Navigation Khawm
txheej txheem ntawm kub dov
Raw khoom npaj → Cua sov → Perforation → Rolling → Elongation → Sizing thiab phab ntsa txo → Thaum tshav kub kub kho → Straightness kho → soj ntsuam thiab kuaj → Txiav thiab tiav cov khoom soj ntsuam → Anti-corrosion kho
Raw khoom npaj: Billets yuav tsum tau ntxuav kom huv si kom tshem tawm cov oxides lossis lwm yam impurities ua ntej tsim khoom.
Cua sov: Lub billet yog muab tso rau hauv lub qhov cub cua sov kom sov rau qhov tsim nyog kub, uas feem ntau yog siab tshaj 1200 ℃.
Perforation: Lub rhuab billet yog pub rau hauv lub tshuab perforating, uas perforates nws los ua ib tug hollow billet.
Rolling: Tom qab tho, lub billet nkag mus rau hauv lub tshuab dov.Lub billet kis tau los ntawm ntau khub ntawm yob uas tsis tu ncua txo qhov sab nraud txoj kab uas hla thiab nce qhov ntev ntawm lub billet.
Elongation: Lub billet yog txuas ntxiv los ntawm txoj kev elongator kom ua tiav cov ntsiab lus meej dua.
Qhov loj me thiab phab ntsa txo: Sizing thiab phab ntsa txo cov billet nyob rau hauv lub tshuab sizing kom ua tiav qhov kawg tshwj xeeb loj thiab phab ntsa thickness.
Kev kho cua sov: cov yeeb nkab xav tau kev kho cua sov los kho nws lub koom haum hlau thiab txhim kho cov khoom siv kho tshuab, suav nrog cov txheej txheem normalizing thiab annealing.
Kev kho qhov ncaj: Cov yeeb nkab raug kho los ntawm lub tshuab ncaj nraim kom ntseeg tau qhov ncaj ntawm cov yeeb nkab.
Kev tshuaj xyuas thiab kev sim: Ntau yam kev tshuaj xyuas thiab kev ntsuam xyuas tau ua tiav ntawm cov yeeb nkab uas tsis muaj seamless, xws li hydrotest, kuaj ultrasonic, eddy tam sim no kuaj, thiab lwm yam.
Txiav thiab tiav cov khoom soj ntsuam: Txiav cov hlab rau hauv qhov ntev raws li cov neeg siv khoom xav tau thiab ua qhov kev soj ntsuam zaum kawg thiab qhov ntev.
Anti-corrosion kho: Yog tias tsim nyog, seamless steel yeeb nkab yog coated nrog anti-corrosion roj los yog lwm yam kev kho corrosion, xws li galvanized; 3LPE, FBE thiab lwm yam.
Kev tsim cov txheej txheem txias-draw
Billet yeeb nkab npaj → Annealing kev kho mob → Pickling thiab lubrication → Txias kos duab → Thaum tshav kub kub kho → Straightness kho → soj ntsuam thiab kuaj → txiav thiab tiav cov khoom soj ntsuam → Anti-corrosion kho
Billet yeeb nkab npaj: Xaiv qhov tsim nyog kub dov seamless steel yeeb nkab ua raw khoom, piv txwv li cov yeeb nkab pib billet.
Annealing kev kho mob: Txhawm rau tshem tawm cov kev ntxhov siab uas tsim los ntawm cov txheej txheem kub dov ntawm cov kav dej, cov kav dej billet feem ntau yuav tsum tau muab tshem tawm.
Pickling thiab lubrication: Tom qab annealing, cov raj yuav tsum tau muab tshem tawm kom tshem tawm cov tawv nqaij oxidized thiab xeb.Tom qab ntawd, cov khoom siv lubricating yog siv rau lub raj nplaim kom txo qis kev sib txhuam thiab hnav thaum lub caij txias txias.
Txias daim duab: Cov yeeb nkab billet tau muab tso rau ntawm lub tshuab kos duab txias thiab ncab los ntawm kev tuag, cov txheej txheem uas txo txoj kab uas hla ntawm cov yeeb nkab nrog rau kev txhim kho qhov chaw tiav thiab qhov tseeb.
Tom qab ntawd, kev kho cua sov thiab lwm cov txheej txheem ntau lawm yog tib yam li kub dov, thiab yuav tsis rov ua dua ntawm no.
Yuav ua li cas sib txawv ntawm kub dov thiab txias kos seamless steel yeeb nkab, koj tuaj yeem tsom rau cov yam ntxwv yooj yim hauv qab no:
| Sau npe | kub dov | khaub thuas kos duab |
| Qhov tshwm sim | Qhov saum npoo yog rougher thiab tej zaum yuav muaj oxidized ntawm daim tawv nqaij thiab ntau defects xws li khawb, pockmarks, thiab dov indentations | Zoo nto tiav, feem ntau smoother thiab ci dua kub dov steel yeeb nkab |
| Sab nraud txoj kab uas hla (OD) | OD≥33.9 | OD 33.9 |
| Phab ntsa Thickness | 2.5-200 hli | 0.25-12 hli |
| Ua siab ntev | Yooj yim rau cov phab ntsa tsis sib xws thiab ovalization | Uniform txheej txheej phab ntsa thickness nrog me me kam rau ua |
| Nqe | Tus nqi qis rau tib lub sijhawm | Tus nqi siab dua rau tib lub sijhawm |
