IZICELO:
Ukushisela kwezinsimbi ezingu-9% Cr-1% Mo kanye no-9% Cr – 2% Mo steels ezisetshenziselwa amandla kagesi nomkhumbi womfutho ophezulu.
INCAZELO:
I-PA-8016-B8 iyi-electrode ephansi ye-hydrogen insimbi yayo yokushisela iqukethe u-9% Cr-1% Mo.Idizayinelwe izinga lokushisa eliphezulu lensimbi nezinsimbi zezinsiza ezishisayo ze-hydrogen, ikakhulukazi embonini ye-petrochemical.I-electrode ingavunyelwa ngenxa yamandla ayo aphezulu, ukuqina okuhle nokumelana nokushisa okukhulu.
AMAZWI OKUSETSHENZISWA:
1. Yomisa ama-electrode ku-350-400 ° C cishe ihora elilodwa ngaphambi kokusetshenziswa futhi ugcine ama-electrode ku-100-150 ° C ngemva kokuwomisa ngokunaka ukuze ugweme umswakama.
2. Yamukela indlela yesinyathelo esibuyela emuva noma ushaye i-arc epuletini lensimbi elincane elilungiselelwe le njongo ethile ukuvimbela ama-blowholes ku-arc ukuqala.
3. Gcina i-arc ibe mfushane ngangokunokwenzeka.
4. Shisisa kuqala ku-100-150°C.Izinga lokushisa elizosetshenziswa liyahlukahluka ngokuya ngobukhulu bepuleti kanye nohlobo lwensimbi ezoshiselwa.
5. Qaphela ukuthi ungadluli okokufaka okushisa okufanele ngoba okokufaka ukushisa okudlulele kubangela ukuwohloka kwamanani omthelela namandla esivuno sensimbi yokushisela.
