AWS A5.5 E9015-B9

Kev piav qhia: R717 yog lub electrode hlau uas tiv taus cua sov nrog lub txheej sodium hydrogen tsawg uas muaj 9% Cr - 1% Mo-V-Nb. Siv DCEP (direct current electrode positive) thiab tuaj yeem welded rau txhua qhov chaw. Vim yog ntxiv me ntsis Nb thiab V, cov hlau uas tau tso rau hauv muaj kev tiv taus kub zoo heev.

 

Daim Ntawv Thov: Nws yog siv rau kev vuam cov kav dej superheated thiab cov taub hau ntawm cov boilers kub thiab siab, xws li A213-T91 / A335-P1 (T / P91), A387Cr, 91 thiab lwm yam hlau tiv taus cua sov.

Daim Ntawv Ceeb Toom:

1. Lub electrode yuav tsum tau ci rau 1 teev ntawm 350 ℃ ua ntej vuam ua haujlwm;

2. Nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov xeb, cov roj, dej, thiab cov khoom tsis huv ntawm cov khoom vuam ua ntej vuam.

3. Ua ntej vuam qhov chaw vuam ntawm 200 ~ 260 ° C, thiab tswj qhov kub ntawm qhov sib tshuam;

4. Maj mam txias rau 80 ~ 100 ° C rau 2 teev tom qab vuam; yog tias kev kho cua sov tsis tuaj yeem ua tiav sai li sai tau, kev kho dehydrogenation tuaj yeem ua tiav ntawm 350 ° CX ​​2 teev.
