TXHEEJ TXHEEM TXOG KEV TSIM KHOOM
Cov txheej txheem tsim khoom rau tus qauvH-beamsfeem ntau suav nrog cov kauj ruam tseem ceeb hauv qab no:
Kev Npaj Khoom Siv Raw: Cov khoom siv raw rau H-beams feem ntau yog cov hlau billets. Cov billets no raug ntxuav thiab cua sov kom npaj rau kev ua thiab tsim tom qab.
Kub Dov: Cov billets preheated raug pub rau hauv lub tshuab dov kub. Hauv lub tshuab dov kub, cov billets raug dov los ntawm ntau lub rollers, maj mam tsim cov duab hla ntawmH-beam.
Ua Haujlwm Txias (Xaiv Tau): Qee zaum, txhawm rau txhim kho qhov tseeb thiab qhov zoo ntawm H-beam, cov H-beams kub-kuav kuj tseem yuav raug ua haujlwm txias, xws li dov txias thiab kos duab.
Kev Txiav thiab Kev Ua Tiav: Tom qab dov thiab ua haujlwm txias, cov H-beams raug txiav thiab ua tiav kom tau raws li qhov loj me thiab qhov ntev tshwj xeeb raws li tus neeg siv khoom xav tau.
Kev Kho Mob Nto: Cov H-beams raug ntxuav thiab kho nrog kev tiv thaiv xeb kom ntseeg tau tias qhov zoo ntawm qhov chaw thiab kev tiv thaiv corrosion.
Kev Tshuaj Xyuas thiab Ntim Khoom: Cov H-beams uas ua tiav lawm yuav raug tshuaj xyuas zoo, suav nrog kev tshuaj xyuas seb puas zoo li cas, qhov loj me, thiab cov khoom siv kho tshuab. Thaum twg ua tau raws li qhov yuav tsum tau ua, lawv yuav raug ntim thiab xa mus rau tus neeg siv khoom.
