Dab tsi yog steelmaking hauv nruab nrab zaus cua sov?

“Seem tau yaj los ntawm lub tshuab ua kom sov nruab nrab, thiab tom qab ntawd ua kom zoo dua mus rau qhov txuas ntxiv mus” yog hu ua txheej txheem luv. Cov txheej txheem luv luv tsis xav tau cov txheej txheem hlau ua ntej thiab ua rau lub tshuab ua kom tawg hlau ua kom sov. Yog li ntawd, txheej txheem yooj yim, kev nqis peev tsawg, thiab lub sijhawm tsim kho yog luv. Txawm li cas los xij, cov txheej txheem kev tsim khoom luv luv yog qhov me me, qhov ntau ntawm cov khoom tsim tawm yog qhov nqaim, thiab tus nqi tsim khoom kuj tseem siab. Tib lub sijhawm, nws raug txwv los ntawm kev muab cov hlau seem.

Cov txheej txheem luv

Cov txheej txheem tsim khoom ntawm cov hlau me me cog rau ntawm qhov nruab nrab zaus ua kom sov cov txheej txheem steelmaking. Cov hlau seem uas tau rov qab los yog raug tsoo, txheeb thiab ua tiav, thiab tom qab ntawd muab tso rau hauv lub tshuab ua kom sov nruab nrab. Cov cua sov nruab nrab nruab nrab melts cov seem, tshem tawm cov khoom tsis huv (xws li phosphorus thiab sulfur), thiab tom qab ntawd siv cov hlau, thiab tom qab ntawd tau txais cov hlau uas tsim nyog los ntawm kev ua kom zoo dua qub. Nws tau khov kho thiab tsim los ntawm kev nruam nrum los ua cov hlau hlau, uas tau hloov pauv mus rau hauv cov khoom siv hlau tom qab txheej txheem dov.
