Nyob rau hauv lub ntiaj teb ntawm cov hlau tshwj xeeb heev, kev ua raws li txhua yam . ib feem pua uas tsis muaj kev puas tsuaj rau cov neeg tuaj yeem ua haujlwm thiab cov hlau tsis muaj peev xwm.Tshob Refining Rauv(LRF) - Feem ntau hu ua "Chaw Tswjhwm Zoo" ntawm cov steel nroj - hloov pauv hlau zoo rau hauv cov hlau tshwj xeeb {}}
Cov lus qhia no yuav coj koj sab hauv LRF txoj haujlwm nrog:
Kauj ruam-theem-qib rhuav tshem ntawm cov txheej txheem ua kom zoo dua
Tiag tiag-ntiaj teb cov piv txwv ntawm kev hloov kho thaum ub kev hloov kho
Txiav-ntug kev nrhav zoo li i-pab alloy trimming
Tus nqi / Kev sib piv zoo VS cov kev coj ua
LRF nyob rau hauv cov ntsiab lus teb: Vim li cas cov lus qhia ntxiv yog tsis muaj kev sib ceg
Cov kev txwv ntawm thawj steelmaking
Thaum hluav taws xob arc rauv (EAF) Excel ntawm melting seem, lawv tawm tsam nrog:
Ua kom meej kawg Chemistry tswj (± 0.05% kev sib txawv)
Kev siv desulfurization (feem ntau EFS tsuas yog ua tiav ~ 0.025% s)
Cov homogeneity (tseem ceeb rau kev nruam nruam)
Txoj kev daws teeb meem LRF
Xav txog ib qho LRF yog "phais suite" qhov twg:
Cov hluav taws xob muab rov qab (them nyiaj rau kev poob kub)
Argon bubbling tsim ib "steel whirlpool" rau kev sib xyaw
Alloy pub cov khoom siv cov khoom siv nrog cov ntawv ntsuas qib
Lub ntiaj teb tiag tiag analogy: Yog tias EAF steelmaking zoo li ua noj ua haus stew, LRF yog tus kws ua zaub mov noj uas hloov kho seasoning rau gram ua ntej pab .

Niaj hnub no LRFs tsis yog tsuas yog "tso cua sov pw" - lawv tau qhov sib txawv ntawm:
Cov khoom lag luam hlau muag los ntawm lub tuj
Hwm Steel muag los ntawm gram
