Longitudinal Submerged Arc Vuam (LSAW) Cov txheej txheem

Nrog rau qhov no hauv siab, cov ntawv thov tseem ceeb rau cov kav dej LSAW muaj xws li roj, roj, roj av, cua sov hauv nruab nrab, dej, dej phwj tuaj kho thiab lwm yam kev siv zoo sib xws.

Cov kav hlau yog cov kav ntev ntev, uas yog siv los thauj cov khoom ntawm ib qho mus rau lwm qhov. Lawv tsuas yog tsim los ntawm ob txoj kev tsim khoom sib txawv, uas ua rau cov kav dej welded lossis seamless kav. Hauv ob txoj kev tsim khoom, cov hlau nyoos yog thawj zaug cam khwb cia rau hauv daim ntawv pib uas yooj yim rau txheej txheem (slab, kub billet lossis ca steel). Cov yeeb nkab yog tsim los ntawm kev ncab cov hlau kub / daim hlau rau hauv cov yeeb nkab uas tsis muaj seamless los yog nias cov npoo ntawm lub tiaj tus steel strip ua ke thiab muab khi nrog ib lub vuam.

Thaum cov kev khiav hauj lwm yuav tsum tau siab phab ntsa thickness vim lub siab sab hauv los yog sab nraud pressures, LSAW (Longitudinal Submerged Arc Welded) kav yog feem ntau cov kev daws teeb meem.

LSAW cov kav dej muaj qhov ntev ntawm qhov loj dua ERW (Electric Resistance Welded), feem ntau yog los ntawm 16 ntiv tes (406 hli) txog 60 ntiv tes (1500 hli). Nws muaj kev tiv thaiv zoo rau kev kub siab thiab qis kub corrosion.

Hauv LSAW yeeb nkab mills, kev ua haujlwm yog ua los ntawm txias ua cov pa roj carbon steel phaj, thiab ntau yam khoom ntawm cov yeeb nkab prefabricated yog nyob ntawm qhov no.

Cov khoom ntawm LSAW steel yeeb nkab yog ib chav tsev nruab nrab lossis tuab phaj, uas yog dov rau hauv ib lub kauj hauv lub tshuab tsim, welded thiab nthuav dav hauv txoj kab uas hla los ntawm ob chav submerged arc vuam. Nws muaj ntau yam specifications thiab zoo toughness, ductility, uniformity, ceev, thiab lwm yam
