1.Dab tsi yogsteel boiler phaj?
Boiler steel daim hlau feem ntau yog xa mus rau kub- dov nruab nrab- cov ntaub ntawv tuab phaj siv los tsim cov superheaters, cov kav dej loj thiab cov boiler firebox cua sov. Boiler steel phaj yog ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kev tsim boiler. Nws feem ntau yog hais txog kub- dov tshwj xeeb carbon steel thiab tsis tshua muaj alloy siv los tsim cov khoom tseem ceeb xws li lub lauj kaub plhaub, nruas, hau npog, kev txhawb nqa thiab cov hangers hauv boilers. Thaum tshav kub kub-resistant steel nruab nrab- tuab steel phaj khoom.
2.Boiler steel phaj khoom
Cov ntaub ntawv tseem ceeb ntawm boiler steel muaj xws li siab-cov qauv hlau zoo thiab qis- alloy kub- cov hlau tsis muaj zog. Feem ntau siv boiler steels muaj xws li qis- carbon tua steel smelted los ntawm qhib-heart furnaces los yog qis- carbon steel smelted los ntawm hluav taws xob furnaces. Cov ntsiab lus carbon Wc yog nyob rau hauv thaj tsam ntawm 0.16%-0.26%. Txij li thaum lub boiler steel phaj ua hauj lwm nyob rau hauv nruab nrab kub (qis dua 350ºC) thiab siab siab, ntxiv rau bearing siab, nws kuj yuav raug cuam tshuam, qaug zog load thiab dej thiab roj corrosion. Cov kev ua tau zoo ntawm boiler steel yog qhov zoo tshaj plaws vuam thiab txias dabtsi yog khoov zog. Tej yam kub kub lub zog thiab tsis kam mus rau alkali corrosion, oxidation, thiab lwm yam. Boiler steel phaj feem ntau ua hauj lwm nyob rau hauv nruab nrab-siab kub thiab siab. Ntxiv nrog rau kev tiv taus qhov kub thiab txias, lawv kuj raug cuam tshuam rau kev qaug zog loads thiab dej thiab roj corrosion. Cov xwm txheej ua haujlwm tsis zoo. Yog li ntawd, boiler steel daim hlau yuav tsum muaj lub cev zoo, txhua yam khoom thiab durability. Processability kom muaj kev ruaj ntseg ntawm cov khoom siv.
3. Kev faib tawm ntawm boiler steel daim hlau
Hais txog cov ntaub ntawv, boiler steel daim hlau yuav muab faib ua ob pawg: tshwj xeeb carbon steel daim hlau thiab tsis tshua muaj alloy tshav kub-resistant steel daim hlau. Cov ntaub ntawv siv hauv boiler steel daim hlau muaj kev tswj xyuas nruj ntawm lawv cov tshuaj muaj pes tsawg leeg, tshwj xeeb tshaj yog cov teeb meem xws li phosphorus thiab sulfur thiab cov khoom seem xws li chromium, nickel thiab tooj liab. Kev deoxidation zoo thiab tshem tawm cov tsis yog -cov khoom siv hlau yuav tsum tau ua thaum lub sij hawm smelting kom zoo Plasticity thiab toughness; lub microstructure yuav tsum tau sib xws, thiab cov nplej loj yog tswj nyob rau hauv ib tug tej yam ntau yam (feem ntau lub grain loj yuav tsum nyob nruab nrab ntawm 3 thiab 7); tseem muaj cov kev cai nruj rau qhov zoo ntawm qhov chaw thiab qhov tsis xws luag; Tsis tas li ntawd, txhua yam khoom ntawm chav tsev kub thiab kub siab yuav tsum tau lav.
Nws txawv raws li kev ua haujlwm. Boiler steel daim hlau tuaj yeem muab faib ua ob pawg: steel phaj rau chav tsim khoom- kub thiab nruab nrab- kub siab- cov kabmob thiab cov phaj hlau rau kev tsim khoom siab - qhov kub siab - cov kabmob.

13CrMo4-5, 1.7335 - Cov yam ntxwv thiab daim ntawv thov
13CrMo4-5 cov hlau tsis tshua muaj hlau tsis tshua muaj qis- carbon chrome-molybdenum qib piv rau lwm cov qib siab kub, uas muaj qhov ua haujlwm zoo txias thiab kub ua haujlwm, zoo heev machinability, weldability thaum tuav lub zog siab ntawm chav tsev kub thiab siab kub.
Qhov sib npaug ze tshaj ntawm 13CrMo4-5, feem ntau pom nyob rau hauv daim ntawv ntawm cov khoom, yog siv los ua ib nrab - cov khoom tiav rau cov khoom thiab cov khoom siv hluav taws xob rau kev lag luam hluav taws xob, nrog rau kev lag luam chemical uas ua haujlwm kub txog 530℃- nyob rau hauv kev sib cuag nrog cov kua yuav muaj ntau yam concentrations ntawm "cov khoom siv zog" thiab cov khoom siv roj. Cheebtsam, boilers, turbines thiab fais fab system.
Hauv qib 13CrMo4-5 qib yog tsim rau cov khoom siv rau kev teeb tsa - hauv qab, flanges, hauv caug, tees, profiles, seamless raj, nrog rau cov tuav, forgings, tiaj tus tuav thiab cov ntawv kub dov nrog ntau yam tuab thiab qhov ntev. Yav dhau los hais txog fittings yog siv rau chav thiab lwm yam paug tawm, xws li cov kav dej thiab cov kav dej superheater.
Rau kub dov, forgings, thiab forged cov ntaub ntawv, cov khoom no yog siv rau screws, ceev, struts thiab qhov chaw ntawm boilers thiab chav turbines. Cov khoom lag luam tiaj tus - xws li daim hlau los yog daim kab xev yog siv los ua cov khoom siv rau cov hlab ntsha siab, cov hniav turbine, steamers los yog cov khoom ntim khoom.
