Kev siv thiab siv cov graphite electrodes hauv hluav taws xob arc rauv smelting (3)
Apr 15, 2022
Cov yam ntxwv cuam tshuam rau kev noj cov graphite electrodes hauv smelting
Lub tshuab hluav taws xob arc rauv smelting nyob rau hauv cov txheej txheem steelmaking yog muab faib ua roughing thiab refining, tab sis cov graphite electrodes hloov hluav taws xob hluav taws xob mus rau hauv lub cub hluav taws xob thiab hloov nws mus rau hauv lub zog hluav taws xob kom ua tiav lub hom phiaj ntawm cua sov thiab melting cov khoom nqi. Rough smelting yog txheej txheem oxidation rau lub hom phiaj ntawm melting seem steel thiab tso cov pa phem thiab impurities, thaum refining kuj yog ib tug txo tus txheej txheem uas kho steel ntsiab thiab tshem tawm cov roj thiab impurities los ntawm cua sov. Nws tuaj yeem pom tau tias lub tshuab hluav taws xob arc rauv smelting yog siv cov graphite electrode los kho cov cua sov kom paub txog cov tshuaj tiv thaiv redox thiab ua tau raws li cov kev cai ntawm cov txheej txheem steelmaking. Kev noj cov graphite electrode hauv smelting tuaj yeem muab faib ua active noj, natural noj lossis technology noj. Reactive hwj chim noj yog lub cev noj uas tsis koom nyob rau hauv lub cua sov txheej txheem los yog tsis koom nyob rau hauv lub cua sov txheej txheem kiag li, thiab kuj yog tsis siv technology.
Lub ntsiab tseem ceeb cuam tshuam rau kev noj cov graphite electrodes
Kev noj cov graphite electrodes nyob rau hauv hluav taws xob rauv steelmaking sau los ntawm tag nrho cov txheej txheem smelting, thiab nws noj yog cuam tshuam los ntawm ntau yam. Ntawm no, tsuas yog kev ua haujlwm ntawm cov txheej txheem smelting yog txheeb xyuas.
(1) Cov khoom seem tsis zoo lossis qhov sib piv tsis zoo ua rau cov nyhuv slaging tsis zoo thiab lub sijhawm ntev smelting; Qhov nce ntawm lub sijhawm pub mis thiab lub sijhawm nkag mus zoo ua rau muaj kev puas tsuaj thiab puas tsuaj ntawm electrode hauv qab. Lub sij hawm smelting ntev dua yog qhov ncaj qha ua rau kev siv hluav taws xob ntau ntxiv thiab siv hluav taws xob thiab poob.
(2) Cov khoom siv hluav taws xob hluav taws xob hluav taws xob tsis sib xws rau cov khoom siv hluav taws xob thiab ntau yam
Hluav taws xob arc rauv hluav taws xob xa khoom yog qhov ua haujlwm siab tam sim no, tsis tshua muaj hluav taws xob ua haujlwm. Yog tias lub peev xwm ntawm cov khoom siv hluav taws xob loj dhau lawm thiab tshaj qhov txwv tsis pub thauj khoom ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob hauv 5 ~ 10min ntawm lub arc yuav tshwm liab los ntawm hauv qab mus rau sab saum toj, ciam teb ntawm kev sib txuas yog pom tseeb heev thiab feem ntau ntawm lawv. muaj kev sib tsoo; qhov tam sim no siab dhau los yog qhov hloov pauv loj heev, qhov tawg zaus ntawm cov pob qij txha ntawm cov pob qij txha yog nce thiab qhov kev noj qab haus huv hauv qab yog tapered. Yog tias lub peev xwm muab hluav taws xob qis qis, qhov kub ntawm qhov cub yuav tsis ua raws li cov txheej txheem yuav tsum tau ua nyob rau hauv lub sijhawm nruab nrab kub, thiab kev ua haujlwm yuav qeeb. Kev poob thiab kev siv ntawm graphite electrode yog qhov loj tshaj plaws hauv kev ua haujlwm dhau sijhawm thiab ua haujlwm dhau sijhawm.
(3) Lub sijhawm oxidation raug yuam kom muaj zog tshuaj lom neeg thiab txhim kho smelting zog
Hauv smelting, cov pa oxygen tshuab (feem ntau tsawg dua 45M3 / T) raug quab yuam kom ua tiav sai sai thiab ua kom lub cub tawg kub, uas yooj yim ua rau lub qhov cub txias thiab qhov cub thiab lub cub tawg yog nyob rau hauv lub xeev nplua nuj, yog li ntawd txhua theem electrode nyob rau hauv ib tug kub kub nplaim taws. Thaum cov electrodes nyob rau hauv qhov cub qhov cub, feem ntau ntawm lawv muaj qhov tshwm sim loj ntawm txheej txheej thiab oxidation nto.
(4) Cov txheej txheem ntawm kev teeb tsa thiab kev ua haujlwm ntawm lub tshuab hluav taws xob
Muaj qhov sib txawv tseem ceeb ntawm eAF niaj hnub thiab ib txwm eAF. Qhov tshwm sim ntawm ultra-siab zog loj-scale EAF thiab kub them steelmaking txheej txheem txhim kho smelting siv thiab ntau lawm muaj peev xwm, thiab yog li tso rau pem hauv ntej siab dua cov kev cai rau qhov zoo ntawm graphite electrode. Thaum lub sijhawm ua haujlwm, qhov kev xaiv ntawm lub zog xa hluav taws xob nkhaus thiab iav, kev tswj ntawm arc pib thiab arc stabilizing voltage thiab tam sim no, kev siv lub sijhawm ntev, nruab nrab thiab luv arcs, kev teeb tsa thiab kev siv dej txias tag nrho ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm. kev pab cuam lub neej thiab kev siv ntawm electrode.
(5) Zoo ntawm graphite electrodes
Tam sim no, smelting thiab txheej txheem ntawm hluav taws xob arc rauv muaj ntau thiab ntau muaj zog yuav tsum tau rau lub anti-oxidation kev ua tau zoo thiab thermal poob siab tsis kam ntawm graphite electrodes, thiab lub siab noj los ntawm zoo fluctuation tau attracted zoo mloog los ntawm cov neeg siv ncaj qha. Yog li ntawd, qhov sib npaug thiab ruaj khov ntawm graphite electrode zoo yog qhov tseem ceeb tshaj plaws hauv kev txiav txim siab noj.
