1. Cov txheej txheem ntawm cov kav dej seamless steel tuaj yeem muab faib ua ob hom: kev kos duab txias thiab kub dov. Cov txheej txheem ntawm cov kav dej txias-dov seamless steel feem ntau nyuaj dua li kub dov. Lub raj blanks yuav tsum xub raug rau peb-yob nruam dov, thiab ces extruded. Tom qab qhov ntsuas qhov ntsuas, yog tias tsis muaj cov lus teb tawg rau ntawm qhov chaw, cov yeeb nkab puag ncig yuav raug txiav los ntawm lub tshuab txiav thiab txiav rau hauv qhov khoob ntawm qhov ntev li ib 'meter'.
2. Nkag mus rau txheej txheem annealing. Annealing yuav tsum tau pickling nrog acidic kua. Thaum pickling, ua tib zoo saib seb puas muaj cov npuas loj ntawm qhov chaw. Yog tias muaj ntau qhov bubbling, nws txhais tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis tuaj yeem ua tau raws li cov qauv sib xws.
3. Lub xeev tus me nyuam ntawm kub dov seamless steel kav yog feem ntau nyob rau hauv lub kub dov lub xeev tom qab kev kho cua sov. Tom qab dhau qhov kev tshuaj ntsuam xyuas zoo, cov yeeb nkab kub-dov seamless steel yeeb nkab yuav tsum tau ua raws li kev tswj xyuas nruj nruj los ntawm cov neeg ua haujlwm. Tom qab kev soj ntsuam zoo, qhov saum npoo yuav tsum tau oiled, ua raws li los ntawm ntau qhov kev sim ua kom txias txias. Tom qab kev kho kub dov, ib qho kev sim perforation yuav tsum tau ua. , yog hais tias txoj kab uas hla ntawm lub perforation yog loj heev, nws yuav tsum tau straightened thiab kho.
