Lub rooj cob qhia steel feem ntau yog hais txog tias cov khoom tseem ceeb ntawm cov kabmob yog tsim los ntawm cov hlau.Xws li cov ncej steel, steel beams, steel qauv foundations, steel ru tsev trusses (ntawm chav kawm, qhov ncua sij hawm ntawm lub Hoobkas lub tsev yog qhov loj, lub hauv paus steel qauv ru tsev trusses), steel ru tsev, nco ntsoov tias steel qauv phab ntsa tuaj yeem tswj tau los ntawm cov phab ntsa cib. .

Vim tias qhov nce hauv steel ntau lawm hauv kuv lub teb chaws, ntau lub rooj cob qhia steel qauv tau pib siv.Tshwj xeeb, nws tuaj yeem muab faib ua lub teeb thiab hnyav steel qauv kev cob qhia.Piv nrog rau cov qauv ntawm lwm cov ntaub ntawv, steel qauv muaj cov yam ntxwv hauv qab no:

Siab zog thiab lub teeb yuag.Txawm hais tias qhov ntom ntawm cov hlau yog siab dua li lwm cov khoom siv hauv tsev, nws lub zog yog siab heev.Nyob rau hauv tib txoj kev ntxhov siab, cov qauv hlau muaj qhov hnyav me me thiab tuaj yeem ua rau hauv cov qauv nrog qhov loj dua.

Lub plasticity ntawm cov hlau yog qhov zoo, thiab cov qauv yuav tsis tawg tam sim ntawd vim yog kev sib tsoo los yog ib nrab overload nyob rau hauv ib txwm muaj xwm txheej.Lub toughness ntawm steel ua rau cov qauv hloov mus rau dynamic loads.

kev ntseeg tau

Cov txheej txheem sab hauv ntawm cov hlau tsis sib xws thiab isotropic.Kev ua haujlwm tiag tiag ntawm kev ua haujlwmsteel qauvyog nyob rau hauv kev pom zoo nrog cov theoretical xam cov txiaj ntsig tau siv, yog li kev ntseeg siab ntawm cov qauv yog siab.

Solderability

Vim lub weldability ntawm steel, kev sib txuas ntawm steel qauv yog yooj yim heev, thiab nws yog haum rau tsim ntau yam complex-shaped lug.

High degree ntawm industrialization nyob rau hauv steel qauv tsim thiab installation

Kev tsim cov txheej txheem steel feem ntau yog nqa tawm hauv cov chaw tsim khoom tshwj xeeb hlau, yog li kev tsim khoom yooj yim thiab raug.Cov khoom tiav raug thauj mus rau qhov chaw rau kev teeb tsa, nrog rau qib siab ntawm kev sib dhos, kev teeb tsa nrawm nrawm thiab siv sijhawm luv.

Kev nruj

Cov qauv sab hauv ntawm cov hlau yog tuab heev, thiab thaum nws txuas nrog vuam, txawm tias thaum txuas los ntawm rivets lossis bolts, nws yooj yim ua kom nruj thiab tsis muaj qhov to.

Hluav taws kub tsis kam

Thaum qhov kub thiab txias ntawm cov hlau tsis pub dhau 150 ° C, lub zog ntawm cov hlau hloov me ntsis, yog li cov qauv hlau tsim nyog rau kev cob qhia kub.Thaum qhov kub siab tshaj 150 ° C, nws lub zog txo qis heev.Thaum qhov kub nce mus txog 500-600t, qhov kev siv yuav luag xoom.Yog li ntawd, nyob rau hauv qhov xwm txheej ntawm hluav taws kub, cov qauv steel muaj lub sij hawm luv luv ntawm hluav taws kub thiab yuav tshwm sim sai sai.Rau cov qauv steel nrog cov kev cai tshwj xeeb.Siv cov kev ntsuas kub rwb thaiv tsev thiab hluav taws kub.

Corrosion kuj

Hlau yog nquag xeb nyob rau hauv ib qho chaw ntub dej, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj corrosive xov xwm, thiab yuav tsum tau tu tsis tu ncua, uas yuav ua rau kom cov nqi tu.
