Kub tiav structural hollow seem ntawm non-alloy thiab nplua grain steels
Ntu 1: Cov txheej txheem xa khoom
Ntu 2: Tolerances, qhov ntev thiab cov khoom seem
Cold forming:
Cov txheej txheem ua tiav ntawm qhov kub thiab txias
Structrual hollow seem manufacturing txheej txheem:
Cov qauv hollow seem yog tsim los ntawm seamless los yog vuam.
Welded seem tsim los ntawm cov txheej txheem txuas ntxiv.
Hluav taws xob welded hollow seem yog muab tsis tau trimming lub internal weld hlaws.
Delivery conditon:
Zoo JR, J0, J2 thiab K2 - Kub tiav
Zoo N thiab NL - normalized. (normalized dov)
- rau kev ua kom txias txias ntxiv rau DC
- rau quenching thiab tempering ntxiv rau QT
Surface conditon:
Cov seem hollow muaj ib tug du nto sib haum mus rau txoj kev raug siv; pob, kab noj hniav los yog ntiav longitudinal grooves uas tshwm sim los ntawm cov txheej txheem raug tso cai, yog hais tias lub thickness yog nyob rau hauv kam rau ua.
