(1) Kev tsim cov hlau
Hlau yog tsim los ntawm hluav taws xob rauv, oxygen converter los yog qhib hearth txoj kev.
(2) Kev tsim cov txheej txheem ntawm lub raj khoob
Lub raj tsis muaj peev xwm ua tau los ntawm txoj kev kub dov, thiab ib qho kev nruam casting los yog steel ingot kuj siv tau.
(3) Kev tsim cov yeeb nkab steel
Cov yeeb nkab steel tuaj yeem tsim los ntawm kev kub dov (extrusion, expansion) lossis txias kos duab (dov) seamless txoj kev.

(1) Hydraulic xeem
Cov yeeb nkab steel yuav tsum tau kuaj hydraulically ib los ntawm ib qho.
(2) Flattening xeem
Cov kav hlau uas muaj txoj kab uas hla sab nraud ntawm ntau dua 22mm txog 400mm thiab phab ntsa tuab tsis tshaj 10mm yuav tsum raug kuaj kom haum.
(3) Flaring xeem
Cov yeeb nkab steel nrog phab ntsa thickness tsis ntau tshaj 8 hli tuaj yeem raug kuaj flare nrog rau sab saum toj taper ntawm 30 °, 45 ° lossis 60 °.
(4) Khoov kuaj
Cov kav hlau uas muaj txoj kab uas hla sab nraud tsis tshaj 22 hli yuav raug rau kev sim khoov.
(5) Kev kuaj tsis muaj kev puas tsuaj
Raws li cov kev xav tau ntawm tus neeg yuav khoom, cov yeeb nkab steel yuav raug kuaj ultrasonically ib qho los ntawm ib qho.
