S275 welded kub- dov carbon steel round welded yeeb nkab yog ib hom yeeb nkab uas siv dav hauv kev tsim vaj tsev nyob rau hauv cov txheej txheem European. Nws zoo kawg nkaus ua ke cov khoom siv ntawm cov khoom siv, qhov tseeb ntawm kev tsim, thiab kev lag luam tus nqi, ua rau nws yog ib qho tseem ceeb ntawm cov tsev steel qauv niaj hnub.S275 welded kub-rolled carbon steel round welded yeeb nkab yog cov khoom siv pob txha rau niaj hnub steel qauv. Nrog nws cov qauv tsim muaj zog, kev ua haujlwm zoo heev, qhov tseeb geometric qhov ntev, thiab cov txiaj ntsig tseem ceeb ntawm kev lag luam, nws muab cov kws tsim qauv thiab cov kws tsim qauv tsim kev ntseeg siab rau kev ua tiav lub teeb yuag, loj - ncua, thiab ntau lub tsev tsim, ua rau nws yog qhov zoo tshaj plaws kev daws teeb meem kev nyab xeeb thiab kev ua haujlwm zoo.

Kub Rolling Txheej Taw Qhia rau S275 Round Carbon Steel Welded Pipes

Kub dov yog ib qho cuab yeej tseem ceeb rau dov hlau saum nws qhov kub ntawm recrystallization. Nws cov txheej txheem tseem ceeb yog raws li nram no:
1, Cua sov: Lub slab nruam txuas ntxiv yog muab tso rau hauv lub qhov cub cua sov thiab ua kom sov li ntawm 1200-1300 degree, austenitizing kub, muab nws zoo yas deformation peev xwm.
2, Rough Rolling: Tom qab descaling nrog siab - dej siab, lub liab - kub slab yog dov nyob rau hauv ntau yam dhau los ntawm ib tug reversible dov zeb, compressing lub thickness ntawm ob peb puas millimeters mus rau 30-50 millimeters.
3, Ua tiav Rolling: Lub nruab nrab slab yog ntxiv thinned rau lub hom phiaj thickness siv 6-7 sawv ntsug tas dov zeb, thiab lub phaj yog txias ntawm ib tug nruj tswj tus nqi siv ib tug laminar txaus txias system.
4, Coiling: Thaum lub strips txias rau kwv yees li 550-600 degree, nws yog coiled rau hauv ib lub coil los ntawm coiler, thaum kawg tsim cov khoom kub dov nrog cov qauv ntom ntom thiab cov khoom zoo heev.
