Incazelo: I-R407 iyi-electrode yensimbi ekwazi ukumelana nokushisa i-pearlitic ene-low-hydrogen sodium coating equkethe u-2.5% Cr - 1% Mo. Sebenzisa i-DCEP (i-electrode eqondile yamanje eqondile) futhi ingashiselwa kuzo zonke izikhundla.I-weldment kufanele ishiswe ngaphambili ibe ngu-200 ~ 300 ° C ngaphambi kokushisela.

Isicelo: Isetshenziselwa ukushisela amapayipi okushisa aphezulu kanye nomfutho ophezulu wezinga lokushisa elingaphansi kuka-550 ° C, imishini yamakhemikhali okwenziwa, imishini yokuqhekeka ye-petroleum, njll.

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.
