GB3531 16MnDR Steel Phaj Rau Boiler Thiab Siab Nkoj

GB3531 16MnDR yog hom hlau phaj rau cov hlab ntsha uas tsis tshua muaj siab. Hauv qab no yog cov lus qhia ntxaws txog nws:

 

Tshuaj muaj pes tsawg leeg:
Cov pa roj carbon (C): Cov ntsiab lus tsawg dua lossis sib npaug rau 0.20%. Cov pa roj carbon monoxide yog ib qho tseem ceeb cuam tshuam rau lub zog thiab hardness ntawm hlau. Txawm li cas los xij, yog tias cov ntsiab lus carbon siab dhau lawm, nws yuav txo qhov toughness thiab vuam kev ua tau zoo ntawm cov hlau. Cov ntsiab lus tsis tshua muaj carbon nyob rau hauv cov hlau phaj no ua kom nws zoo toughness thiab weldability ntawm qhov kub thiab txias.
Silicon (Si): Cov ntsiab lus nyob nruab nrab ntawm 0.15 - 0.50%. Silicon, raws li lub deoxidizer, tuaj yeem txhim kho cov hlau zoo thiab tseem ua rau lub zog thiab tawv tawv ntawm cov hlau.
Manganese (Mn): Cov ntsiab lus yog 1.20 - 1.60%. Manganese yog ib qho zoo deoxidizer thiab desulfurizer, uas tuaj yeem txo cov kev phom sij ntawm cov sulfur, txhim kho cov hlau zoo, thiab tib lub sij hawm nce lub zog, tawv thiab hardenability ntawm hlau.
Phosphorus (P): Cov ntsiab lus tsawg dua lossis sib npaug rau 0.025%. Phosphorus yog ib qho teeb meem uas yuav ua rau kom txias brittleness ntawm hlau, yog li nws cov ntsiab lus yuav tsum tau tswj nruj me ntsis.
Sulfur (S): Cov ntsiab lus tsawg dua lossis sib npaug rau 0.015%. Sulfur yuav ua rau kom kub brittleness ntawm hlau thiab txo qhov toughness thiab vuam kev ua tau zoo ntawm cov hlau, yog li nws cov ntsiab lus kuj yuav tsum tau tswj nyob rau theem qis.
Aluminium (Alt): Cov ntsiab lus ntau dua lossis sib npaug rau {{0}}.02% (qee cov ntaub ntawv qhia Ntau dua lossis sib npaug rau 0.015%). Aluminium tuaj yeem ua lub luag haujlwm hauv kev kho cov nplej, txhim kho lub zog thiab tawv ntawm cov hlau.

 

Mechanical zog:
Yield zog: Nws txawv raws li lub thickness ntawm steel phaj. Rau cov hlau phaj nrog lub thickness ntawm 6 - 16 hli, lub zog tawm los yog ntau dua los yog sib npaug rau 315MPa; rau cov tuab ntawm 16 - 36mm, nws yog ntau dua los yog sib npaug rau 295MPa; rau cov thickness ntawm 36 - 60mm, nws yog ntau dua los yog sib npaug rau 275MPa; rau cov thickness ntawm 60 - 100mm, nws yog ntau dua los yog sib npaug rau 255MPa; thiab rau cov thickness ntawm 100 - 120mm, nws yog ntau dua los yog sib npaug rau 265MPa.
Tensile zog: Nws nyob nruab nrab ntawm 450 - 620MPa.
Elongation: Ntau dua lossis sib npaug li 21%, uas qhia txog lub peev xwm ntawm cov yas deformation ntawm cov hlau.
Kev ntsuam xyuas kev cuam tshuam: Ntawm qhov kub ntawm - 40 degree, qhov cuam tshuam lub zog nqus yog ntau dua lossis sib npaug rau 27J (rau qee qhov tuab, nws yuav tsum tau siab dua lossis sib npaug rau 47J), uas qhia tau tias cov phaj hlau muaj zoo toughness nyob rau hauv qis kub thiab muaj peev xwm tiv taus tej yam loads nyob rau hauv ib tug tsawg - kub ib puag ncig.

