I. OVERVIEW NTAWM COV TXHEEJ TXHEEM
JIS G3466 yog kev lag luam Japanese yog ib qho xwmfab thiab duab plaub hau steel kav tsim los ntawm cov txheej txheem vuam lossis cov txheej txheem sib dhos. Txias-tsim xwmfab thiab duab plaub welded steel tubes rau cov qauv dav.

•Cov tau txais daim ntawv thov:Mas siv rau hauv cov qauv tsim tsev (xws li cov qauv hlau nplaum, choj, cov khoom siv hluav taws xob (cov cuab yeej siv hluav taws xob (tsheb ua liaj ua teb (cov tsheb ua liaj ua teb (cov tsheb ciav hlau), cov tsheb ciav hlau (cov tsheb ciav hlau
• Qhov tseeb version:Jis g 3466-2021, uas specifies cov kev xav tau ntawm cov kav hlau hlau hauv Civil thiab lub tsev hlau qauv.

Ii.Material thiab kev ua tau zoo
1. Cov Khoom Siv Uas Siv
• Carbon Steel: Q235, Q215, SS400, thiab lwm yam, kom tau raws li cov kev muaj zog dav dav.
• Cov Hlau Hlau Tsawg: Q345 (16mn), Q390, thiab lwm yam, rau cov xwm txheej xav tau lub zog lossis huab cua tsis taus.
• Lwm cov ntaub ntawv: qee qhov scenes siv cov hlau tsis muaj roj (xws li JIS G3459).

2. Kev ua txuj ci
• Cov qhov raug qhov tseeb: nruj me ntsis kev tiv thaiv ntev ntev ntawm ntu (xws li sab ntev, phab ntsa thickness kam tsis pub dhau ± 10%) kom ntseeg tau tias lub rooj sib txoos haum.
• Vuam kev ua yeeb yam: Lub Weld yuav tsum tau kuaj qhov tsis yog-kev tshuaj xyuas kev ua kom paub tseeb) kom ntseeg tau tias tsis muaj cov kab nrib pleb, pig thiab lwm yam tsis xws luag.
• Lub zog kho tshuab: tensile lub zog ntau dua los yog sib npaug rau 370 MPa, kom muaj nuj nqis rau 235 MPa (Q235 ua ib qho piv txwv), haum rau cov qauv thauj khoom.

III.Production
1. Txias kev tswj hwm thiab vuam
• Cov kauj ruam kauj ruam: cov hlau sawb tsis tau, tiaj tus, dov mus rau hauv lub voos xwmfab / duab dhos ua ke, thiab thaum kawg cov raj loj tiv thaiv (ERW) lossis arc vuam.
Hom Weld: Ncaj Seam Weld (ntau dua) lossis muab kauv weld.

2. Seamens cov txheej txheem
• Seamist cov plaub hau yog tsim los ntawm kub dov lossis cov txheej txheem txias rau kev siv siab, xws li kho tshuab hydraulic (xws li kho tshuab hydraulic).

3. Nto Kho
• Yeem Galvanizing (kub plating lossis electroplating), roj, pickling, thiab lwm yam, txhim kho corrosion tsis kam.

IV.Application teb
JIS G3466 yeeb nkab steel vim muaj lub zog siab thiab ua tiav yooj yim, siv dav hauv:
1. Kev tsim kho: Hlau qauv thav duab, ru tsev truss, cov ntaub thaiv hluav taws xob.
2. Mechanical Manufacturing: Tsheb Chassis Qhov Chaw, Kev Txhawb Nqa Tshuab, Hnub Ci Khoom Siv Hlaub.
3. Cov Tsheb Tsim Tsheb Tsim: Cov thawv pob txha pob txha, cov neeg tiv thaiv kev tsheb ciav hlau, kev txhawb nqa choj.
4. Lwm liaj teb: Agricultural tsev ntsuab, rooj tog kho kom zoo nkauj, nkoj sab hauv qauv.
