1. Cov kev txwv lossis qhov tsis zoo ntawm cov yeeb nkab kub kub yog dab tsi?
Teb:Disadvantages muaj xws li:
Dimensional Tolerances:Tsawg dua qhov txias- cov khoom tiav.
Nto tiav:Rough thiab scaled nto, feem ntau yuav tsum tau ntxuav ntxiv (xws li, pickling, sandblasting) rau tej daim ntaub ntawv.
Residual Stress:Muaj peev xwm muaj kev ntxhov siab ntau dua sab hauv uas yuav ua rau muaj kev cuam tshuam yog tias machined.
2. Dab tsi tsis yog -kev kuaj kev puas tsuaj (NDT) txoj kev uas feem ntau siv los tshuaj xyuas cov yeeb nkab kub?
Teb:Cov txheej txheem NDT uas muaj xws li:
Kev kuaj ultrasonic (UT):Txhawm rau txheeb xyuas qhov flaws sab hauv thiab subsurface.
Eddy Current Testing (ET):Txhawm rau kuaj xyuas qhov chaw thiab ze rau - qhov chaw tsis xws luag, tshwj xeeb tshaj yog nyob rau hauv cov yeeb nkab seamless.
Kev Ntsuas Hydrostatic:Txhawm rau txheeb xyuas qhov siab ncaj ncees ntawm cov yeeb nkab los ntawm kev sau nws nrog dej ntawm qhov ntsuas qhov ntsuas siab.
Kev tshuaj xyuas qhov muag:Txhawm rau txheeb xyuas qhov tsis zoo ntawm qhov chaw thiab qhov xwm txheej.
3. Cov ntsiab lus carbon cuam tshuam li cas ntawm cov yeeb nkab kub dov?
Teb:Cov ntsiab lus carbon tseem cuam tshuam rau cov yeeb nkab cov khoom:
Cov pa roj carbon tsawg (<0.25%):Zoo ductility thiab weldability, siv rau cov qauv siv.
Cov pa roj carbon nruab nrab (0.25% - 0.60%):Lub zog siab dua, siv rau cov khoom siv tshuab thiab qee yam kev siv siab.
High Carbon (>0.60%):Lub zog siab heev tab sis tsis tshua muaj ductility thiab tsis zoo weldability, siv rau cov cuab yeej tshwj xeeb thiab cov khoom siv.
4. Vim li cas cov yeeb nkab kub dov feem ntau nyiam rau kev siv cov txheej txheem tshaj qhov txias dov?
Teb:It is preferred because its more ductile and less brittle nature makes it better at absorbing energy and withstanding dynamic loads, impacts, and seismic events, which are critical considerations in structural frameworks and construction.
5. Dab tsi yog qhov txawv ntawm "Kub Tiav" thiab "Kub Rolled" yeeb nkab?
Teb:Cov ntsiab lus feem ntau siv sib hloov, tab sis muaj qhov sib txawv me ntsis:
Kub Rolledfeem ntau yog hais txog thawj txheej txheem ntawm shaping cov hlau ntawm qhov kub thiab txias.
Kub Tiav lawmfeem ntau txhais tau hais tias qhov kawg sizing thiab shaping kuj tau ua tiav ntawm qhov kub thiab txias yam tsis muaj kev ua haujlwm txias. Hauv kev xyaum, rau cov kav dej, "kub tiav" feem ntau yog siv los piav txog cov kav dej seamless uas ua tiav kub, sib txawv ntawm cov kav dej txias -kos seamless kav.
