I-Electrode Yokushisela I-Copper kanye ne-Copper Alloy
T207
I-GB/T ECuSi-B
I-AWS A5.6 ECuSi
Incazelo: I-T207 iyi-electrode ye-alloy yethusi ene-silicon bronze core kanye ne-hydrogen sodium coating ephansi. Sebenzisa i-DCEP (i-electrode yamanje eqondile) enezakhiwo ezinhle kakhulu zemishini. Inokumelana okuhle kokugqwala kuma-asidi angaphili ngaphandle kwe-nitric acid, ama-asidi amaningi e-organic kanye namanzi olwandle.
Isicelo: Ifanele ukushisela ithusi, ithusi le-silicon kanye nethusi, ukushisela okungaphezulu kwezintambo zamapayipi emishini yamakhemikhali, njll.
Ukwakheka kwamakhemikhali kwensimbi eshidiwe (%):
| Cu | Si | Mn | Pb | I-Al+Ni+Zn |
| ＞92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Izakhiwo zemishini zensimbi yokushisela:
| 试验项目 Into yokuhlola | 抗拉强度 Amandla okudonsa I-Mpa | 延伸率 Ukwelulwa % |
| 保证值 Kuqinisekisiwe | ≥270 | ≥20 |
I-current enconyiwe:
| Ububanzi benduku （mm） | 3.2 | 4.0 | 5.0 |
| Ukushisela Kwamanje (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Isaziso:
Izinyathelo zokuzivikela:
1. I-electrode kumele ibhakwe cishe ku-300°C ihora eli-1 kuya kwamabili ngaphambi kokushisela;
2. Umswakama, uwoyela, ama-oxide kanye nokunye ukungcola okusebusweni be-weldment kumele kususwe ngaphambi kokushisela.
3. Lapho kushiselwa ithusi le-silicon noma ukushiselwa okungaphezulu kwensimbi, akudingeki ukushiselwa kwangaphambili. Izinga lokushisa lokushisa kusengaphambili lokushiselwa ithusi elihlanzekile lingaba ngu-450°C, kanti izinga lokushisa lokushisa kusengaphambili lokushiselwa ithusi lingaba ngu-300°C;
4. Ukushisela okufushane kufanele kusetshenziswe ngesikhathi sokushisela. Ngesikhathi sokushisela okunezingqimba eziningi, i-slag phakathi kwezingqimba kumele ibe
isuswe ngokuphelele; ngemva kokushisela, shaya i-weld ngesando sekhanda esiyisicaba ukuze ucwenge okusanhlamvu, ususe ukucindezeleka, futhi uthuthukise amandla kanye nokuqina kwe-weld.
