Q: Vim li cas kev kho cua sov yog qhov tseem ceeb rau 12Cr1MoVG thiab 15CrMoG kav?
A:Kev kho cua sov kom zoo (normalizing thiab tempering) yog qhov tseem ceeb kom ua tiav qhov xav tau microstructure. Nws optimizes cov khoom siv kho tshuab, ua kom muaj kev ruaj ntseg thaum lub sij hawm siab - qhov kub thiab txias, thiab txhim khocreep kuj-2.
Q: Lub zog creep yog dab tsi, thiab vim li cas nws tseem ceeb rau cov ntaub ntawv no?
A:Creep yog qhov qeeb, mus tas li deformation ntawm cov khoom nyob rau hauv qhov kev ntxhov siab tas li ntawm qhov kub thiab txias. Siabcreep zogNws yog ib qho tseem ceeb rau boiler thiab piping Cheebtsam los tiv thaiv tsis ua hauj lwm ntau xyoo ntawm kev pab cuam. Piv txwv li, qib P91/P92 muaj kev ua tau zoo tshaj plaws-1.
Q: Txog li cas qhov kub thiab txias tuaj yeem siv 12Cr1MoVG tsis tu ncua?
A:12Cr1MoVG tuaj yeem siv tau ntev -kev pabcuam hauv qhov kub thiab txias mus txog580 degree, thaum nws tuaj yeem tiv taus kub txog 650℃rau lub sijhawm luv-4.
Q: 15CrMoG ua li cas nyob rau hauv cov cua kub thiab txias txias?
A:Cov alloy muaj pes tsawg leeg ntawm 15CrMoG muab kev tiv thaiv zoo rau thermal qaug zog, tso cai rau nws ua tau zoo nyob rau hauv cyclic thermal stresses feem ntau ntsib hauv boilers thiab cov txheej txheem cua sov.
Q: Thaum twg yuav tsum xaiv 12Cr1MoVG tshaj 15CrMoG?
A: 12Cr1MoVGfeem ntau nyiam rau cov ntawv thov uas xav tau siab duacreep zogthiabthermal stabilityntawm qhov kub siab heev (piv txwv li, ntu superheater).15 CrMoGyog qhov kev xaiv zoo tshaj plaws rau siab -kub siv qhov twg zoohydrogen corrosion kujthiabweldabilityyog cov kev txhawj xeeb tseem ceeb-1-7.
