  • AWS E9015-B9 Usha Alxanka ee Arc-ka ah ee aan la xidhi karin ee Elektrodes-ka buuxinta Birta

AWS E9015-B9 Usha Alxanka ee Arc-ka ah ee aan la xidhi karin ee Elektrodes-ka buuxinta Birta

Sharaxaad Gaaban:

R717 (AWS E9015-B9) waa elektarood bir ah oo kulaylka u adkaysta oo leh dahaadh sodium oo haydarojiin yar leh oo ka kooban 9% Cr – 1% Mo-V-Nb.

AWS A5.5 E9015-B9

Sharaxaad: R717 waa elektarood bir ah oo kulaylka u adkaysta oo leh dahaar sodium oo hooseeya oo ka kooban 9% Cr – 1% Mo-V-Nb. Isticmaal DCEP (elektaroodka hadda tooska ah ee togan) waxaana lagu dhejin karaa dhammaan boosaska. Sababtoo ah qadar yar oo Nb iyo V ah, birta la dhigay waxay leedahay iska caabin heerkul sare oo aad u fiican.

 

Codsiga: Waxaa loo isticmaalaa alxanka tuubooyinka aadka u kulul iyo madaxyada kuleyliyaha heerkulka sare iyo cadaadiska sare, sida A213-T91/A335-P1 (T/P91), A387Cr, 91 iyo qaabab kale oo bir ah oo u adkaysta kulaylka.

Ogeysiis:

1. Elektroodka waa in la dubo 1 saac heerkul ah 350℃ ka hor inta aan la isticmaalin alxanka;

2. Waa lagama maarmaan in la nadiifiyo miridhku, miisaanka saliidda, biyaha, iyo wasakhda ku jirta qaybaha alxanka ka hor inta aan la alxanka.

3. Kuleyli qaybta alxanka 200 ~ 260°C ka hor intaadan alxanka sameyn, oo ilaali heerkulka u dhigma ee dhexda;

4. Si tartiib ah u qabooji ilaa 80 ~ 100°C muddo 2 saacadood ah ka dib alxanka; haddii daaweynta kulaylka aan la samayn karin sida ugu dhakhsaha badan, daaweynta fuuq-baxa waxaa lagu samayn karaa 350°CX 2 saacadood.
