Ib qho hluav taws xob arc rauv (EAF) yog arauvuas heats nqi khoom siv los ntawm ib tughluav taws xob arc.
Industrial arc furnaces muaj qhov loj me los ntawm cov chav me me ntawm kwv yees li ib qhotonmuaj peev xwm (siv hauvchaw tsim khoomrau kev tsim khoomnrum hlaukhoom) txog li 400 tuj units siv rau theem nrabsteelmaking. Arc furnaces siv nyob rau hauv kev tshawb fawb soj ntsuam thiab los ntawmkws kho hniavtej zaum yuav muaj peev xwm tsuas yog ob peb lub kaum os grams. Muaj hluav taws xob arc rauv kub tuaj yeem ncav cuag 1,800 degree (3,272 degree F), thaum chav kuaj tuaj yeem tshaj 3, 000 degree (5,432 degree F).
Arc furnaces txawv ntawminduction cua sovNyob rau hauv hais tias cov khoom siv yog raug ncaj qha mus rau ib tug hluav taws xob arc, thiab cov tam sim no nyob rau hauv lub cub tawg terminals dhau los ntawm cov khoom them.
Nyob rau hauv lub xyoo pua 19th, ib tug xov tooj ntawm cov txiv neej tau ua hauj lwm ib tug hluav taws xob arc kom yajhlau. YawgHumphry Davytau ua ib qho kev sim ua qauv qhia xyoo 1810; welding tau tshawb xyuas los ntawm Pepys hauv 1815; Pinchon sim tsim lub tshuab hluav taws xob hluav taws xob hauv xyoo 1853; thiab, xyoo 1878–79, SirWilliam Siemenscoj tawmpatentsrau hluav taws xob furnaces ntawm hom arc.
Thawj qhov hluav taws xob arc rauv tau tsim los ntawmPaul Héroult, ntawmFabkis, nrog ib tug coj mus muag nroj tsuag tsim nyob rau hauv lubTebchaws MeskasXyoo 1907. Cov kwv tij Sanderson tau tsim lub Sanderson Brothers steel Co. hauv Syracuse, New York, txhim kho thawj lub tshuab hluav taws xob hluav taws xob hauv Teb Chaws Asmeskas Lub cub tawg tam sim no tau nthuav tawm ntawm Chaw nres tsheb Square, Pittsburgh, Pennsylvania.Initial "hluav taws xob steel" yog ib qho tshwj xeeb. cov khoom siv rau kev siv xws litshuab cuab yeejthiabcaij nplooj ntoos hlav steel. Arc furnaces kuj tau siv los npajcalcium carbidesiv rau hauvcarbide teeb. CovStassano hluav taws xob rauvyog hom arcrauvuas feem ntau tig los sib tov da dej. Lub qhov cub Girod zoo ib yam li lub qhov cub Héroult.
Thaum EAFs tau siv dav hauv Ntiaj Teb Tsov Rog II rau kev tsim cov hlau hlau, nws tsuas yog tom qab ntawd cov hluav taws xob steelmaking pib nthuav dav. Tus nqi qis rau ibmini-mills- ib ncig ntawm US $ 140-200 ibtonntawm lub peev xwm nruab ib xyoos ib zaug, piv nrog US $ 1, 000 ib tuj ntawm txhua xyoo nruab peev rau ib qhointegrated steel zeb- tso cai rau cov mills kom tsim tau sai sai hauv kev ua tsov ua rog nyob sab Europe, thiab tseem tso cai rau lawv kom ua tiav kev sib tw nrog cov loj.Tebchaws Meskassteelmakers, xws liBethlehem SteelthiabUS Steel, rau tus nqi qis,carbon hlau"Long khoom" (steel qauv, thiab bar,hlau, thiabfasteners) hauv Teb Chaws Asmeskas kev lag luam.
Thaum twgNucor-tam sim no yog ib lub tuam txhab loj tshaj plaws nyob rau hauv Teb Chaws Asmeskas tau txiav txim siab nkag mus rau cov khoom lag luam ntev hauv xyoo 1969, lawv tau xaiv los pib lub tshuab hluav taws xob me me, nrog rau EAF ua nws lub cub tawg, tsis ntev tom qab ntawd los ntawm lwm cov tuam txhab. Txawm hais tias Nucor nthuav dav sai nyob rau sab hnub tuaj Asmeskas, cov tuam txhab uas ua raws lawv mus rau hauv kev ua haujlwm me me tau tsom mus rau kev lag luam hauv zos rau cov khoom lag luam ntev, qhov uas siv EAF tso cai rau cov nroj tsuag sib txawv ntau lawm raws li qhov xav tau hauv zos. Cov qauv no kuj tau ua raws li thoob ntiaj teb, nrog EAF steel ntau lawm feem ntau siv rau cov khoom siv ntev, thaum sib xyaw ua ke, sivtawg rauvthiabyooj yim oxygen furnaces, cornered lub lag luam rau "cov khoom tiaj tus"-daim hlauthiab hnyav hlau phaj. Xyoo 1987, Nucor tau txiav txim siab nthuav dav rau hauv cov khoom lag luam tiaj tus, tseem siv EAF txoj kev tsim khoom.
