha kuchitidwa bwino.Annealing pambuyo pa ntchito ikuchitika pofuna kuchepetsa nkhawa mkati.
