I-Electrode Yokushisela Yensimbi Engamelani Nokushisa ye-Molybdenum ne-Chromium
R407
I-GB/T E6015-B3
I-AWS A5.5 E9015-B3
Incazelo: I-R407 iyi-electrode yensimbi engashisi kahle ene-hydrogen sodium coating ephansi equkethe i-2.5% Cr – 1% Mo. Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingashisiswa kuzo zonke izikhundla. Ukushisiswa kumele kushiswe ku-200 ~ 300°C ngaphambi kokushisiswa.
Isicelo: Isetshenziselwa ukushisela amapayipi okushisa okuphezulu kanye nokucindezela okuphezulu anokushisa okusebenzayo okungaphansi kuka-550°C, imishini yamakhemikhali yokwenziwa, imishini yokuqhekeka kwephethiloli, njll.
Ukwakheka kwamakhemikhali kwensimbi eshidiwe (%):
| 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 |
Izakhiwo zemishini zensimbi yokushisela:
| Into yokuhlola | Amandla okudonsa I-Mpa | Amandla okukhiqiza I-Mpa | Ukwelulwa % | Inani lomthelela (J) Izinga lokushisa elijwayelekile. |
| Kuqinisekisiwe | ≥590 | ≥490 | ≥15 | ≥47 |
| Kuhlolwe | 600 ~ 680 | ≥500 | 18 ~ 21 |
Okuqukethwe kwe-hydrogen okusakazwayo kwensimbi egciniwe: ≤4.0mL/100g (indlela ye-glycerin)
Ukuhlolwa kwe-X-ray: Ibanga lokuqala
I-current enconyiwe:
| Ububanzi benduku （mm） | 2.5 | 3.2 | 4.0 | 5.0 |
| Ukushisela Kwamanje (A) | 60 ~ 90 | 90 ~ 120 | 140 ~ 180 | 170 ~ 210 |
Isaziso:
1. I-electrode kumele ibhakwe ihora eli-1 ku-350℃ ngaphambi kokusebenza kokushisela;
2. Kubalulekile ukuhlanza izikali zikawoyela, amanzi kanye nokungcola okugqwalile ezingxenyeni zokushisela ngaphambi kokushisela.
