Whakaahuatanga: Ko te R717 he hiko hiko wera-wera me te paninga konutai iti-hydrogen kei roto 9% Cr - 1% Mo-V-Nb.Whakamahia te DCEP (te hiko tika o naianei) ka taea te paihere ki nga waahi katoa.Na te taapiri o te iti o te Nb me te V, he pai rawa atu te parenga ngokingoki i te pāmahana teitei.

 

Taupānga: Kei te whakamahia mō te fehokotaki'anga ngongo superheated me upoko o tiketike-te pāmahana me te teitei-pēhanga boilers, pērā i A213-T91 / A335-P1 (T / P91), A387Cr, 91 me ētahi atu hanganga maitai wera-ātete.

Panui:

1. Me tunuhia te electrode mo te 1 haora i te 350 ℃ i mua i te mahi whakapiri;

2. He mea nui ki te horoi i te waikura, te unahi hinu, te wai, me nga poke i runga i nga waahanga whakapiri i mua i te whakapiri.

3. Whakawerahia te waahanga weld i te 200 ~ 260 ° C i mua i te whakapiri, me te pupuri i te pāmahana interpass e rite ana;

4. Ata whakamatao ki te 80 ~ 100°C mo nga haora 2 i muri i te whakapiri;ki te kore e taea te maimoatanga o te wera i te wa e taea ai, ka taea te whakahaere i te maimoatanga whakaheke i te 350 °CX 2h.
