Feem ntau, cov txheej txheem ntawm seamless steel kav yuav muab faib ua ob hom: txias thiab kub dov. Kub-dov, raws li lub npe qhia, qhov kub ntawm cov dov qhov chaw yog siab, yog li qhov deformation kuj yog me me, uas tuaj yeem ua tiav qhov loj deformation. Siv lub dov ntawm lub phaj steel ua piv txwv. Feem ntau, lub thickness ntawm lub casting dawb paug yog hais txog 230mm, thiab tom qab dov thiab refined dov, qhov kawg thickness yog 1 ~ 20mm. Nyob rau tib lub sij hawm, vim hais tias qhov dav piv ntawm cov hlau phaj me me, qhov loj thiab qhov yuav tsum tau muaj qhov tseeb yog qhov tsawg, nws tsis yooj yim los tshwm sim ntawm cov phaj-zoo li qhov teeb meem, feem ntau yog tswj cov convexity.
Cov txheej txheem ntawm cov kav dej txias-dov seamless steel feem ntau nyuaj dua li kub dov. Lub raj xa dej yuav tsum tau ua los ntawm peb lub rollers. Tom qab nyem, yuav tsum tau ua ib txoj kab uas hla ruaj khov. Txiav lub grim txog ib meter.
Cov txheej txheem kub-rolled yog raws li nram no:
Round raj → cua sov → perforation → peb-rolled oblique dov, nruam dov los yog squeezing → dehuminar → tsau txoj kab uas hla (los yog txo) → txias → ncaj → hydraulic kuaj (los yog kuaj) → kos npe → seamless steel kav rau hauv warehouse Nws yog ua los ntawm ib tug ingot los yog cov tube khoom dawb paug los ntawm perforation, thiab ces ua los ntawm kub dov, txias dov los yog txias. Cov specifications ntawm seamless steel kav yog sawv cev los ntawm txheej kab * phab ntsa thickness millimeters.
Seamless steel kav muab faib ua ob hom: kub dov thiab txias-dov (dial) seamless steel kav. Kub-dov seamless steel kav tau muab faib ua cov kav hlau dav dav, qis thiab qis-siab boiler steel kav, high-pressure boiler steel kav, alloy steel kav, stainless hlau kav, roj av cracking kav, geological steel kav thiab lwm yam steel kav. Txias dov (dial) seamless steel kav, ntxiv rau cov kav hlau dav dav, qis- nruab nrab-voltage boiler steel kav, siab-siab boiler steel kav, alloy steel kav, stainless hlau kav, roj av cracking kav, lwm yam steel kav, kuj muaj xws li carbon nyias -wall steel kav, alloy nyias -wall steel kav, thiab alloy nyias -wall steel kav, nyias alloyed steel kav, alloyed steel kav, thiab alloyed steel kav, alloyed steel kav, thiab nyias -walled steel kav, thiab nyias -walled steel kav, alloyed steel kav, Stainless nyias -walled steel kav, alien steel kav.
Sab nraud txoj kab uas hla ntawm cov kub dov seamless yeeb nkab yog feem ntau ntau dua 32 hli, phab ntsa thickness yog 2. 5}}.25mm, thiab sab nraud txoj kab uas hla ntawm cov phab ntsa nyias yuav tsawg dua 0.25mm. Rolling yog siab tshaj qhov kub-dov loj.
Feem ntau, seamless steel kav yog ua los ntawm high-alloy qauv steel los yog 40Cr, 30CRMNSI, 45mn2, 40MNB thiab lwm yam high-quality carbon knot steel 16mn thiab 5MNV xws li 10, 20, 30, 35, 45. 10, 20 seamless yeeb nkab los ntawm qis-carbon steel feem ntau yog siv rau cov kav dej thauj mus los.
Cov kav dej seamless ua los ntawm carbon steel hauv 45, 40Cr thiab lwm cov pa roj carbon steel yog siv los ua cov khoom siv kho tshuab xws li tsheb thiab tsheb laij teb. Feem ntau, seamless steel kav yuav tsum tau siv los xyuas kom meej lub zog thiab compression xeem. Cov yeeb nkab kub-dov hlau yog xa hauv lub xeev kub-dov los yog lub xeev kho kub; txias dov yog xa mus rau lub xeev kho kub.
