Dab tsi yog qhov yuav tsum tau ua rau qhov zoo ntawm submerged arc welded steel kav?
Muaj cov kev cai nruj rau cov tsos zoo ntawm submerged arc welded steel kav thaum kuaj xyuas kom muaj kev nyab xeeb ntawm cov kav dej. Sab hauv thiab sab nrauv ntawm cov yeeb nkab steel yuav tsum tsis pub muaj qhov pom kev tsis zoo xws li tawg, tawg, nti, dov thiab delamination, thiab cov teeb meem no yuav tsum raug tshem tawm tag nrho, thiab qhov kev tshem tawm qhov tob yuav tsum tsis pub tshaj qhov sib txawv ntawm cov phab ntsa nominal. thickness, thiab qhov tseeb phab ntsa thickness ntawm qhov chaw tu yuav tsum tsis txhob tsawg tshaj li qhov tsawg kawg nkaus tso cai los ntawm phab ntsa thickness. Tsis tas li ntawd, yuav tsum tsis txhob muaj qhov tob ntawm ntau tshaj 6.4mm ntawm qhov chaw ntawm cov yeeb nkab steel, thiab qhov ntev ntawm lub qhov dej yuav tsum tsis pub tshaj 0.5 npaug ntawm cov yeeb nkab txoj kab uas hla ntawm txhua qhov kev taw qhia. Qhov seem qhov siab ntawm qhov vuam yuav tsum ua kom tau raws li qhov yuav tsum tau ua, thiab qhov seem yuav tsum tau grinded los xyuas kom meej qhov sib xws thiab smoothness ntawm vuam. Misalignment, uas yog, radial misalignment ntawm ob sab ntawm lub vuam, yuav tsum tsis txhob ntau tshaj 0.35 npaug ntawm phab ntsa thickness thiab qhov siab tshaj plaws yuav tsum tsis pub tshaj 3.0mm; rau cov kav hlau uas muaj phab ntsa tuab ntawm 13.0mm lossis tsawg dua; Rau cov kav hlau uas muaj phab ntsa thickness ntau dua 13. Lub vuam nws tus kheej yuav tsum tsis muaj qhov tsis xws luag xws li tawg, tawg arcs, hlawv los ntawm thiab arc pits, thiab cov duab yuav tsum sib npaug thiab du nrog kev hloov pauv. Cov kev xav tau zoo li no ua kom muaj kev ntseeg siab ntawm submerged arc welded steel yeeb nkab hauv kev siv tswv yim thiab tiv thaiv kev pheej hmoo tshwm sim los ntawm qhov tsis xws luag.
