Cov txheej txheem ua cov hlau H-beam yog dab tsi?

Thaum nws los txog rau cov txheej txheem ua cov hlau H seem, muaj ntau txoj hauv kev siv ntau los tsim cov hlau zoo H beam. Cov txheej txheem no yog qhov tseem ceeb rau kev ua kom cov hlau carbon h beam ua tau raws li cov lus qhia thiab cov qauv uas xav tau rau kev tsim kho thiab kev siv hauv kev lag luam.
Ib qho ntawm cov thev naus laus zis tseem ceeb rau cov hlau kub dov H-beams yog dov kub. Cov hlau kub dov H-sections yog tsim los ntawm kev ua kom sov ib daim hlau billet kom txog thaum nws mus txog lub xeev ductile thiab tom qab ntawd dhau los ntawm ntau lub yob kom tsim cov duab H xav tau. Cov txheej txheem no tuaj yeem tsim150 * 150 hli H beam hlaunrog qhov ntev meej thiab kev ua haujlwm zoo heev.
Ntxiv rau kev dov kub, galvanizing yog lwm yam thev naus laus zis tseem ceeb rau H-puab hlau beam. Galvanized H-beam steel kem yog coated nrog ib txheej ntawm zinc los tiv thaiv cov hlau los ntawm corrosion, ua rau lawv zoo tagnrho rau sab nraum zoov thiab kev lag luam daim ntawv thov qhov twg raug rau cov ntsiab lus yog qhov yuav tsum tau xav txog. Cov txheej txheem no ua rau kom muaj zog thiab kev pabcuam lub neej ntawm cov hlau H-beams, kom ntseeg tau tias lawv tuaj yeem tiv taus cov xwm txheej ib puag ncig hnyav.
Tsis tas li ntawd xwb, kev siv cov hlau kub zoo H-sections, tshwj xeeb tshaj yogQ235B hlau H-beamua pov thawj txog cov thev naus laus zis ua haujlwm zoo siv hauv lawv cov khoom tsim tawm. Cov hlau H-zoo li no yog tsim los ntawm kev siv cov thev naus laus zis siab heev thiab kev tswj hwm zoo nruj kom ntseeg tau tias lawv ua tau raws li cov qauv kev lag luam siab tshaj plaws.
Cov chaw tsim khoom hlau H beam hauv Suav teb paub txog lawv txoj kev txawj ntse hauv kev ua cov qauv H-beam siv cov thev naus laus zis niaj hnub. Lawv txoj kev cog lus rau kev tsim kho kom raug thiab kev ruaj ntseg zoo tau ua rau lawv yog qhov chaw ntseeg siab rau ntau yam khoom H-beam kom tau raws li kev tsim kho thiab kev xav tau ntawm kev lag luam sib txawv.

Hauv ntej, cov txheej txheem ua cov hlau seem (tshwj xeeb tshaj yog H-section steel) ua lub luag haujlwm tseem ceeb hauv kev muab cov khoom zoo thiab kev ua tau zoo. Txawm hais tias nws yog cov hlau kub dov H-beams,Cov ncej galvanized hlau H beam, lossis cov hlau kub dov H beam, kev siv cov txheej txheem ua tiav siab heev ua kom ntseeg tau tias cov khoom siv hlau no ua tau raws li cov qauv siab tshaj plaws ntawm kev ruaj khov, lub zog thiab kev ntseeg tau.
