Piercing yog thawj kauj ruam ntawm kub dovseamless steel yeeb nkabdeformation, thiab nws lub luag hauj lwm yog kom cov khoom hollow raj billet hnav li capillary.Vim hnav lub capillary defects los yog eccentric (tsis sib npaug thickness) yog ib qho nyuaj rau tshem tawm los yog txo cov deformation txheej txheem, yog li ntawd, qhov zoo ntawm perforated capillary muaj ib tug tseem ceeb heev cuam tshuam rau qhov zoo ntawm kub dov seamless steel yeeb nkab.Txoj kev siab tube perforation xuas nrig ntaus, thawb lub teb piercing thiab tho.Thick-walled seamless steel mas siv nyob rau hauv roj av geology drilling yeeb nkab, petrochemical siv nyob rau hauv cracking hlab, boiler hlab, kav thiab tsheb bearings, tsheb laij teb, aviation thiab lwm yam precision raj qauv, nws cov txheej txheem raug: kub dov seamless steel raj puag ncig.→cua sov→peb perforated yob dov, dov los yog extrusion→cais tawm→sizing (los yog txo) cua txias→ncaj→hydrostatic test (los yog kuaj) logo→khaws cia.

Kub dov seamless steel ingot casting tuaj yeem rhuav tshem cov ntaub so ntswg, ua kom zoo ntawm cov hlau thiab tshem tawm cov teeb meem microstructure, kom cov hlau ntom cov ntaub so ntswg kho kom zoo dua qub.Qhov kev txhim kho no feem ntau yog tshwm sim nyob rau hauv cov kev taw qhia raws li dov kev taw qhia mus rau ib qho twg hauv cov hlau tsis yog isotropic lawm;pouring tsim npuas, tawg thiab xoob, tuaj yeem welded ntawm qhov kub thiab txias.

Tom qab kub dov seamless steel raj puag ncig ci mus rau lub siab puncher tho.Feem ntau ntau cov punch yog tapered menyuam xuas nrig ntaus tshuab, xuas nrig ntaus tshuab xws li kev ua haujlwm siab, khoom zoo, perforated expanding peev, tuaj yeem hnav ntau yam hlau.Tom qab perforation, round raj tau peb-yob dov, dov los yog extrusion.Txhawm rau nyem tawm cov yeeb nkab tom qab sizing.Sizing zeb rau hauv high-speed rotating cone laum los ntawm perforated steel embryo tsim steel.Cov yeeb nkab hauv txoj kab uas hla yog txiav txim los ntawm sab nraud txoj kab uas hla sizing zeb laum ntev.Tom qab sizing cov yeeb nkab mus rau hauv lub txias ntauwd los ntawm cov tshuaj tsuag txias yeeb nkab tom qab txias, nws yog tsim nyog yuav tsum tau ncaj.Tom qab straightening steel conveyor siv rau lub tshuab kuaj hlau (los yog kev ntsuas siab) rau kev kuaj sab hauv.Yog tias cov yeeb nkab sab hauv tawg, npuas thiab lwm yam teeb meem, yuav raug kuaj pom.Tom qab xaiv cov hlau tab sis kuj los ntawm kev tswj xyuas nruj heev.Tom qab cov hlau zoo, cov xim pleev xim rau ntawm tus lej, qhov loj me, batch tooj thiab lwm yam.Los ntawm ib tug crane mus rau hauv lub warehouse.
