Lub raj plaub yog ib hom qis-alloy high-strength steel qauv, uas siv tus qauv tshiab GB / T 1591-2018, qhov "Q" qhia lub zog tawm los thiab 355 qhia tias lub zog ntawm cov hlau yog 355MPa. , thiab tus nqi tawm los yuav txo qis raws li qhov nce ntawm cov thickness ntawm cov khoom.
Kev tsim cov txheej txheem ntawm cov raj plaub feem ntau yog siv cov txheej txheem dov thiab vuam. Tom qab cov txheej txheem dov, cov hlau tuaj yeem tau txais lub zog siab. Cov phaj hlau yog tom qab ntawd raug rau kev kho cua sov thiab cov txheej txheem vuam los tsim ib lub raj raj. Nyob rau hauv cov txheej txheem ntau lawm, nws yog ib qho tsim nyog yuav tsum tau ua raws li nruj raws li lub teb chaws cov qauv los xyuas kom meej qhov zoo thiab kev ua tau zoo ntawm steel kav.
Rectangular raj muaj ntau qhov zoo. Ua ntej ntawm tag nrho cov, nws yog heev corrosion resistant thiab yuav siv tau nyob rau hauv hnyav ib puag ncig. Qhov thib ob, nws muaj zog heev, muaj peev xwm tiv taus txhua yam kev hnyav, thiab muaj kev poob siab zoo. Tsis tas li ntawd, nws muaj vuam yooj yim, txias stamping, machinability, thiab kev ua haujlwm zoo, thiab tuaj yeem txiav thiab ua tiav ntau txoj hauv kev kom tau raws li qhov xav tau sib txawv.
Rectangular raj yog siv nyob rau hauv engineering tsim, iav kab hlau rhuav phab ntsa, qhov rooj thiab qhov rais kho kom zoo nkauj, steel qauv, guardrails, machinery manufacturing, tsheb tsim, khoom siv hauv tsev, shipbuilding, ntim, thiab lwm yam.
