Cov Khoom Siv Uas Yuav Tsum Tau Siv Rau Cov Qauv Hlau - ROYAL GROUP

1. Lub zog
Cov ntsuas zog ntawm cov hlau muaj xws li elastic limit, yield limit, thiab tensile limit. Tus qauv tsim yog raws li lub zog yield ntawm cov hlau. Lub zog yield siab tuaj yeem txo qhov hnyav ntawm cov qauv, txuag hlau thiab txo tus nqi. Tensile strength yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej ua tsis tiav. Lub sijhawm no, cov qauv poob nws qhov kev ua tau zoo vim yog kev hloov pauv yas, tab sis qhov kev hloov pauv ntawm cov qauv loj thiab tsis tawg, uas yuav tsum muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm cov qauv tiv taus rau cov av qeeg tsawg.
2. Kev ua yas
Feem ntau, qhov plasticity ntawm cov hlau yog hais txog cov khoom ntawm cov yas deformation tseem ceeb yam tsis muaj kev tawg tom qab kev ntxhov siab tshaj qhov yield point. Lub ntsiab ntsuas los ntsuas qhov muaj peev xwm deformation ntawm cov hlau yog elongation pob zeb thiab seem shrinkage u.
3. kev ua haujlwm txias
Qhov khoom siv khoov txias ntawm cov hlau yog qhov ntsuas ntawm qhov tsis kam ntawm cov hlau kom tawg thaum cov yas deformation tshwm sim hauv cov txheej txheem khoov ntawm qhov kub ib txwm. Qhov khoom siv khoov txias ntawm cov hlau yog los sim qhov khoom siv khoov deformation ntawm cov hlau raws li qib khoov tshwj xeeb los ntawm kev sim khoov txias.
4. Kev cuam tshuam tawv
Qhov kev cuam tshuam ntawm cov hlau yog hais txog lub peev xwm ntawm cov hlau nyob rau hauv qhov kev cuam tshuam thauj khoom kom nqus tau lub zog kinetic thaum lub sijhawm tawg. Nws yog ib qho khoom siv kho tshuab uas ntsuas qhov cuam tshuam ntawm cov hlau tiv taus kev cuam tshuam thauj khoom txiav thiab tej zaum yuav ua rau tawg vim qhov kub qis thiab kev ntxhov siab. Feem ntau, qhov cuam tshuam toughness index ntawm cov hlau yog tau los ntawm kev sim cuam tshuam ntawm cov qauv txheem.
5. Kev ua haujlwm vuam
Kev ua tau zoo ntawm kev vuam hlau yog hais txog qhov sib koom ua ke uas muaj kev ua tau zoo nyob rau hauv cov txheej txheem vuam tas li. Kev ua tau zoo ntawm kev vuam muaj ob hom: kev ua tau zoo ntawm kev vuam hauv cov txheej txheem vuam thiab kev ua tau zoo ntawm kev vuam siv. Kev ua tau zoo ntawm kev vuam hauv cov txheej txheem vuam yog hais txog qhov rhiab heev ntawm tsis muaj qhov tawg thermal lossis qhov tawg txias hauv qhov vuam thiab cov hlau ze ntawm qhov vuam thaum lub sijhawm vuam. Kev ua tau zoo ntawm kev vuam txhais tau tias tsis muaj qhov tawg hauv cov hlau vuam thiab cov hlau hauv paus nyob ze nyob rau hauv qee qhov xwm txheej vuam. Kev ua tau zoo ntawm kev vuam hauv cov nqe lus ntawm kev ua haujlwm yog hais txog qhov cuam tshuam ntawm qhov vuam thiab cov khoom siv ductility hauv thaj chaw cuam tshuam kub. Nws yog qhov yuav tsum tau ua kom cov khoom siv kho tshuab ntawm cov hlau hauv qhov vuam thiab thaj chaw cuam tshuam kub tsis qis dua li cov khoom siv hauv paus. Peb lub tebchaws siv cov txheej txheem xeem kev ua tau zoo ntawm kev vuam hauv cov txheej txheem vuam, thiab kuj siv cov txheej txheem xeem kev ua tau zoo ntawm kev siv.
6. Kev ruaj khov
Muaj ntau yam uas cuam tshuam rau qhov ruaj khov ntawm cov hlau. Ua ntej tshaj plaws, cov hlau tsis kam tiv taus corrosion, thiab yuav tsum tau ua cov kev tiv thaiv kom tiv thaiv cov hlau xeb thiab xeb. Cov kev tiv thaiv yog: kev saib xyuas cov xim hlau tas li, kev siv cov hlau galvanized, kua qaub, alkali, ntsev thiab lwm yam kev kub ntxhov, kev siv cov kev tiv thaiv tshwj xeeb, xws li cov qauv platform offshore siv "anode tiv thaiv" kev ntsuas los tiv thaiv kev xeb ntawm lub tsho, kho rau ntawm lub tsho zinc ingot, dej hiav txwv electrolyte yuav cia li xeb zinc ingot, kom tiv thaiv kev ua haujlwm ntawm lub tsho hlau. Qhov thib ob, vim tias cov hlau nyob rau hauv qhov kub siab thiab lub nra hnyav ntev, nws lub zog tsis ua haujlwm raug txo qis ntau dua li lub zog luv luv, yog li rau cov hlau nyob rau hauv qhov kub siab ntev, txiav txim siab lub zog ntev. Hlau tawv thiab ua brittle dhau sijhawm, ib qho phenomenon hu ua laus. Yuav tsum tau sim qhov cuam tshuam ntawm cov hlau nyob rau hauv qhov kub qis.
