15CrMoG alloy yeeb nkabyog cov khoom siv steel yeeb nkab nrog kev ua haujlwm kub zoo thiab cov khoom siv kho tshuab. Cov yeeb nkab steel hlau no muaj kev tiv thaiv oxidation zoo heev thiab lub zog kub ntawm qhov kub thiab txias, thiab tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev hauv qhov kub thiab txias. Qhov no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim hluav taws xob siab boilers thiab lwm yam khoom siv.
15CrMoG alloy boiler raj kuj tseem muaj kev nkag siab zoo, uas yog, nws tuaj yeem ua nws cov yam ntxwv ua haujlwm ruaj khov hauv qee cov khoom siv uas ua haujlwm ntawm qhov kub thiab txias rau lub sijhawm ntev, ua rau lub neej ua haujlwm ntawm cov cuab yeej siv tau ntev thiab txhim khu kev qha.
Thiab vim muaj lub zog siab thiab corrosion tsis kam ntawm 15CrMoG seamless boiler hlab, hauv kev tsim khoom ntawm qee cov khoom siv siab, kev siv cov yeeb nkab steel ua los ntawm cov khoom siv alloy no tsis tsuas yog txhim kho cov khoom siv, tab sis kuj txo cov nqi tu. ntawm cov khoom siv.

15CrMoG steel yeeb nkab ua raws li GB 5310-95 tus qauv thiab sib npaug rau 13CrMo44 ntawm Tsoom Fwv Teb Chaws Republic of Germany thiab sib npaug rau 1Cr-1/2Mo thiab 1 1/4cr-1 /2mo-si steel qib feem ntau siv thoob ntiaj teb). Ib qho tseem ceeb feature yog nws cov ntsiab lus chromium siab. Qhov no tso cai rau nws ua kom pom lub zog thermal zoo hauv qhov kub thiab txias ntawm 500-550 degree . Txawm li cas los xij, thaum qhov kub siab tshaj qhov no, nws qhov kev siv thermal txo qis sai. Nyob rau hauv ib tug nruam 500-550 degree ib puag ncig, txawm hais tias graphitization yuav tsis tshwm sim, carbide spheroidization thiab redistribution ntawm alloy ntsiab yog inevitable, uas yuav undoubtedly cuam tshuam lub thermal zog ntawm hlau. Nws tseem tsim nyog taw qhia tias 15CrMoG steel nthuav tawm cov khoom zoo los tiv thaiv kev so ntawm 450 degree thiab yooj yim los ua cov kav dej thiab vuam.