 

Lub xeev tus me nyuam: Normalized thiab tshuaj xyuas los ntawm kev kuaj ultrasonic nrog qib siab tshaj peb. Normalizing kev kho mob tuaj yeem ua rau cov qauv ntawm cov hlau phaj zoo sib xws thiab txhim kho nws cov kev ua tau zoo. Kev kuaj ultrasonic yog los xyuas kom meej tias tsis muaj qhov tsis xws luag hauv cov phaj steel thiab lav qhov zoo.

 

Daim ntawv thov: Nws yog tsuas yog siv nyob rau hauv kev tsim cov hlab ntsha siab, boilers, cia tso tsheb hlau luam, tshav kub exchangers thiab lwm yam khoom siv, thiab yog dav siv nyob rau hauv kev lag luam xws li roj av, tshuaj engineering thiab roj.

 

Hauv luv luv, GB3531 16MnDR steel phaj muaj qhov zoo ntawm qhov kub thiab txias, lub zog muaj zog thiab kev ua haujlwm vuam zoo, thiab tsim nyog rau kev tsim cov hlab ntsha siab thiab lwm yam khoom siv nyob rau hauv qhov kub thiab txias. Thaum siv cov txheej txheem, nws yog ib qho tsim nyog yuav tsum tsim, tsim thiab tshuaj xyuas nruj me ntsis raws li cov qauv thiab cov kev qhia tshwj xeeb kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv.

16MnDR steel feem ntau muaj cov hauv qab no siv:

 

Hauv kev lag luam roj av thiab tshuaj lom neeg:

 

Cov tso tsheb hlau luam uas tsis muaj qhov kub thiab txias: Lawv siv los khaws cov kua dej qis xws li cov roj av liquefied (LPG), kua nitrogen, thiab cov pa oxygen. Cov khoom ntim qis qis no yuav tsum muaj lub zog zoo thiab toughness ntawm qhov kub thiab txias. Qhov kev ua haujlwm kub qis ntawm 16MnDR steel tuaj yeem ua tau raws li qhov yuav tsum tau siv ntawm cov tso tsheb hlau luam hauv qhov chaw qis thiab tiv thaiv kev tawg tawg thaum lub sij hawm khaws cia ntawm qhov kub thiab txias.

Tshuaj lom neeg cov hlab ntsha: Hauv qee cov txheej txheem tsim tshuaj lom neeg, cov tshuaj tiv thaiv yuav tsum tau ua raws li qhov tshwj xeeb ntawm qhov kub thiab txias, xws li qee cov tshuaj tiv thaiv theem hauv cov txheej txheem tsim khoom ntawm cov khoom cua ammonia thiab methanol. 16MnDR steel tuaj yeem siv los tsim cov tshuaj tiv thaiv cov hlab ntsha hauv qhov chaw qis qis no kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem tshuaj tiv thaiv.

 

Nyob rau hauv lub zog teb:

 

Cov khoom siv roj thiab cov khoom siv thauj mus los: Thaum lub sij hawm khaws cia thiab kev thauj mus los ntawm cov pa roj, nws yuav nyob rau hauv qhov kub thiab txias. 16MnDR steel tuaj yeem siv los tsim cov khoom siv roj av, cov kav dej thauj mus los thiab lwm yam khoom siv los ua kom muaj kev nyab xeeb ntawm cov pa roj thaum lub sijhawm khaws cia thiab kev thauj mus los.

Cov cuab yeej pabcuam hauv cov chaw tsim hluav taws xob nuclear: Qee cov khoom siv hauv cov chaw tsim hluav taws xob nuclear yuav tsum tau ua haujlwm nyob rau hauv qhov chaw qis qis. 16MnDR steel tuaj yeem siv los tsim cov plhaub, cov kav dej thiab lwm yam khoom siv ntawm cov cuab yeej no kom ntseeg tau tias muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov chaw tsim hluav taws xob nuclear thaum ua haujlwm.
