1. Q: Dab tsi yog qhov kev siv tseem ceeb ntawm SA210 qib steel kav hauv lub boiler system?
A:SA210 cov kav dej feem ntau yog siv hauv cov dej- cov phab ntsa vaj huam sib luag, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob ntawm cov tshuab boiler uas qhov kev pabcuam kub feem ntau qis dua 450℃-2-4. Lawv tau tsim los tiv taus siab sab hauv thiab ua kom yooj yim hloov cov cua sov.
2. Q: Dab tsi yog qhov tseem ceeb microstructural yam ntxwv ntawm SA210 steel, thiab vim li cas nws tseem ceeb?
A:Tus qauv microstructure ntawm SA210 steel muajferrite thiab pearlite-2-4. Cov qauv no muab qhov sib npaug zoo ntawm lub zog thiab ductility. Kev tuav lub cev tsis sib xws, nplua-grained version ntawm microstructure no yog qhov tseem ceeb rau kev nkag mus ntev thiab tiv thaiv kev ua tsis tiav ntxov.
3. Q: Dab tsi yog "banding" hauv SA210C steel, thiab nws tuaj yeem ua rau muaj teeb meem dab tsi?
A:Banding yog qhov tsis xws luag hauv microscopic qhov twg ferrite thiab pearlite theem ua ke nyob rau hauv alternating, elongated bands raws li dov kev taw qhia ntawm steel-1. Qhov no tsimanisotropy, txo cov khoom sib xws, plasticity, thiab toughness nyob rau hauv qee cov lus qhia, uas tuaj yeem ua rau muaj kev ntxhov siab-1.
4. Q: Yuav ua li cas yog qhov℃ntawm banding quantitatively soj ntsuam raws li ASTM cov qauv?
A:Ib txoj hauv kev meej yog txhais hauvASTM E 1268 Cov. Nws suav nrog kev tso ib daim phiaj hla micrograph thiab suav cov kev sib tshuam lossis cuam tshuam cov kab sib txuas ua ke nrog cov yam ntxwv microstructural (xws li pearlite) nyob rau hauv cov lus qhia sib npaug thiab perpendicular rau banding-1. IbAnisotropy Index (AI)yog xam los ntawm cov suav no los muab ib qho kev ntsuas ntau, rov qab ntsuas ntawm banding hnyav, txo tib neeg kev ua yuam kev hauv ciam teb kis-1-8.
5. Q: Yuav ua li cas yog tus qauv Suav teb (GB/T 13299) txoj kev ntsuam xyuas banding piv rau ASTM E1268?
A:GB / T 13299 txoj kev yog feem ntauzoo, cia siab rau qhov pom kev sib piv ntawm cov qauv rau cov qauv siv cov duab-1-8. Txoj kev no yooj yim dua tab sis muaj cov ntsiab lus siab dua thiab kev hloov pauv, tshwj xeeb tshaj yog rau kev ntsuas ciam teb. Thaum muaj kev tsis sib haum xeeb, lubQhov ntau thiab tsawg ASTM E1268 txoj kev raug pom zoo rau kev kuaj xyuasvim nws qhov tseeb dua-1.
