AWS E309L-16 Biraha aan daahin ee gacanta
Codsiga&Standard&Ogaysiis:
1. Ku haboon birta aan wasakhda lahayn iyo birta kaarboon ama birta alxanka yar ee alxanka birta ah ee aan la midka ahayn, alxanka birta isku dhafan ee alxanka, 308 taxane alxanka birta aan wasakh lahayn ee birta kaarboon ama birta alloy hoose.
2. Heerka aan la kulanay: GB/T983 E307-16, AWS A5.4 E307-16 & A5.4M E307-16, ISO3581-A:E(18 9 Mn Mo) R 1 2, ISO3581-B:ES307- 16
Codsiga: loo isticmaalo isla NOOC ka mid ah qaab-dhismeedka birta ahama, birta ka kooban iyo qaybaha birta ka duwan in fiber synthetic, petrochemical iyo qalabka kale ee wax soo saarka, sidoo kale waxaa loo isticmaali karaa reactor nuclear, dusha weelka cadaadis derbiga gudaha lakabka wareejinta iyo alxanka qaybta munaaradda gudaha.
Astaamaha
1. Kaalshiyam kaalshiyamka birta ah ee birta ah, ka kooban ugu weyn waa 22% CR-12% Ni;
2. Qandho deggan, qaab-dhismeed qurux badan, dooxyo yaryar, dillaacyo yar, si fudud u-dejinta, caabbinta dabka wanaagsan ee maqaarka daroogada, caabbinta caloosha oo wanaagsan.
3. Birta alxanka waxay ka kooban tahay ferrite badan waxayna leedahay dareen dildilaac hooseeya.
Kaalshiyamka calcium nooca ultra-hooseeya carbon Cr23Ni13 ahama electrode, waxaa loo isticmaali karaa labada AC iyo DC, iyada oo aan niobium, titanium iyo walxo kale oo kiimiko deggan sidoo kale iska caabin karaa daxalka intercrystalline uu keeno roobab carbide. Waxaa loo isticmaalaa birta aan la taaban karin, birta isku dhafan iyo birta aan la mid ahayn, sida fiber synthetic, petrochemical iyo qalab kale.
Diyaarinta alxanka ka hor:
Electrode wuxuu u baahan yahay inuu ahaado 300 ~ 350 ℃ 1 saac qalajinta, waqti qoyaan daran si ay u bixiso heerkulka sare ee qalajinta ilaa 350 ℃ ama kordhinta ku haboon ee wakhtiga qalajinta, iyo qalajinta lakabka dhejinta ilaa inta suurtogalka ah ee aan ka badnayn 3 lakab; Ku dadaal in lagu isticmaalo qalajinta ama ku rid baaldiga korantada wax aan ka badnayn 2 maalmood si aad u badbaadiso, iska ilaali qalajinta labaad ee aan loo baahnayn, si aad uga hortagto dahaadhka korantada.
