Electric Arc Rauv
Lub tshuab hluav taws xob arc rauv siv qhov kub thiab txias tsim los ntawm hluav taws xob arc kom sov thiab yaj hlau, thiab yog ib qho ntawm feem ntau siv rauv hom hauv steelmaking. Raws li cov khoom siv hauv lub cev thiab cov yam ntxwv ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob arc tuaj yeem muab faib ua ntau zaus- hloov hluav taws xob arc rauv, resonant electric arc furnaces, thiab cov hluav taws xob arc rauv. Hluav taws xob arc furnaces muaj qhov zoo xws li cua kub ceev thiab tswj qhov kub thiab txias, thiab tsim nyog rau kev smelting thiab kev ua ntawm ntau yam hlau.
Hloov
Lub converter yog ib qho khoom siv uas siv lub tshuab ua kom sov lub cev los tsim cov hlau molten, feem ntau yog siv rau kev tsim cov hlau qis - carbon steel. Muaj ntau hom kev hloov pauv, suav nrog Tswb rauv taws, Sab saum toj furnaces, Krupp furnaces, thiab Olympus furnaces. Converter steelmaking muaj qhov zoo xws li kev ua haujlwm siab thiab kev siv hluav taws xob tsawg, thiab yog ib txoj hauv kev tseem ceeb hauv kev tsim cov hlau niaj hnub no.
Qhib -Hearth Rauv
Ib qho qhib -hearth furnace yog ib qho yooj yim steelmaking rauv, nrog ntau hom xws li tiaj tus -botomed boilers thiab kab rov tav furnaces. Qhib -heart furnaces muaj qhov nruab nrab melting kub thiab haum rau melting thiab cua sov hlau, cam khwb cia hlau, thiab steel billets. Qhib-heart furnaces muaj qhov zoo xws li kev ua haujlwm yooj yim thiab cov nqi tsim khoom tsawg, thiab tseem siv tau hauv qee lub tuam txhab hlau me thiab cov chaw tsim khoom.
Blast Rauv
Lub tshuab hluav taws xob tawg yog ib qho tseem ceeb tshaj plaws ntawm cov khoom siv hauv steelmaking, tus cwj pwm los ntawm kev ua haujlwm siab thiab kev ua haujlwm siab. Los ntawm cov txheej txheem xws li kev them nyiaj sab saum toj, lub tshuab ua kom lub cev txo qis, thiab hauv qab tapping, lub tshuab hluav taws xob hloov pauv hlau ore rau hauv npua hlau. Blast furnace ironmaking yog qhov txuas tseem ceeb hauv kev tsim cov hlau, thiab nws cov khoom tsim tawm thiab kev ua tau zoo ncaj qha cuam tshuam rau cov txheej txheem steelmaking thiab dov.
