1.JIS G3466 yog dab tsi thiab hom steel kav nws npog?
JIS G3466 yog Japanese Industrial Standard uas qhia txog cov cai raucarbon steel square thiab rectangular hollow seem, feem ntau hu ua square thiab rectangular steel hlab. Nws npog ob qho tib si welded thiab seamless hom siv feem ntau rau kev tsim qauv hauv kev tsim kho, tshuab, thiab ntau yam kev lag luam-1.
2.Dab tsi yog cov ntawv thov rau cov yeeb nkab steel ua raws li JIS G3466?
Cov kav dej no tau siv dav hauv cov qauv siv uas xav tau kev sib xyaw ua ke ntawm lub zog thiab zoo nkauj lossis ua haujlwm geometry. Common siv muaj xws li:
Kev tsim vaj tsev:Raws li cov kab, kab teeb, thiab purlins hauv steel ncej rau cov tsev, factories, thiab warehouses.
Infrastructure:Rau guardrails, kos npe rau kev txhawb nqa, thiab cov khoom siv hauv cov choj-1.
Machinery thiab Frames:Hauv kev tsim cov tshuab hauv paus, kev tiv thaiv kev tiv thaiv, thiab cov khoom siv tuav cov khoom thav duab.
Architectural Applications:Rau niaj hnub architectural designs, handrails, thiab exhibition lug vim lawv huv si, ntse kab.
3.Dab tsi yog cov qib tseem ceeb ntawm cov hlau tau teev tseg hauv JIS G3466 thiab lawv txawv li cas?
Tus qauv feem ntau suav nrog ntau qib raws li lawv qhov tsawg kawg nkaus tawm los lub zog thiab tshuaj muaj pes tsawg leeg, xws liSTKR400 thiab STKR490. Tus lej qhia qhov tsawg kawg nkaus tawm lub zog hauv MPa (piv txwv li, 400 MPa). Cov qib siab dua -qib steels zoo li STKR490 muaj zog ntau dua, tso cai rau sib zog los yog ntau dua load-cov kabmob, thaum STKR400 yog qib sib txawv, ntau yam rau kev siv dav.
4.YIS G3466 cov kav dej piv rau cov qauv thoob ntiaj teb zoo li ASTM A500 lossis EN 10219 li cas?
Thaum tag nrho peb cov qauv suav nrog hollow structural seem (HSS), lawv pib los ntawm ntau thaj tsam (Nyiv, Asmeskas, thiab Europe) thiab muaj qhov sib txawv.ASTM A500 1yog qhov kev qhia tshwj xeeb hauv Asmeskas,TS EN 10219yog European tus qauv rau txias-tsim welded seem, thiabJIS G3466yog qhov tseem ceeb hauv Nyiv thiab Asian lag luam. Qhov sib txawv tseem ceeb nyob rau hauv cov qib steel, cov tshuaj muaj pes tsawg leeg txwv, thiab cov khoom siv tshwj xeeb (xws li, lub zog tawm los, lub zog tensile). Kev hloov pauv ncaj qha yuav tsum tau ua tib zoo txheeb xyuas cov cuab yeej sib npaug rau daim ntawv thov tshwj xeeb.
5.Dab tsi yog qhov tseem ceeb ntawm qhov kam rau ua tau teev tseg hauv JIS G3466?
Tus txheej txheem qhia meej meej rau qhov ntev ntawm sab nraud (dav thiab qhov siab ntawm square / duab plaub), phab ntsa thickness, thiab hla -sectional squareness. Piv txwv li, rau ntau daim ntawv thov kev tsim kho, ib qho sab nraud qhov ntev kam rau ua± 0.5 hliyog suav tias yog tus qauv rau kev ua kom haum thiab yooj yim ntawm fabrication-1. Tighter tolerances yuav tsum tau rau precision mechanical applications.
