1.Dab tsi yog rebar
Lub npe nrov rau kub dov ribbed steel tuav yog rebar, tab sis vim li cas nws thiaj li hu ua rebar feem ntau vim tias lub npe no yog qhov tseeb thiab tiag tiag.
Qhov saum npoo ntawm threaded steel feem ntau muaj ob lub longitudinal tav thiab transverse ribs tusyees faib raws qhov ntev kev taw qhia.Nws muaj peb hom ntawm transverse tav: kauv, herringbone, thiab crescent.
2.Classification ntawm threaded steel
Kev faib tawm ntawm threaded steel sib txawv me ntsis ntawm cov teb chaws.Tuam Tshoj txais tus qauv GB1499.2-2018, uas faib cov xov hlau rau hauv peb theem raws li qib zog.
Rau hom rebar, lawv tuaj yeem muab faib ua: zoo tib yam kub dov steel tuav thiab nplua-grained kub dov steel tuav.Ordinary kub dov steel tuav: steel tuav xa hauv lub xeev kub dov, nws qib yog tsim los ntawm HRB, yield zog tus yam ntxwv tus nqi, thiab seismic cim (+ E)
Fine grained kub dov steel tuav: Zoo grained steel tuav tsim los ntawm kev tswj dov thiab tswj cov txheej txheem txias thaum lub sij hawm kub dov txheej txheem, nrog rau qib uas muaj HRBF, yield zog tus yam ntxwv qhov tseem ceeb, thiab seismic resistance cim (+E).H sawv cev rau kub dov, R sawv cev rau ribbed, thiab B sawv cev rau steel tuav
3.Production ntawm threaded steel
Screw xov hlau yog tsim los ntawm me me dov mills, uas yog muab faib ua nruam, semi nruam, thiab transverse hom.Feem ntau ntawm cov tshiab tsim thiab siv tag nrho txuas ntxiv me me dov mills hauv ntiaj teb.
