Cov Khoom Siv Rau Cov Khoom Siv Hlau - ROYAL GROUP

1. Lub zog
Lub zog Performance index ntawm steel muaj elastic txwv, yield limit, thiab tensile txwv.Cov qauv tsim yog ua raws li lub zog tawm los ntawm cov hlau.High yield zog tuaj yeem txo qhov hnyav ntawm cov qauv, txuag steel thiab txo tus nqi.Lub zog tensile yog qhov siab tshaj plaws uas cov hlau tuaj yeem tiv taus ua ntej tsis ua haujlwm.Lub sijhawm no, cov qauv poob nws qhov kev ua tau zoo vim yog cov yas deformation, tab sis cov qauv deformation loj thiab tsis tawg, uas yuav tsum muaj peev xwm ua tau raws li qhov yuav tsum tau ua ntawm cov qauv ua haujlwm tsis tshua muaj av qeeg.
2. Plasticity
Lub plasticity ntawm steel feem ntau yog hais txog cov khoom ntawm cov yas tseem ceeb deformation yam tsis muaj kev puas tsuaj tom qab qhov kev ntxhov siab tshaj qhov taw tes tawm.Lub ntsiab Performance index ntsuas cov yas deformation muaj peev xwm ntawm steel yog elongation pob zeb thiab seem shrinkage u.
3. txias dabtsi yog khoov kev ua tau zoo
Cov cuab yeej 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 thiab txias.Cov cuab yeej khoov txias ntawm cov hlau yog txhawm rau kuaj cov cuab yeej khoov deformation ntawm cov hlau raws li kev qhia khoov los ntawm kev sim txias bending.
4. cuam tshuam toughness
Qhov cuam tshuam toughness ntawm steel yog hais txog lub peev xwm ntawm steel nyob rau hauv kev cuam tshuam load kom nqus txhua yam kinetic zog nyob rau hauv tus txheej txheem ntawm tawg.Nws yog cov cuab yeej cuab tam uas ntsuas cov txiaj ntsig ntawm cov hlau tsis kam rau kev cuam tshuam kev txiav thiab tuaj yeem ua rau tawg tawg vim qhov kub thiab txias thiab kev ntxhov siab.Feem ntau, qhov cuam tshuam toughness Performance index ntawm steel yog tau los ntawm kev ntsuam xyuas ntawm cov qauv qauv.
5. Kev ua haujlwm vuam
Lub vuam kev ua tau zoo ntawm cov hlau yog hais txog kev sib koom ua ke nrog kev ua haujlwm zoo tau txais los ntawm cov txheej txheem vuam tas li.Kev ua haujlwm vuam tuaj yeem muab faib ua ob hom: vuam kev ua haujlwm hauv cov txheej txheem vuam thiab vuam kev ua haujlwm hauv kev siv.Kev ua haujlwm vuam hauv cov txheej txheem vuam yog hais txog qhov rhiab heev ntawm qhov tsis muaj thermal tawg lossis txias shrinkage tawg hauv qhov vuam thiab cov hlau ze ntawm qhov vuam thaum lub sijhawm vuam.Kev ua haujlwm vuam zoo txhais tau hais tias tsis muaj qhov tawg ntawm cov hlau vuam thiab cov hlau nyob ze nyob rau hauv qee yam txheej txheem vuam.Lub vuam kev ua tau zoo nyob rau hauv cov nqe lus ntawm kev pab cuam kev ua tau zoo hais txog qhov cuam tshuam toughness ntawm vuam thiab ductility khoom nyob rau hauv lub tshav kub cuam tshuam cheeb tsam.Nws yuav tsum tau hais tias cov khoom siv ntawm cov hlau hauv qhov vuam thiab cov cua sov cuam tshuam tsis qis dua li ntawm cov khoom siv hauv paus.Peb lub teb chaws txais cov kev ntsuas kev ua tau zoo ntawm kev siv vuam hauv cov txheej txheem vuam, thiab tseem siv cov txheej txheem vuam kev ua tau zoo ntawm kev siv cov khoom.
6. Durability
Muaj ntau yam cuam tshuam rau kev ua haujlwm ntev ntawm cov hlau.Ua ntej tshaj plaws, kev tiv thaiv corrosion ntawm cov hlau tsis zoo, thiab kev tiv thaiv kev tiv thaiv yuav tsum tau coj los tiv thaiv steel corrosion thiab xeb.Kev tiv thaiv kev tiv thaiv yog: kev saib xyuas tsis tu ncua ntawm cov xim hlau, kev siv cov hlau galvanized, acid, alkali, ntsev thiab lwm yam muaj zog corrosive nruab nrab, kev siv cov kev tiv thaiv tshwj xeeb, xws li cov qauv offshore platform siv "anode tiv thaiv" ntsuas los tiv thaiv lub tsho. corrosion, tsau rau ntawm lub tsho zinc ingot, seawater electrolyte yuav cia li corrosion zinc ingot, thiaj li tiv thaiv kev ua haujlwm ntawm lub tsho steel.Qhov thib ob, vim hais tias cov hlau nyob rau hauv qhov kub thiab txias thiab lub sij hawm ntev load, nws tsis ua hauj lwm lub zog yog txo ntau tshaj lub sij hawm luv luv lub zog, yog li ntawd rau cov hlau nyob rau hauv lub sij hawm ntev kub kub ua hauj lwm, los txiav txim lub dag lub zog.Hlau hardens thiab ua nkig dhau sijhawm, ib qho tshwm sim hu ua kev laus.Qhov cuam tshuam toughness ntawm steel nyob rau hauv qis kub load yuav tsum tau kuaj.
