Kev tsim cov kav dej seamless steel ua raws li cov txheej txheem kub dov tas li tsim los ua kom cov khoom siv sib xws, ruaj khov qhov tseeb, thiab txhim khu kev qha sab hauv. Cov txheej txheem hauv qab no yog dav siv rau kev tsim cov pa roj carbon steel thiab alloy steel seamless kav xws li ASTM A106, ASTM A53, thiab ASTM A335 qib.
Txheej txheem txheej txheem
Seamless steel yeeb nkab ntau lawm yog ua los ntawm kev tswj cov cua sov, tho, dov, sizing, kho cua sov, thiab tshuaj xyuas. Txhua theem ncaj qha cuam tshuam qhov kev ua tau zoo kawg ntawm cov yeeb nkab hauv siab thiab kev siv cov qauv.
Manufacturing Flow
1. Cua sov hauv Rotary Hearth Rauv
Steel billets yog rhuab mus rau ib tug uniform siab kub kom tiav yas deformation muaj peev xwm yuav tsum tau rau tho.
2. Kev tho
Lub rhuab billet yog pierced los ua ib tug hollow plhaub (niam raj), uas yog thawj kauj ruam nyob rau hauv tsim ib tug seamless qauv.
3. Dov hauv Mandrel Mill
Lub plhaub hollow yog elongated thiab phab ntsa thickness yog tswj los ntawm ib tug mandrel -txhawb txheej txheem dov, txhim kho qhov sib xws.
4. Rov ua dua
Lub semi-tiav lawm raj yog reheated kom tswj kom haum dov kub rau cov txheej txheem txo ntxiv.
5. Kev txo qis
Ntau- sawv ntsug ncab txo cov mills yog siv los kho qhov kawg sab nraud txoj kab uas hla thiab phab ntsa tuab, tso cai rau ntau qhov loj me specifications.
6. Txias ntawm lub txaj txias
Kev tswj cov cua txias yog siv los ua kom cov qauv hlau ruaj khov thiab tiv thaiv kom tsis txhob deformation lossis kev ntxhov siab seem.
7. Ncaj nraim
Cov yeeb nkab yog mechanically straightened los xyuas kom meej ncaj siab kam rau ua yuav tsum tau rau industrial installation.
8. Ultrasonic & Eddy Kev Ntsuas Tam Sim No
Tsis yog-kev kuaj kev puas tsuaj yog ua los xyuas kom pom qhov tsis xws luag sab hauv thiab saum npoo xws li tawg, suav nrog, lossis laminations.
9. Kev soj ntsuam zaum kawg & ntim
Dimensional checks, marking, despection, and export -qib ntim tau ua tiav ua ntej xa khoom.
Cov ntsiab lus
Txoj kev tsim khoom no ua kom cov kav dej seamless steel ua tau zoo raws li lawv qhov ntev, ua rau lawv haum rau siab -siab, siab - kub, thiab kev siv cov qauv hauv kev lag luam.
