Kub dov (extrusion seamless steel yeeb nkab): round tube → cua sov → perforation → → peb-yob dov, dov los yog extrusion → detached → sizing (los yog txo) → txias → ​​straightening hydraulic test (orflaw) → tag → cia.

Rolling seamless raj ntawm raw cov ntaub ntawv yog ib puag ncig raj, raj embryos mus los ntawm ib tug txiav tshuab txiav qhov kev loj hlob ntawm lub degree ntawm kwv yees li 1 meter, thiab xa los ntawm conveyor siv rauv cua sov.Billet yog noj rau hauv lub qhov cub cua sov, qhov kub thiab txias yog li 1200 degrees Celsius.Roj rau hydrogen lossis acetylene.Lub qhov cub kub tswj yog qhov tseem ceeb rau hnav lub raj cua puag ncig, tom qab tso tawm lub siab puncher.uas feem ntau muaj ntau dua puncher tapered roller punch no punch, siab ntau lawm efficiency, khoom zoo, perforated expanding ntim, hnav ntau yam steels.Tom qab perforation, round raj tau peb-yob hla dov, dov los yog extrusion.Tom qab extrusion tawm yeeb nkab sizing.Sizing zeb los ntawm kev sib hloov ceev ntawm lub khob hliav qab rau hauv Billet punch los tsim cov yeeb nkab steel.Cov yeeb nkab steel sab hauv txoj kab uas hla yog txiav txim siab los ntawm qhov ntev ntawm sab nraud txoj kab uas hla ntawm sizing zeb laum.Tom qab sizing, cov yeeb nkab steel kom nkag mus rau hauv cov cua txias ntauwd los ntawm cov dej txau txias, cov yeeb nkab steel tom qab txias, nws yog ib qho tsim nyog yuav tsum tau ncaj.Xa los ntawm cov yeeb nkab conveyor los ntawm straightening lub tshuab kuaj hlau (los yog hydrostatic test) ua ib qho kev tsis haum.Cov yeeb nkab steel sab hauv cov teeb meem xws li tawg, npuas yuav raug kuaj pom.Kev soj ntsuam zoo ntawm cov yeeb nkab steel tab sis kuj los ntawm kev xaiv phau ntawv nruj.Cov yeeb nkab steel ntawm Kev Tswj Xyuas Zoo, Kev Tshuaj Xyuas, siv cov xim pleev xim rau ntawm tus lej, qhov loj me, ntau lawm batch.Los ntawm ib lub tsheb cable dai rau hauv lub warehouse.
