Vuam H-beam steel thiab kub dov H-beam steel sib piv, nws cov yam ntxwv:
1. Ntau yam kev qhia tshwj xeeb (section loj). Qhov siab, lub vev xaib, flange thickness, flange dav tuaj yeem xaiv raws li tus neeg yuav tsum tau ua kom haum rau steel phaj vuam. Yuav siv tau rau kub-dov H-zoo li tus hlau sab nraum tus qauv ntau yam.
2, xaiv ntau yam hlau. Kub dov H-beams feem ntau yog Q235B thiab Q345B, thiab thaum cov khoom me me ntawm cov hlau tshwj xeeb xav tau, cov khoom cog tsis tuaj yeem tsim. Vuam tuaj yeem xaiv raws li qhov xav tau ntawm cov phaj steel.
3, siab precision, zoo nto zoo. Vim yog qhov siab precision thiab zoo nto zoo ntawm cov khoom siv hlau phaj, H qhov tseeb tom qab vuam kuj yog siab thiab qhov zoo ntawm qhov chaw zoo. Lub thickness sib txawv ntawm cov hlau phaj (siv rau vuam H-beam steel) feem ntau yog ob peb kaum ntawm ib millimeter mus rau ob peb kaum ntawm ib millimeter, thiab lub thickness sib txawv ntawm kub dov H-beam steel yog ob peb feem kaum ntawm ib. millimeter mus rau 1 millimeter, qhov txawv yog ze li ntawm 10 npaug.
4, kev ua haujlwm ruaj khov, lub koom haum zoo sab hauv. Txij li thaum los ntawm smelting mus nruam nruam mus rau dov, steel phaj ntau lawm yog siab tshaj cov txheej txheem yuav tsum, cov cuab yeej muaj peev xwm, tswj theem thiab nrhiav kom tau cov kub dov H-beam steel, lub koom haum sab hauv, tshuaj muaj pes tsawg leeg thiab ntau yam khoom (mechanical zog, txheej txheem zog. , thiab lwm yam) ntawm welded H-beam steel yog txhim khu kev qha thiab ruaj khov.
5, yooj yim rau muaj nyob vuam tsis xws luag. Txawm hais tias muaj ntau yam zoo saum toj no, vim yog vuam txoj kev, muaj vuam seem thermal stress nyob rau hauv vuam cheeb tsam, thiab lub koom haum ntawm vuam cheeb tsam yog txawv, muaj cov koom haum kev nyuaj siab, thiab nws yog ib qho yooj yim los tsim vuam tsis xws luag. Nrog kev txhim kho txuas ntxiv ntawm qib vuam thiab qib kev kho cua sov, cov kev tsis zoo no tau maj mam txo.
