Ƙananan Zafin Karfe Walda Electrode
W607
GB/T E5015-G
AWS A5.5 E7015-G
Bayani: W607 wani lantarki ne na ƙarfe mai ƙarancin zafin jiki wanda ke da rufin sodium mai ƙarancin hydrogen. Yi amfani da DCEP (mai nuna wutar lantarki kai tsaye) kuma ana iya haɗa shi a kowane matsayi. Karfe da aka ajiye yana da ƙarfi sosai a -60°C.
Aikace-aikace: Ana amfani da shi don walda ƙarfe mai ƙarancin zafi kamar 09MnD.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.65 | ≤0.60 | 0.50 ~ 2.50 | ≤0.020 | ≤0.025 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarfin bayarwa Mpa | Ƙarawa % | Ƙimar tasiri (J) -60℃ |
| An Garanti | ≥490 | ≥390 | ≥22 | ≥27 |
Yaɗuwar sinadarin hydrogen a cikin ƙarfe da aka ajiye: ≤6.0mL/100g (hanyar glycerin) ko ≤10mL/100g (hanyar chromatography ta mercury ko gas)
Duba X-ray: I maki
Shawarar da ake bayarwa:
| (mm) Diamita na sanda | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Walda na Wuta | 40 ~ 70 | 60 ~ 90 | 100 ~ 120 | 140 ~ 170 | 170 ~ 200 |
Sanarwa:
1. Dole ne a gasa wutar lantarki na tsawon awa 1 a zafin 350℃ kafin a fara aiki da walda;
2. Yana da mahimmanci a tsaftace tsatsa, ma'aunin mai, ruwa, da ƙazanta a kan sassan walda kafin walda;
3. Ana iya kunna ɓangaren da aka haɗa a wuta a zafin da ya kai kimanin digiri 150 na Celsius kafin a yi walda domin hana tsagewa.
