Electrode yo gusudira ikoresheje umuringa n'umuringa
T207
GB/T ECuSi-B
AWS A5.6 ECuSi
Ibisobanuro: T207 ni electrode y'umuringa ifite silicon bronze core na hydrogen sodium coating nkeya. Koresha DCEP (electrode y'amashanyarazi ifatika) ifite imiterere myiza ya mekanike. Ifite ubudahangarwa bwiza bwo kwangirika ku bindi binyabutabire bitari aside nitrike, aside organic nyinshi n'amazi yo mu nyanja.
Ikoreshwa: Ikwiriye gusudira umuringa, silicon bronze na brasse, gusudira hejuru y'imiyoboro y'imashini za shimi, n'ibindi.
Imiterere ya shimi y'icyuma gisukwa (%):
| Cu | Si | Mn | Pb | Al+Ni+Zn |
| ＞92.0 | 2.5 ~ 4.0 | ≤3.0 | ≤0.02 | ≤0.50 |
Imiterere ya tekiniki y'icyuma gisudira:
| 试验项目 Ikintu cyo kugerageza | 抗拉强度 Imbaraga zo gukurura Mpa | 延伸率 Kurekura % |
| 保证值 Yemejwe | ≥270 | ≥20 |
Ikoreshwa ry'amashanyarazi risabwa:
| Umwanya w'inkoni (mm) | 3.2 | 4.0 | 5.0 |
| Umuyoboro wo gusudira (A) | 90 ~ 130 | 110 ~ 160 | 150 ~ 200 |
Itangazo:
Amabwiriza yo kwirinda:
1. Electrode igomba gutekwa ku bushyuhe bwa dogere selisiyusi 300 mu gihe cy'isaha 1 kugeza kuri 2 mbere yo gusudira;
2. Ubushuhe, amavuta, okiside n'indi myanda iri ku buso bw'aho gusudira bigomba gukurwaho mbere yo gusudira.
3. Mu gusudira umuringa wa silikoni cyangwa gusudira hejuru ku cyuma, nta gushyushya gukenewe. Ubushyuhe bwo gusudira umuringa mwiza ni hafi 450°C, naho ubushyuhe bwo gusudira umuringa ni hafi 300°C;
4. Gusudira mu buryo bugufi bigomba gukoreshwa mu gihe cyo gusudira. Mu gihe cyo gusudira mu buryo bw'ibyiciro byinshi, slag hagati y'ibyiciro igomba kuba
gukuraho burundu; nyuma yo gusudira, koresha inyundo irambuye mu gusudira kugira ngo utunganye ibinyampeke, ukureho stress, kandi wongere imbaraga n'ubudahangarwa bw'isudi.
