Txheej txheem txheej txheem thiab cov yam ntxwv ntawm steel qauv hla kab:
(1) Txheej txheem txheej txheem
Ob lub H-shaped steel kem yog tsim los ntawm kev txiav cov grooves ntawm ib nrab ntawm qhov ntev ntawm cov tswv cuab ntawm lub vev xaib steel kem, thiab tom qab ntawd vuam thiab kho ob lub H-shaped steels ntawm 90 degree rau ib leeg ntawm jig. ncej. Txoj kev no tuaj yeem tsis tsuas yog txo qhov ua haujlwm ntawm kev sib dhos, tab sis kuj txo qhov vuam deformation. Piv nrog rau cov txheej txheem tsim khoom, nws yooj yim dua hauv kev tsim khoom. Nyob rau tib lub sijhawm, rau cov tswvcuab hla nrog cov ntu me me uas tsis yooj yim rau kev khiav lag luam, nws yooj yim dua rau kev khiav lag luam nrog cov txheej txheem txheej txheem no.
(2) Txheej txheem yam ntxwv
Nws muaj feem xyuam rau kev tsim cov kab hla hla nrog lub web thickness Ntau dua lossis sib npaug ntawm 16 hli: txoj kev tsim khoom yog yooj yim thiab kev ua haujlwm yooj yim, uas tuaj yeem txo cov txheej txheem ntau lawm thiab ua kom luv luv ntawm lub voj voog ntawm lub tuam txhab steel qauv; qhov tseeb qhov seem yog ib qho yooj yim los xyuas kom meej; qhov vuam deformation yog yooj yim los tswj.
