Kev piav qhia: R306 yog lub hlau electrode pearlitic uas tiv taus cua sov nrog lub txheej potassium hydrogen tsawg uas muaj 1% Cr - 0.5% Mo. Ob qho tib si AC thiab DC tuaj yeem siv tau, thiab tuaj yeem vuam rau txhua qhov chaw. Lub vuam yuav tsum tau preheated rau 160 ~ 250 ° C ua ntej vuam.

Daim Ntawv Thov: Siv rau kev vuam Cr 1% - Mo 0.5% cov hlau uas tiv taus cua sov uas nws qhov kub ua haujlwm qis dua 520 ℃, xws li cov kav dej boiler, cov hlab ntsha siab, cov khoom siv vaporizers thiab cov khoom siv roj av refining, thiab lwm yam.

Daim Ntawv Ceeb Toom:

1. Lub electrode yuav tsum tau ci rau 1 teev ntawm ib ncig ntawm 350 ℃ ua ntej welding 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.
