Dab tsi yog qhov txawv ntawm EN10210 thiab EN10219
TS EN 10210thiabTS EN 10219yog ob qho tib si European qauv rau hollow seem siv nyob rau hauv cov qauv siv.
1. EN10210:kub tiav hollow seemTS EN 10219:txias tsim hollow seem
2.Hot tiav Hollow Section thiab Cold tiav Hollow Section:
Kub tiav hollow seem yog tsim los siv cov txheej txheem uas cov hlau tau rhuab mus rau qhov kub thiab txias thiab tom qab ntawd tsim rau hauv cov duab uas xav tau. Cov txheej txheem no ua rau cov khoom lag luam nrog lub ntsej muag smoother thiab nruj dua tolerances.
Txias tsim hollow seem yog tsim los ntawm txias ua cov ntawv hlau los yog sawb rau hauv cov duab uas xav tau, tsis muaj cua sov ntxiv.
3. Qhov ntau thiab tsawg thiab tolerances:
EN10210 qhia qhov ntau thiab tsawg thiab nruj dua li EN10219. Qhov no yog vim qhov kub tiav hollow seem yog tsim nrog cov txheej txheem kev tsim khoom ntau dua piv rau cov khoom txias tsim hollow.
Tsis tas li ntawd, cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab cov khoom siv kho tshuab kuj sib txawv ntawm ob tus qauv. Cov tshuaj muaj pes tsawg leeg ntawm EN10210 yog txwv ntau dua, thiab nws yuav tsum ua kom tau raws li qhov xav tau siab dua rau qee yam khoom xws li carbon, sulfur, thiab phosphorus. Cov khoom siv kho tshuab xws li lub zog tawm los, lub zog tensile, thiab elongation kuj tau teev sib txawv rau txhua tus qauv.
Hauv cov ntsiab lus, ob qho tib si EN10210 thiab EN10219 yog cov qauv European rau hollow seem siv hauv cov qauv siv, tab sis lawv txawv ntawm cov txheej txheem tsim khoom, qhov ntau thiab tsawg thiab kam rau ua, tshuaj muaj pes tsawg leeg, thiab cov khoom siv tshuab. Nws yog ib qho tseem ceeb uas yuav tau xaiv tus qauv tsim nyog raws li cov kev cai tshwj xeeb ntawm daim ntawv thov.
