Daim ntawv thov & Standard & Ceeb toom:

AWS E7015-B2L tshav kub resistant steel electrode yog tsim rau vuam boiler cua sov nto raj thiab fais fab nroj tsuag dej phab ntsa, chav yeeb nkab thiab siab siab hlab ntsha ua hauj lwm kub hauv qab no 550 ℃, xws li 15CrMo raj phaj, A335-P11 raj, A387Gr.11 phaj. Thiab tuaj yeem siv rau 30CrMnSi casting vuam, haum rau lub sijhawm ntawm cov ntsiab lus qis carbon. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tau preheat qhov vuam ntawm qhov sib txuas ntawm qhov kub ntawm 160 ℃ ~ 190 ℃ thaum vuam, thiab 690 ± 15 ℃ * 1h kev kho cua sov yuav tsum tau ua raws li cov qauv kev cai ntawm cov khoom siv vuam.

Nta

AWS E7015-G2L(R307L) hom kub-resistant steel tes electrode yog ib qho tsis tshua muaj sodium hydrogen hom tes electrode, ruaj khov arc, tsis tshua muaj txaws, zoo tsim, yooj yim desagging, X-Ray kev ua tau zoo heev. Nws muaj cov khoom siv kho tshuab ruaj khov thiab tuaj yeem tswj tau qhov cuam tshuam siab toughness nyob rau hauv kev kho cua sov. Preheating yog ib qho kev ntsuas tseem ceeb rau kev vuam cov kab nrib pleb txias thiab tshem tawm kev ntxhov siab ntawm perlite tshav kub resistant steel. Txhawm rau kom ntseeg tau qhov zoo ntawm vuam, tsis muaj teeb meem nyob rau hauv cov txheej txheem ntawm cov khoom siv vuam lossis vuam, nws yuav tsum tau preheated thiab tswj qhov kub thiab txias. Tom qab qhov kawg ntawm kev ua haujlwm vuam mus rau vuam qeeb qeeb, vuam qeeb qeeb yog vuam chromium-molybdenum tshav kub resistant steel yuav tsum nruj me ntsis raws li txoj cai, txawm nyob rau lub caij ntuj sov kub yuav tsum ua li no, dav dav vuam tam sim ntawd nrog asbestos ntaub los npog lub vuam thiab nyob ze ntawm qhov chaw seam, me me vuam qhov chaw tuaj yeem muab tso rau hauv cov ntaub asbestos qeeb qeeb.
