Dab tsi ntawm cov tsheb ciav hlau gnee cov tsheb ciav hlau
Kev Rail xub pwg yog semi-}}}}}}}} · embedded part los txhim kho cov phaj av clip, muaj ob hom kev tsheb ciav hlau yuav muaj los ntawmGnee, Nrum -} hauv lub xub pwgthiabWeld -}} ntawm lub xub pwg, ob qho tib si ntawm uas siv rau kev txhim kho ntawm kev sib tw ntawm kev vail clip. Ib qho yog ib leeg qia ntoo xub pwg siv hauv pre- txhawj xeeb qhob thiab lwm yam yog bi} block lossis ntxaib thaiv qhob ties.
Nrum - hauv kev tsheb nqaj hlau
Lub xub pwg sib xyaw ua lub ntsej muag txuas ntawm txoj kev tsheb nqaj hlau yog nias hauv cov chaw pw hauv tsev thiab ua haujlwm ua ke nrog cov clip kom nrawm nrawm. Qhov cam khwb cia hauv xub pwg yog ua los ntawm casting los ntawm cov cam khwb cia los ntawm cov hlau, xws li, GIS G5502 (xyoo 16293 (1985) lossis BS EN 1563 (1997).

Weld -} ntawm Rail sab xub pwg
Lub weld -}}}}}}}}}} On xub pwg yog siv txoj haujlwm ntawm cov ciav hlau yog weld ntawm tiaj tus hlau phaj ntau dua li cov qauv khi. Lub weld -}} hauv lub xub pwg ntau lawm las, nws yog fab forging rau cheeb tsam tus qauv. Cov khoom siv hlau khoom siv rau weld -}}} ntawm lub xub pwg tuaj yeem yog cov hlau roj carbon lossis nruab nrab nrog koj cov kev cai tshwj xeeb.
Rau cov ntaub ntawv:Cov kev thaiv kev nrum hlau lub xub pwg tuaj yeem welded nyob ntev ntev rau cov neeg muag khoom ntev dua thiab cov chaw nyob uas yuav hloov mus rau qhov chaw ntsug qhov twg. Qhov kev tsheb nqaj hlau lub peev xwm yuav tsum welded nyob rau hauv qhov chaw tshwj xeeb li dictated los ntawm cov txheej txheem tsim, qhov no ua rau nws muaj txiaj ntsig zoo thiab raug nqi rau hauv qhov no.
