UHP graphite electrode 650 * 2700 hli
Ultra-high-power graphite electrodes yog tsim rau loj-scale ultra-high-power hluav taws xob arc rauv, ntau tshaj 50 tons ntawm hluav taws xob arc rauv;Lub voj voog smelting yog 25% luv dua li lub zog hluav taws xob zoo tib yam hluav taws xob arc rauv, txo kev siv hluav taws xob thiab txhim kho kev tsim khoom.Cov nram qab no Dan charcoal graphite electrode yuav qhia txog kev siv ultra-siab zog graphite electrode thiab cov txheej txheem thiab ultra-siab zog graphite electrode.
Lub zog ultra-siab graphite electrode yog ua los ntawm cov koob zoo coke, uas yog tsim los ntawm ntau tshaj li kaum ob txheej txheem xws li calcination, extrusion, impregnation, graphitization thiab machining.ntev.Nws tso cai rau qhov ceev tam sim no ntau dua 25A / cm2, thiab feem ntau yog siv rau smelting zoo hlau thiab hlau tshwj xeeb.
Nyob rau hauv thaum ntxov hnub, domestic ultra-high-power graphite electrodes cia siab rau kev ntshuam.Vim yog kev lag luam thev naus laus zis ntawm cov teb chaws tsim kho hauv Europe, Amelikas thiab Nyij Pooj, kev tsim khoom hauv tsev tau deb ntawm qhov kev thov.Nrog rau txoj kev loj hlob ntawm kev lag luam steel, ntau graphite electrode
cov tuam txhab tau nqis peev nyiaj ntau thiab thev naus laus zis hauv R & D thiab tsim cov khoom siv hluav taws xob ultra-siab graphite electrodes.Dan charcoal graphite electrodes tau ua tiav UHP700mm ultra-siab zog graphite electrodes los muab txawv teb chaws steel mills nrog tsim nyog sim thiab ntau lawm.UHP800mm tau tsim tag nrho.Ultra-siab zog graphite electrodes.
Hluav taws xob rauv steelmaking yog cov neeg siv loj ntawm graphite electrodes.Kuv lub teb chaws cov hluav taws xob rau hluav taws xob steel ntau lawm suav txog 18% ntawm cov khoom siv hlau tsis zoo, thiab graphite electrodes rau steelmaking account rau 70% mus rau 80% ntawm tag nrho cov graphite electrode noj.Hluav taws xob rauv steelmaking yog siv graphite electrodes los qhia tam sim no rau hauv lub cub tawg, thiab siv cov kub kub qhov chaw uas tsim los ntawm lub arc ntawm lub electrode kawg thiab tus nqi rau smelt.
Lub submerged thermal hluav taws xob rauv yog tsuas yog siv rau zus tau tej cov silicon thiab daj phosphorus, thiab lwm yam. Nws yog characterized nyob rau hauv lub qis ib feem ntawm cov conductive electrode yog faus rau hauv tus nqi, ib tug arc yog tsim nyob rau hauv tus nqi txheej, thiab lub tshav kub. lub zog tawm los ntawm tus nqi nws tus kheej kuj yog siv los ua kom sov tus nqi.Submerged arc furnaces nrog ntau dua yuav tsum siv graphite electrodes.Piv txwv li, kwv yees li 100kg ntawm graphite electrodes yog siv rau kev tsim 1t ntawm silicon, thiab txog 40kg ntawm graphite electrodes yog siv los ua 1t ntawm daj phosphorus.
Graphitization furnaces rau zus tau tej cov khoom graphite, melting furnaces rau melting iav, thiab hluav taws xob rauv rau zus tau tej cov silicon carbide yog tag nrho cov kuj furnaces.Cov ntaub ntawv nyob rau hauv lub cub tawg yog ob qho tib si cua sov resistors thiab cov khoom yuav tsum tau rhuab.Feem ntau, cov conductive graphite electrodes yog embedded nyob rau hauv qhov kawg ntawm qhov hluav taws kub kuj.Nyob rau hauv lub cub tawg lub taub hau phab ntsa nyob rau hauv qab, cov graphite electrodes siv no yog discontinuously noj.
Cov blanks ntawm graphite electrodes kuj yog siv los ua ntau yam khoom zoo li graphite xws li crucibles, pwm, nkoj thiab cua sov.Piv txwv li, hauv kev lag luam quartz iav, 10 tons ntawm graphite electrode blanks yog xav tau rau txhua 1 tuj ntawm hluav taws xob fusion yeeb nkab tsim;100 kg ntawm graphite electrode blanks yog xav tau rau txhua 1 tuj ntawm quartz cib tsim.
Raws li lub tshuab hluav taws xob hluav taws xob hluav taws xob hluav taws xob, nws tau muab faib ua lub zog hluav taws xob zoo tib yam hluav taws xob hluav taws xob hluav taws xob (tsawg dua 400kV.A / t), hluav taws xob hluav taws xob hluav taws xob siab hluav taws xob (400kV.A / t ~ 700kV.A / t), ultra-siab zog hluav taws xob arc rauv (tshaj 700kV.A/t).Raws li lub hauv paus ntsiab lus ntawm lub hwj chim hluav taws xob hluav taws xob arc rauv yog txuam nrog lub hwj chim graphite electrode, ultra-siab zog graphite electrode yog siv nrog ultra-siab zog hluav taws xob arc rauv.
YB/T 4088-2015 Graphite Electrode Txuj
"YB/T4089-2015 High Power Graphite Electrode Standard"
"YB/T4090-2015 Ultra-siab zog Graphite Electrode Standard"
Cov txheej txheem tsim khoom ntawm graphite electrodes yog tsim los ntawm cov khoom siv raw calcination, cov khoom siv extrusion, dipping thiab roasting, graphitization thiab mechanical processing.Muaj qee qhov sib txawv ntawm lub voj voog ntau lawm thiab cov khoom siv raw ntawm electrodes nrog lub zog sib txawv.
