Bayani: A902 wani lantarki ne na bakin karfe wanda ke da rufin titanium-calcium. Ana iya amfani da shi don AC da DC tare da kyakkyawan aikin aiki. Karfe da aka ajiye yana da kyakkyawan juriya ga tsatsa da juriya ga iskar shaka kuma ana amfani da shi sosai wajen kera masana'antar sinadarai, man fetur, da kayan aikin samar da hydrogen.
Aikace-aikace: Ana amfani da shi don walda ƙarfe mai ƙarfe mai kama da Carpenter20Cb a cikin sinadarin sulfuric acid, nitric acid, phosphoric acid da kuma sinadarin oxidative acid. Haka kuma ana iya amfani da shi don walda ƙarfe daban-daban.
Sinadarin sinadarai na ƙarfen walda(%):
| C | Si | Mn | Cr | Ni | Mo | Cu | Nb | S | P |
| ≤0.07 | ≤0.60 | 0.5 ~ 2.5 | 19.0 ~ 21.0 | 32.0 ~ 36.0 | 2.0 ~ 3.0 | 3.0 ~ 4.0 | 8 XC ~ 1.00 | ≤0.030 | ≤0.030 |
Kayan aikin injiniya na ƙarfe na walda:
| Gwaji abu | Ƙarfin tauri Mpa | Ƙarawa % |
| An Garanti | ≥550 | ≥30 |
Shawarar da ake bayarwa:
| Diamita na sanda (mm) | 2.5 | 3.2 | 4.0 |
| Walda na Wuta (A) | 50 ~ 80 | 80 ~ 110 | 110 ~ 160 |
Sanarwa:
- Dole ne a gasa wutar lantarki na tsawon awa 1 a kusan 150℃ kafin a fara aikin walda;
- Saboda zurfin shigar ciki ba shi da zurfi yayin walda ta AC, ya kamata a yi amfani da wutar lantarki ta DC gwargwadon iyawa don samun zurfin shigar ciki. Kuma kada wutar ta yi girma sosai don guje wa jajayen sandar walda.
