Electrode alxanka Alloy Low
J557SLA, J557SLB
GB/T E5515-G
AWS E8015-G
Sharaxaad: Kani waa soodhiyam haydaroojin hooseeya oo daboosha elektirode gaar ah oo loogu talagalay birta aluminiumka ah.Isticmaal DCEP (electrode toos ah oo toos ah), waxaana lagu alxan karaa dhammaan boosaska leh qalliinka fallaadha gaaban.J557SLA si toos ah ayaa loo alxan karaa iyada oo aan la saarin lakabka aluminium ee dusha jeexdin ka hor alxanka.Laakiin J557SLB waa in ay ka saartaa lakabka aluminiumka ah ee dusha sare ee jeexdin ka hor alxanka.
Codsiga: Waxaa loo isticmaalaa alxanka qaab-dhismeedka birta aluminium ee hoos yimaada dhexdhexaadinta daxalka ee hydrogen sulfide, sulfur, ammonia, ammonium bicarbonate iyo nitrogen nitrogen leh heerkulka shaqada ee ka hooseeya 540 ° C.Sida tuubooyinka kululeeyaha, qalabka sifaynta batroolka, qalabka bacriminta iyo tubooyinka uumiga, iwm.
Halabuurka kiimikada ee birta alxanka (%):
| C | Mn | Si | Cr | Mo | Al | S | P |
| ≤0.12 | 0.50 ~ 0.90 | ≤0.50 | ≈0.80 | ≥0.20 | ≤0.055 | ≤0.035 | ≤0.035 |
Qalabka makaanikada ee birta alxanka:
| Shayga tijaabi | Xoog xajin Mpa | Xoog soo saar Mpa | Dheeraynta % | Qiimaha saamaynta (J) Heerkulka caadiga ah |
| La damaanad qaaday | ≥540 | ≥440 | ≥17 | ≥49 |
Mawduuca hydrogen firidhsan ee birta kaydsan: ≤6.0mL/100g (hab glycerin)
Kormeerka raajada: Waxaan darajo
Hadda lagu taliyay:
| (mm) Dhexroor usheeda | 2.5 | 3.2 | 4.0 | 5.0 |
| (A) Alxanka Hadda | 50 ~ 80 | 80 ~ 110 | 130 ~ 170 | 160 ~ 200 |
Ogaysiis:
1. Electrode waa in lagu dubaa 1 saac agagaarka 350 ℃ ka hor alxanka;
2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda qaybaha alxanka ka hor.
