Cov txheej txheem ntau lawm ntawm txoj kab ncaj nraim welded yeeb nkab yog qhov yooj yim, qhov kev ua tau zoo yog siab, tus nqi qis, thiab kev loj hlob sai. Lub zog ntawm kauv welded kav feem ntau yog siab tshaj qhov ncaj seam welded kav. Welded kav nrog loj diameters yuav ua tau los ntawm cov nqaim billets, thiab welded kav nrog txawv diameters kuj yuav ua tau los ntawm billets ntawm tib lub dav. Txawm li cas los xij, piv nrog cov kav hlau ncaj ncaj ntawm tib qhov ntev, qhov ntev ntawm qhov vuam yog nce los ntawm 30 ~ 100%, thiab cov khoom ceev yog qis dua. Loj txoj kab uas hla los yog tuab welded kav feem ntau yog ua los ntawm steel blanks, thaum me me welded kav thiab nyias-walled welded kav tsuas yog yuav tsum tau ncaj qha welded los ntawm steel strips. Tom qab ntawd tsuas yog txhuam thiab txhuam nws.
Welded yeeb nkab txheej txheem ntws
Raw khoom uncoiling - flattening - kawg shearing thiab vuam - looper - sib sau - vuam - sab hauv thiab sab nraud weld hlaws tshem tawm - pre-correction - induction tshav kub kho - sizing thiab straightening - eddy tam sim no kuaj - txiav tawm - hydraulic tshuaj xyuas - pickling - zaum kawg tshuaj xyuas (Strictly tswj)-packaging-shipping.
