Cov yeeb nkab hlau yog ib qho tseem ceeb hauv ntau yam lag luam thiab daim ntawv thov, muab kev txhawb nqa cov qauv, xa cov kua dej thiab pab txhawb kev thauj mus los zoo.
Tsab xov xwm no lub hom phiaj yog los muab kev saib tob txog qhov sib txawv tseem ceeb ntawm EN10219 thiab EN10210 cov kav hlau, tsom mus rau lawv qhov kev siv, cov tshuaj lom neeg muaj pes tsawg leeg, lub zog tso zis, lub zog tensile, cov khoom cuam tshuam, thiab lwm yam tseem ceeb.
Qhov sib txawv tseem ceeb ntawm EN10219 thiab EN10210 cov kav hlau, tsom mus rau lawv qhov kev siv, cov tshuaj lom neeg muaj pes tsawg leeg, lub zog tso zis, lub zog tensile, cov khoom cuam tshuam, thiab lwm yam tseem ceeb.
kev siv: EN10219 cov kav hlau feem ntau yog siv rau hauv cov qauv siv xws li kev tsim kho, kev tsim kho vaj tse thiab cov thav duab tsev. Ntawm qhov tod tes, EN10210 cov kav hlau siv dav hauv kev tsim cov seem hollow, uas yog siv rau hauv kev tsim kho tshuab, tsheb thiab ntau lwm yam haujlwm tsim kho.
Cov tshuaj lom neeg sib xyaw: Cov tshuaj lom neeg sib xyaw ntawm EN10219 thiab EN10210 cov kav hlau sib txawv, uas cuam tshuam ncaj qha rau lawv cov khoom siv kho tshuab. EN10219 cov kav dej feem ntau qis dua hauv cov pa roj carbon, sulfur thiab phosphorous dua li EN10210 cov kav dej. Txawm li cas los xij, cov tshuaj lom neeg sib xyaw ua ke yuav txawv nyob ntawm qib tshwj xeeb thiab cov chaw tsim khoom.
Lub Zog Tawm: Lub zog tawm yog qhov kev ntxhov siab uas cov khoom siv pib hloov pauv mus tas li. EN10219 cov kav hlau feem ntau qhia txog cov txiaj ntsig muaj zog ntau dua piv rau EN10210 cov kav hlau. Lub zog tawm ntawm EN10219 cov kav dej ua rau nws tsim nyog dua rau cov ntawv thov uas xav tau lub peev xwm nqa khoom ntau dua.
Lub zog tensile: Lub zog tensile yog qhov siab tshaj plaws uas cov khoom siv tuaj yeem ua tau ua ntej tawg lossis tawg. EN10210 cov kav hlau feem ntau ua rau pom cov nqi zog tensile siab dua piv rau EN10219 cov kav hlau. Lub zog tensile siab dua ntawm EN10210 cov kav dej yog qhov zoo dua qhov twg cov kav dej raug rau cov khoom hnyav tensile lossis compressions ntau dua.
Kev ua tau zoo ntawm kev cuam tshuam: Kev ua tau zoo ntawm cov yeeb nkab hlau yog qhov tseem ceeb heev, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj qhov kub qis thiab qhov chaw ib puag ncig hnyav. EN10210 yeeb nkab yog lub npe hu rau nws qhov kev cuam tshuam zoo dua piv rau EN10219 yeeb nkab. Yog li ntawd, EN10210 yeeb nkab feem ntau nyiam nyob rau hauv cov lag luam uas qhov kev tiv thaiv rau kev tawg yooj yim yog qhov tseem ceeb.
Lwm cov ntsiab lus:
a. Kev Tsim Khoom: Ob qho tib si EN10219 thiab EN10210 cov kav dej yog tsim los ntawm kev ua haujlwm kub lossis txias, nyob ntawm seb qhov yuav tsum tau ua tshwj xeeb.
b. Kev kam rau qhov ntev: EN10219 thiab EN10210 cov kav dej muaj qhov sib txawv me ntsis thiab qhov no yuav tsum tau txiav txim siab kom ntseeg tau tias haum thiab sib xws hauv ntau daim ntawv thov.
c. Qhov chaw tiav: Cov kav dej EN10219 thiab EN10210 yuav muaj qhov chaw tiav sib txawv nyob ntawm cov txheej txheem tsim khoom thiab cov kev xav tau npaj qhov chaw.
Xaus lus: EN10219 thiab EN10210 cov kav hlau muaj ntau yam kev siv hauv ntau yam kev lag luam. Kev nkag siab txog qhov sib txawv tseem ceeb hauv lawv lub hom phiaj, cov tshuaj lom neeg muaj pes tsawg leeg, lub zog tso zis, lub zog tensile, cov khoom cuam tshuam, thiab lwm yam tseem ceeb yog qhov tseem ceeb hauv kev xaiv cov kav hlau tsim nyog tshaj plaws rau ib qho project lossis daim ntawv thov tshwj xeeb. Txawm hais tias rau kev tsim cov qauv, cov seem hollow, lossis lwm yam kev siv engineering, kev nkag siab txog qhov sib txawv no yuav ua kom muaj kev ua tau zoo tshaj plaws thiab kev ntseeg siab ntawm cov kav hlau xaiv.
