I-AWS A5.5 E9015-B9

Incazelo: I-R717 i-electrode yensimbi engashisi ene-low-hydrogen sodium coating equkethe u-9% Cr - 1% Mo-V-Nb.Sebenzisa i-DCEP (i-electrode yamanje eqondile) futhi ingashiselelwa kuzo zonke izikhundla.Ngenxa yokwengezwa kwenani elincane le-Nb ne-V, insimbi efakiwe inokumelana okuhle kakhulu nokushisa okuphezulu.

 

Isicelo: Isetshenziselwa ukushisela amashubhu ashisa kakhulu namakhanda ama-boilers ashisa kakhulu kanye nomfutho ophezulu wegazi, njenge-A213-T91/A335-P1 (T/P91), A387Cr, 91 nezinye izakhiwo zensimbi ezikwazi ukumelana nokushisa.

Isaziso:

1. I-electrode kufanele ibhakwe ihora elingu-1 ku-350 ℃ ngaphambi kokusebenza kokushisela;

2. Kubalulekile ukuhlanza okugqwalile, isikali sikawoyela, amanzi, nokungcola ezingxenyeni zokushisela ngaphambi kokushisela.

3. Shisisa ingxenye ye-weld ku-200 ~ 260 ° C ngaphambi kokushisela, futhi ugcine izinga lokushisa elihambisanayo le-interpass;

4. Phola kancane uye ku-80 ~ 100°C amahora ama-2 ngemva kokushisela;uma ukwelashwa kokushisa kungenziwa ngokushesha ngangokunokwenzeka, ukwelashwa kwe-dehydrogenation kungenziwa ku-350 ° CX ​​2h.
