Cored hlau txhim khu muaj peev xwm alloying
Los ntawm kev sivcored kab, steelmakers muaj peev xwm nce lawv cov peev xwm alloying.
Cov xov hlau flux-cored no tau ntim nrog ntau yam alloying ntsiab lus, xws li hlau alloys, uas tau tso rau hauv cov hlau molten thaum lub sij hawm refining txheej txheem.
Qhov no tso cai rau kev ua tib zoo hloov cov ntsiab lus alloying, kom ntseeg tau tias cov tshuaj lom neeg muaj pes tsawg leeg thiab coveted steel khoom tiav. Daim ntawv thov ntawm cored hlau thev naus laus zis tso cai rau cov tuam txhab tsim kho kom yooj yim kho cov ntsiab lus alloying los txhim kho qhov zoo thiab kev ua haujlwm ntawm cov hlau.
