Cov txheej txheem ntau lawm ntawm seamless steel kav yuav muab faib ua txias txias thiab kub dov. Cov txheej txheem ntawm cov kav dej txias-dov seamless steel feem ntau nyuaj dua li kub dov. Lub raj khoob yuav tsum xub raug rau peb-yob txuas ntxiv dov, thiab tom qab ntawd qhov ntsuas qhov ntsuas yuav tsum tau ua tom qab extrusion. Yog tias tsis muaj cov lus teb tawg rau ntawm qhov chaw, lub raj puag ncig yuav tsum tau txiav los ntawm lub tshuab txiav thiab txiav mus rau hauv ib daim ntawv uas ntev li ib 'meter'. Tom qab ntawd nkag mus rau cov txheej txheem annealing. Annealing yuav tsum tau pickled nrog ib tug acidic kua. Thaum lub sij hawm pickling, xyuam xim rau seb puas muaj cov npuas loj ntawm qhov chaw. Yog tias muaj npuas ntau, nws txhais tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis ua raws li cov qauv sib xws. Nyob rau hauv tsos, lub txias-dov seamless steel yeeb nkab yog luv dua li kub dov seamless steel yeeb nkab. Cov phab ntsa tuab ntawm cov yeeb nkab txias-dov seamless steel feem ntau me dua li ntawm cov yeeb nkab kub-dov seamless steel yeeb nkab, tab sis qhov saum npoo zoo li ci dua li cov yeeb nkab tuab-walled seamless steel yeeb nkab, qhov saum npoo tsis dhau rough, thiab txoj kab uas hla. tsis muaj ntau burrs. Vim tsis muaj vuam, tsis muaj vuam.
