(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.
