Kuwotcherera kwa Zitsulo Zotentha Zotsika
W707
GB/T E5015-G
AWS A5.5 E7015-G
Kufotokozera: W707 ndi electrode yachitsulo yotsika kutentha yokhala ndi chofunda chochepa cha haidrojeni sodium. Gwiritsani ntchito DCEP (electrode ya direct current positive) ndipo ikhoza kulumikizidwa m'malo onse. Chitsulo chosungidwacho chimakhalabe ndi mphamvu yabwino pa -70°C.
Kugwiritsa Ntchito: Kugwiritsidwa ntchito powotcherera zitsulo zotentha kwambiri monga 2.5Ni.
Kapangidwe ka mankhwala a chitsulo chosungunula (%):
| C | Mn | Si | Ni | S | P |
| ≤0.08 | ≤1.25 | ≤0.60 | 2.00 ~ 2.75 | ≤0.020 | ≤0.025 |
Kapangidwe ka makina a chitsulo chosungunula:
| Chinthu choyesera | Kulimba kwamakokedwe Mpa | Mphamvu yobereka Mpa | Kutalikitsa % | Mtengo wa zotsatira (J) -70℃ |
| Chotsimikizika | ≥490 | ≥390 | ≥22 | ≥27 |
Kuchuluka kwa haidrojeni m'chitsulo chosungidwa: ≤6.0mL/100g (njira ya glycerin) kapena ≤10mL/100g (njira ya mercury kapena gasi chromatography)
Kuwunika kwa X-ray: Giredi I
Mphamvu yovomerezeka:
| (mm) M'mimba mwake wa ndodo | 2.0 | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) kuwotcherera Current | 40 ~ 70 | 70 ~ 100 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Zindikirani:
1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha kwa 350℃ isanayambe kuwotcherera;
2. Yesetsani kugwiritsa ntchito mphamvu zochepa polumikiza, kulumikiza zinthu zambiri komanso kugwiritsa ntchito njira zambiri.
