Seamless steel yeeb nkab yog perforated los ntawm tag nrho cov hlau puag ncig, thiab cov yeeb nkab steel uas tsis muaj vuam ntawm qhov chaw hu ua seamless steel yeeb nkab. Raws li txoj kev tsim khoom, cov yeeb nkab seamless steel tuaj yeem muab faib ua kub dov seamless steel yeeb nkab, txias dov seamless steel yeeb nkab, txias-draw seamless steel yeeb nkab, extruded seamless steel yeeb nkab, yeeb nkab jacking thiab lwm yam. Raws li cov duab seem, seamless steel yeeb nkab tau muab faib ua ob hom: puag ncig thiab zoo li tus. Qhov siab tshaj plaws txoj kab uas hla yog 900 hli thiab qhov tsawg kawg nkaus txoj kab uas hla yog 4 hli. Raws li kev siv sib txawv, muaj cov phab ntsa tuab seamless steel kav thiab nyias phab ntsa seamless steel kav. Seamless steel yeeb nkab yog siv rau roj av geological drilling yeeb nkab, petrochemicalcev rv, boiler cev, bearing tub thiabhigh-precision structural steel yeeb nkabrau tsheb, tsheb laij teb thiab aviation. 

Raws li kev siv tau muab faib ua cov hom phiaj dav dav (rau cov dej, cov kav dej thiab cov khoom siv, cov khoom siv kho tshuab) thiab tshwj xeeb (rau boilers, geological tshawb nrhiav, bearings, acid resistance, etc.) ob pawg.

Lub hom phiaj dav dav seamless steel yeeb nkab yog dov los ntawm cov pa roj carbon zoo tib yam, cov hlau tsis tshua muaj hlau lossis cov hlau hlau alloy, thiab muaj cov khoom siv loj tshaj plaws, feem ntau yog siv los ua cov raj xa dej lossis cov txheej txheem rau kev xa cov kua dej. Muaj ntau ntau yam seamless kav rau lub hom phiaj tshwj xeeb, xws li boiler seamless kav, tshuaj fais fab kav, geological seamless kav thiab roj av seamless kav. Seamless steel yeeb nkab muaj qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob.

Seamless steel yeeb nkab ntau lawm txheej txheem:

① Cov txheej txheem tseem ceeb ntawm kub dov seamless steel yeeb nkab (△ Cov txheej txheem tshuaj xyuas tseem ceeb): 

Kev npaj thiab tshuaj xyuas △ → Cua sov → perforating → Rolling → reheating → Sizing → Thaum tshav kub kub kho △ → Ncaj → Tiav → Kev tshuaj xyuas △ (tsis muaj kev puas tsuaj, lub cev thiab tshuaj lom neeg, tshuaj xyuas lub rooj) → cia

② Txias dov (kos) seamless steel yeeb nkab txheej txheem ntau lawm:

Kev npaj dawb → pickling lubrication → Txias dov (kos duab) → Kev kho cua sov → straightening → tiav → tshuaj xyuas

Cov txheej txheem ntawm seamless steel yeeb nkab ntau lawm tuaj yeem muab faib ua ob hom kev kos duab txias thiab kub dov, txias dov seamless steel yeeb nkab txheej txheem yog feem ntau nyuaj tshaj li kub dov, lub raj billet ua ntej nqa tawm peb cov menyuam txuas ntxiv dov, extrusion tom qab sizing xeem. , yog tias qhov chaw tsis teb rau qhov tawg tom qab lub raj puag ncig yuav raug txiav los ntawm lub tshuab txiav, txiav qhov kev loj hlob ntawm ib meter dawb paug. Tom qab ntawd nkag mus rau hauv cov txheej txheem annealing, annealing nrog acidic kua pickling, pickling yuav tsum tau them sai sai rau seb puas muaj ntau cov npuas nyob rau ntawm qhov chaw, yog hais tias muaj ib tug loj tus naj npawb ntawm npuas, qhia tau hais tias qhov zoo ntawm cov yeeb nkab steel tsis tuaj yeem ua tau raws li qhov xav tau. cov qauv sib raug. Cov tsos ntawm txias dov seamless steel yeeb nkab yog luv dua li ntawm kub dov seamless steel yeeb nkab, phab ntsa thickness ntawm txias dov seamless steel yeeb nkab yog feem ntau me dua li ntawm kub dov seamless steel yeeb nkab, tab sis qhov saum npoo zoo li ci dua. uas tuab-walled seamless steel yeeb nkab, nto tsis dhau ntxhib, thiab lub caliber tsis dhau burr.

Kev xa tawm ntawm kub dov seamless steel yeeb nkab yog feem ntau xa tom qab kub dov kub kho. Kub dov seamless steel yeeb nkab tom qab kev soj ntsuam zoo mus los ntawm cov neeg ua hauj lwm nruj tswj kev xaiv, tom qab kev soj ntsuam zoo mus nqa tawm cov roj saum npoo, thiab ces ua raws li los ntawm ib tug xov tooj ntawm txias drawing xyaum, kub dov kev kho mob mus nqa tawm qhov kev xeem ntawm perforation. , yog hais tias lub perforation o loj heev yuav tsum straightener. Tom qab straightening, nws raug xa mus rau lub flaw detection tshuab los ntawm cov kis tau tus mob ntaus ntawv rau flaw detection sim, thiab thaum kawg sau npe, formatted thiab muab tso rau hauv lub warehouse.

Round raj → cua sov → perforation → peb-yob skew dov, nruam dov los yog extrusion → Stripping → sizing (los yog txo) → Txias → straightening → dej siab ntsuam xyuas (los yog soj ntsuam) → Marking → Seamless steel yeeb nkab nyob rau hauv cia yog ua los ntawm steel ingot los yog tube khoom dawb paug los ntawm perforation los ua capillary raj, thiab ces kub dov, txias dov los yog txias txias. Cov specifications ntawm seamless steel yeeb nkab yog qhia los ntawm lub sab nraud txoj kab uas hla * phab ntsa thickness ntawm millimeters.

Sab nraud txoj kab uas hla ntawm cov yeeb nkab kub-dov seamless feem ntau yog ntau dua 32 hli, phab ntsa tuab yog 2.5-200mm, sab nraud txoj kab uas hla ntawm cov yeeb nkab txias-dov seamless steel yeeb nkab tuaj yeem yog 6 hli, phab ntsa tuab tuaj yeem yog 0.25mm, sab nraud txoj kab uas hla. ntawm cov yeeb nkab nyias nyias tuaj yeem yog 5 hli, phab ntsa tuab yog tsawg dua 0.25mm, thiab qhov tseeb qhov loj yog siab dua li ntawm cov yeeb nkab kub-dov seamless.
