manufacturing txheej txheem ntawm railroad joint bars
Kev tsim cov txheej txheem ntawm kev tsheb ciav hlau sib koom ua ke muaj ob peb kauj ruam hauv qab no, cia peb pom lawv.
Forging:
Cov khoom siv raw (steel, cam khwb cia hlau, lossis malleable hlau) yog rhuab mus rau qhov kub thiab txias.
Siv rauj los yog xovxwm, cov khoom yog zoo li tus rau hauv daim ntawv xav tau.
Forging ua kom qhov ntom ntom, sib xws, thiab kev ywj pheej los ntawm qhov tsis xws luag hauv qhov sib koom ua ke.
Machining:
Lub forged joint bar undergos txiav thiab shaping kom ua tiav qhov ntev.
Machining xyuas kom meej qhov loj me, cov duab, thiab lub ntsej muag du tsis muaj qhov tsis zoo.
Kev kho cua sov:
Qhov tseem ceeb rau lub zog thiab durability.
Qhov sib koom ua ke yog rhuab mus rau qhov kub thiab txias sai sai.
Ua kom tawv tawv, muaj zog, thiab tsis kam hnav thiab tsim kua muag.
Ua tiav:
Ntxuav thiab polishing tshem tawm tej yam tsis zoo tag nrho.
Npaj qhov sib koom ua ke rau kev teeb tsa.
Cov txheej tiv thaiv tuaj yeem raug ntxiv los txhim kho kev tiv thaiv corrosion thiab hnav.
