💡 Cov ntsiab lus tseem ceeb kom nkag siab
Lub ntsiab lus ntawm "Qib A": Hauv GB / T 700-2006 tus qauv, cov ntawv A, B, C, thiab D raws li Q235 sawv cev txawvqib zoo. Lawv feem ntau qhia txog kev nruj me ntsis hauv kev tswj cov teeb meem xws li sulfur thiab phosphorus, thiab seb puas muaj kev cuam tshuam toughness yog lav [citation: 1, citation: 4, citation: 6].
Qib A: Uatsis yoglav cuam tshuam toughness. Nws yog qib qis tshaj plaws uas yuav tsum tau nruj me ntsis. Yog li ntawd, nws yog qhov zoo - haum raucov qauv dav dav thiab qis - cov kua xa tawm siabqhov twg siab toughness tsis yog thawj qhov kev txhawj xeeb [citation: 1, citation: 4, citation: 6].
Daim ntawv ceeb toom hloov tshiab Standard: Tus qauv GB/T 700-2006 tau raug hloov los ntawmGB/T 700-2019"Carbon Structural Steels" [citation: 4, citation: 5]. Txawm hais tias xyoo 2006 yog tseem siv dav hauv kev lag luam, nws raug nquahu kom qhia meej lub xyoo tshwj xeeb ntawm tus qauv xav tau thaum nug lossis cog lus kom tsis txhob muaj kev nkag siab yuam kev. Cov kav dej tam sim no tsim kom tau raws li "GB/T 700-2006 Qib A" cov lus qhia yuav zoo li yog tsim los ntawm cov ntaub ntawv uas tseem ua raws li tus qauv tshiab 2019.
Hauv cov ntsiab lus,GB/T 700-2006 Qib A LSAW yeeb nkabyog ib qho kev txhim khu kev qha thiab tus nqi- cov khoom siv tau zoo, tsim los siv Q235A steel thiab qib siab - zoo submerged arc vuam txheej txheem los tsim loj - txoj kab uas hla longitudinal kav. Nws yog qhov kev xaiv zoo rau ntau lub hauv paus thiab kev tsim vaj tsev dav dav [citation: 1, citation: 3, citation: 6].
