1. Cov ntsiab lus txhais thiab cov qauv
12Crmog yog lub chromium - molybdenum alloy boiler raj hauv GB / T 5310 tus qauv. "12" Sawv cev rau cov ntsiab lus carbon ntawm 0.08-}}}}}}}}}. Piv rau qhov qub chromium-molybdenum hlau, nws cov sulfur cov ntsiab lus yog ntau dua los yog sib npaug rau kev tsim cov hluav taws xob siab hauv cov fais fab nroj tsuag.
2. Cov ntsiab lus kev ua tau zoo
Thaum tshav kub kub ua: tuaj yeem ua haujlwm ntawm 560℃rau lub sijhawm ntev thiab 600℃rau lub sijhawm luv luv.
Lub zog: Chav chav kub tensile lub zog ntau dua los yog sib npaug rau 410, 550℃siab dua los yog sib luag rau 200 MPa.
Oxidation tsis kam: chromium cov ntaub ntawv ntom xim oxide yeeb yaj kiab, muab cov pa loj dua rau cov roj carbon hlau.
Kev ua tiav: Yuav tsum muaj preheating rau 200 -}}}} 250℃rau vuam, taug kev los ntawm post-weld tempering ntawm 680-720 degree.
3. Cov ntawv thov raug
Cov ntawv thov MAIN:
Subcritical zog cog burter boiler Superheater leeg
Cov roj crushing unit rauv leeg
High - kub thiab high -}} siab cov ntxig cov tshuab piping
Qhov siab tseem ceeb - Cov kabmob sib txuas rau kev thauj khoom thaum tshav kub kub.
4. Sib Piv nrog cov ntaub ntawv zoo sib xws
Piv rau 15crmoge:
Txo cov ntsiab lus chromium (12Crmog: 0.9-1.2% vs . 15} crmog: 1.2-1.6%)
Kwv yees li ntawm 8-12% nqi txo
Kwv yees li 20-30℃qis ua haujlwm kub piv rau T12 Hlau:
Qhov sib ntxiv ntawm molybdenum txhim kho siab - kub lub zog.
Kev cuam tshuam cov tawv muaj zog yog nce los ntawm ntau dua 15%.
5. Cov ntsiab lus tseem ceeb rau kev tshaj tawm thiab kev lees txais
Cov Ntaub Ntawv Txuj Ci: Cov ntawv pov thawj ntaub ntawv suav nrog kev ntsuam xyuas kev xeem corrosion yog tseev kom muaj.
Kev Tshuaj Ntsuam Kev: 100% Ultrasonic sim + 10}}}}} eddy kev sim.
Cov khoom lag luam nto: Tsis muaj khawb ntau tshaj 0.1mm tob ntawm sab hauv thiab sab nraud chaw.
