Seamless steel yeeb nkab ntau lawm txheej txheem

Cov txheej txheem ntau lawm ntawm cov kav dej seamless steel tuaj yeem muab faib ua ob hom: kev kos duab txias thiab kub dov. Cov txheej txheem tsim khoom ntawm cov kav dej txias-dov seamless steel feem ntau nyuaj dua li kub dov. Cov yeeb nkab dawb paug thawj zaug yuav tsum tau mus rau peb lub yob txuas ntxiv dov, thiab tom qab extrusion, nws yuav tsum tau mus kuaj kab. Yog tias tsis muaj cov lus teb tawg rau ntawm qhov chaw, cov yeeb nkab puag ncig yuav tsum tau txiav los ntawm lub tshuab txiav, txiav lub billet nrog qhov ntev ntawm ib meter. Tom qab ntawd nkag mus rau cov txheej txheem annealing, uas yuav tsum tau acidic kua rau pickling. Thaum lub sij hawm pickling, kev saib xyuas yuav tsum tau them rau seb puas muaj npuas ntau ntawm qhov chaw. Yog tias muaj npuas ntau, nws qhia tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis ua raws li cov qauv sib xws. Visually, txias-dov seamless steel kav yog luv dua li kub dov seamless steel kav. Cov phab ntsa tuab ntawm cov kav dej txias-dov seamless steel feem ntau me dua li cov kav dej kub-kuav los tiag seamless steel kav, tab sis qhov saum npoo zoo li ci dua li cov yeeb nkab tuab tuab seamless steel kav, nrog tsawg roughness ntawm qhov chaw thiab tsawg burrs ntawm txoj kab uas hla.
Kev xa khoom ntawm cov kav dej kub-dov seamless steel feem ntau yog tias lub xeev kub-dov yog xa tom qab kev kho cua sov. Tom qab kev soj ntsuam zoo, cov kav dej kub dov seamless steel yuav tsum tau ua raws li cov neeg ua haujlwm nruj heev. Tom qab kev soj ntsuam, qhov saum npoo yuav tsum tau coated nrog roj, ua raws li los ntawm ntau yam kev sim ntsuas txias. Tom qab kev kho kub dov, kev sim perforation yuav tsum tau ua. Yog hais tias lub perforation txoj kab uas hla loj heev, straightening thiab kho yuav tsum tau nqa tawm. Tom qab ncaj nraim, nws yog thauj los ntawm lub conveyor mus rau lub tshuab kuaj rau kev kuaj, thiab thaum kawg sau npe thiab tus qauv ua ntej muab tso rau hauv lub warehouse.
Round raj → Cua sov → Piercing → Peb yob oblique dov, nruam dov los yog extrusion → Tube tshem tawm → Sizing (los yog txo) → Txias → Straightening → Hydraulic siab test (los yog flaw detection) → Marking → Cia seamless steel kav yog tsim los ntawm tho. steel ingots los yog tube khoom blanks rau hauv capillary hlab, uas yog ces kub dov, txias dov los yog txias drawn. Cov kev qhia tshwj xeeb ntawm seamless steel kav yog qhia raws li txheej kab * phab ntsa thickness hauv millimeters.
