Kupanga chitsulo chosapanga dzimbiri kalasi 317L kumafuna kuthamanga pang'ono komanso chakudya chokhazikika kuti muchepetse chizolowezi chake chogwira ntchito molimbika.Chitsulo ichi ndi cholimba kuposa chitsulo chosapanga dzimbiri 304 chokhala ndi zingwe zazitali;Komabe, kugwiritsa ntchito chip breakers ndikulimbikitsidwa.Kuwotcherera kungathe kuchitidwa pogwiritsa ntchito njira zambiri zosakanikirana ndi kukana.Kuwotcherera kwa Oxyacetylene kuyenera kupewedwa.AWS E/ER 317L zitsulo zodzaza ndi zofunika.
Njira zochiritsira zotentha zitha kuchitidwa.Zinthuzo ziyenera kutenthedwa mpaka 1149-1260 ° C (2100-2300 ° F);komabe, sayenera kutenthedwa pansi pa 927 ° C (1700 ° F).Kuti muchepetse kuwonongeka kwa dzimbiri, annealing pambuyo pa ntchito ndikulimbikitsidwa.
Kumeta, kupondaponda, mutu ndi kujambula n'zotheka ndi kalasi ya 317L zitsulo zosapanga dzimbiri, ndipo annealing pambuyo pa ntchito annealing akulimbikitsidwa kuthetsa kupsyinjika mkati.Annealing imachitidwa pa 1010-1121 ° C (1850-2050 ° F), yomwe iyenera kutsatiridwa ndi kuzizira kofulumira.
Kalasi 317L chitsulo chosapanga dzimbiri sichimayankha kutentha.
Mapulogalamu
Gulu 317L chitsulo chosapanga dzimbiri chimagwiritsidwa ntchito kwambiri pazotsatira izi:
- Condensers mu zinthu zakale
- Kupanga zamkati ndi mapepala
- Malo opangira magetsi a nyukiliya
- Zida zamagetsi ndi petrochemical process.
