AWS: SFA 5.5 E9015-B3Cov electrodes rau cov hlau uas tiv taus kev nkag

Cov hlau txuas hydrogen tsawg uas muaj 2.25Cr – 1Mo tso rau hauv cov hlau txuas, ua rau pom tias muaj zog o thiab tiv taus qhov nkag ntawm qhov kub siab txog li 575 C. Nws yog siv rau kev txuas 21/4 Cr-1 Mo cov hlau uas tiv taus qhov nkag thiab Cr-Mo-V cov hlau uas tiv taus hydrogen hauv qab siab nrog rau cov hlau cam khwb uas muaj cov khoom zoo sib xws rau cov hlau txuas. Cov ntawv thov ib txwm muaj xws li kev tsim lub boiler chav, kev txuas cov kav dej chav thiab cov kav dej kub loj, cov chaw tsim hluav taws xob, chaw tsim roj thiab cov chaw tsim tshuaj lom neeg.

Kev ceev faj

1. Rov ua kom cov electrodes qhuav ntawm 250-300 C rau ib teev, raws li peb cov qauv kev coj ua.

2. Siv cov hlaws luv luv thiab cov hlaws stringer.
