Molybdenum ndi Chromium Molybdenum Wowotcherera Chitsulo Chosatentha ndi Kutentha
R407
GB/T E6015-B3
AWS A5.5 E9015-B3
Kufotokozera: R407 ndi electrode yachitsulo yolimba komanso yosatentha yokhala ndi chofunda chochepa cha haidrojeni sodium chokhala ndi 2.5% Cr - 1% Mo. Gwiritsani ntchito DCEP (electrode yamagetsi yolunjika) ndipo ikhoza kulumikizidwa m'malo onse. Cholumikiziracho chiyenera kutenthedwa mpaka 200 ~ 300°C musanachilumikize.
Kugwiritsa Ntchito: Kugwiritsidwa ntchito powotcherera mapaipi otentha kwambiri komanso opanikizika kwambiri okhala ndi kutentha kochepera 550°C, makina opangira mankhwala, zida zophwanyira mafuta, ndi zina zotero.
Kapangidwe ka mankhwala a chitsulo chosungunula (%):
| C | Mn | Si | Cr | Mo | S | P |
| 0.05 ~ 0.12 | 0.50 ~ 0.90 | ≤0.50 | 2.00 ~ 2.50 | 0.90 ~ 1.20 | ≤0.030 | ≤0.030 |
Kapangidwe ka makina a chitsulo chosungunula:
| Chinthu choyesera | Kulimba kwamakokedwe Mpa | Mphamvu yobereka Mpa | Kutalikitsa % | Mtengo wa zotsatira (J) Kutentha Kwabwinobwino. |
| Chotsimikizika | ≥590 | ≥490 | ≥15 | ≥47 |
| Yayesedwa | 600 ~ 680 | ≥500 | 18 ~ 21 |
Kuchuluka kwa haidrojeni m'chitsulo chosungidwa: ≤4.0mL/100g (njira ya glycerin)
Kuwunika kwa X-ray: Giredi I
Mphamvu yovomerezeka:
| M'mimba mwake wa ndodo (mm) | 2.5 | 3.2 | 4.0 | 5.0 |
| kuwotcherera Current (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Zindikirani:
1. Electrode iyenera kuphikidwa kwa ola limodzi pa kutentha kwa 350℃ isanayambe kuwotcherera;
2. Ndikofunikira kuyeretsa dzimbiri, mafuta oyeretsera, madzi, ndi zinyalala pa zipangizo zowotcherera musanawotchetse.
