I-Electrode Yokushisela I-Nickel ne-Nickel Alloy
I-Ni327-4
I-GB/T ENi6276
I-AWS A5.11 ENiCrMo-4
Incazelo: I-Ni327-4 iyi-electrode esekelwe ku-nickel ene-hydrogen sodium coating ephansi. Sebenzisa i-DCEP (i-electrode yamanje eqondile)okuhle). Isebenza kahle kakhulu ngokushisela ngokushisa okuzinzile kwe-arc, ukuchitheka okuncane, ukususa i-slag kalula,
kanye nokushisela okuhle. Izakhiwo zemishini zensimbi egciniwe zizinzile.
Ukusetshenziswa: Isetshenziselwa ukushisela ama-alloy e-nickel-chromium-molybdenum anekhabhoni ephansi, njenge-Hastelloy C276, ASTM B574, B575, B619, B622, B626, futhi ingasetshenziswa futhi ekushiseleni izinsimbi ezingafani nezinye ama-alloy asekelwe ku-nickel.
Ukwakheka kwamakhemikhali kwensimbi eshidiwe (%):
| C | Mn | Si | Cr | Ni | Mo |
| ≤0.02 | ≤1.0 | ≤0.2 | 14.5 ~ 16.5 | ≥50.0 | 15.0 ~ 17.0 |
| W | Co | Fe | S | P | Okunye |
| 3.0 ~ 4.5 | ≤2.5 | 4.0 ~ 7.0 | ≤0.015 | ≤0.020 | ≤0.5 |
Izakhiwo zemishini zensimbi yokushisela:
| Into yokuhlola | Amandla okudonsa I-Mpa | Amandla okukhiqiza I-Mpa | Ukwelulwa % |
| Kuqinisekisiwe | ≥690 | ≥400 | ≥22 |
I-current enconyiwe:
| Ububanzi benduku （mm） | 2.5 | 3.2 | 4.0 |
| Ukushisela okwamanje (A) | 60 ~ 90 | 70 ~ 110 | 90 ~ 150 |
Isaziso:
1. I-electrode kumele ibhakwe ihora eli-1 cishe ku-300℃ ngaphambi kokusebenza kokushisela. Zama ukusebenzisa i-arc emfushane ukushisela;
2. Kubalulekile ukuhlanza okugqwalile, uwoyela, amanzi, kanye nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.
3. Zama ukusebenzisa amandla amancane lapho ushisela, ushisela onamaleya amaningi kanye noshisela onamaphasi amaningi.
