Graphite electrode txog lub siab - tiv thaiv cov khoom siv, sib xyaw, imprination, imprination, impration, graphitization, graphitization, kev ua tshuab. Nws yog hu ua Kev Lom Zem Graphite (raug xa mus ua graphite electrode), uas yog txawv ntawm lub ntuj graphite electrode li cov graphite graphite raws li cov khoom siv raw.
Graphite hluav taws xob yog tsim los ntawm roj coke thiab koob coke raws li cov ntaub ntawv raw, nrog cov ntaub ntawv sib tw ua ke. Lawv tau ua los ntawm kev cais tawm, batching, sib tov, moulding, ci, ci, graphitization, thiab machining. Lawv yog tus neeg tso tawm lub zog hluav taws xob hauv daim ntawv ntawm Arc hauv lub tshuab hluav taws xob ua kom sov thiab yaj cov khoom siv hluav taws xob. Raws li lawv cov ntsuas kev ua tau zoo, lawv tuaj yeem muab faib ua cov hluav taws xob zoo tib yam hluav taws xob, thiab ultra {4} high zog graphite hluav taws xob.
Cov khoom siv tseem ceeb rau kev tsim cov graphite hluav taws xob yog roj coke. Ib qho me me ntawm asphalt Coke tuaj yeem ntxiv rau cov hluav taws xob zoo li qub hluav taws xob, thiab cov Sulfur cov ntsiab lus ntawm ob lub roj av coke thiab asphalt coke thiab asphalt coke tsis pub dhau 0.5%. Koob coke kuj yuav tsum tau thaum ua qhov siab- power lossis ultra muaj zog graphite electrodes. Cov khoom siv tseem ceeb rau kev tsim cov tshuaj txhuas anrodes yog roj av coke, thiab cov neeg Sulfur cov ntsiab lus yog tswj hwm yuav tsis muaj ntau tshaj 1.5% mus rau 2%. Roj av coke thiab asphalt coke yuav tsum ua raws li cov qauv kev zoo hauv tebchaws.
Qhov zoo ntawm graphite electrode
(1) Qhov kev hloov pauv ntawm cov khoom lag luam thiab cov khoom siv sib txawv ntawm cov khoom siv cov khoom lag luam tau coj mus rau qhov kev tawm ntawm cov khoom siv txim. Qhov zoo ntawm graphite electrodes yog tias lawv yooj yim rau cov txheej txheem, muaj lub siab tshem tawm cov nqi tshem tawm, thiab muaj qis graphite poob. Yog li ntawd, qee pab pawg raws li cov neeg siv hluav taws xob cov neeg yuav khoom tau tso cov hluav taws xob liab thiab hloov mus rau graphite electrodes. Tsis tas li ntawd, qee cov qauv tshwj xeeb zoo nkauj tsis tuaj yeem ua los ntawm tooj liab, tab sis graphite yog qhov yooj yim rau daim ntawv, thiab tooj liab hluav taws xob tau hnyav dua thiab tsis haum rau kev ua cov ntawv loj loj. Cov xwm txheej tau coj qee pawg raws li cov neeg siv hluav taws xob raws li cov neeg siv hluav taws xob siv graphite electrodes.
(2) Graphite electrodes yog yooj yim rau cov txheej txheem thiab muaj kev sim ua nrawm dua li cov hluav taws xob tooj liab. Piv txwv li, siv cov thev naus laus zis los ua cov txheej txheem graphite yog 2- 3 zaug tsis tas yuav tsum tau ua dua qub, thaum lub thawv tooj liab ntxiv tau txais los ntawm kev tuav cov hniav sib tsoo. Ib yam li ntawd, yog cov high-ceev graphite machining chaw yog siv los tsim cov khoom siv hluav taws xob, kev ua tau zoo dua, thiab yuav tsis muaj teeb meem hmoov av. Hauv cov txheej txheem no, xaiv cov cuab yeej uas tsim nyog hardness thiab graphite tuaj yeem txo cov khoom hnav thiab puas rau tooj liab hluav taws xob. Yog tias peb piv lub sijhawm milling ntawm graphite electrodes thiab tooj liab cov hluav taws xob, graphite cov hluav taws xob yog 67% nrawm dua li cov hluav taws xob liab. Feem ntau, hauv hluav taws xob tshem tawm cov tshuab machining, siv graphite electrodes yog 58% nrawm dua li siv cov hluav taws xob tooj liab. Nyob rau hauv txoj kev no, kev ua lub sijhawm ua haujlwm tau txo qis, thaum tsim cov nqi tsim khoom kuj tau txo.
(3) Cov qauv tsim ntawm graphite hluav taws xob yog txawv ntawm qhov ntawd ntawm cov tsoos tooj liab hluav taws xob. Ntau cov cim pwm feem ntau muaj cov nyiaj tshwj xeeb tshwj xeeb rau cov khoom siv tooj liab thiab siv hluav taws xob tooj liab, uas txo tus naj npawb ntawm cad / cam thiab tshuab ua tiav. Qhov no ib leeg yog txaus kom tau zoo txhim kho qhov tseeb ntawm cov khoom noj kab noj qab hniav.
Daim ntawv thov ntawm graphite electrode
(1) siv rau hluav taws xob arc steel hlau steel hlau
Hluav taws xob rauv stat steelmakaking yog ib tug neeg siv loj ntawm graphite electrodes. Kev tsim cov hluav taws xob rauv steel hauv Tuam Tshoj cov nyiaj tau siv hauv cov roj steelmaking rau 70% rau 80% ntawm tag nrho cov nqi ntawm graphite hluav taws xob siv. Hluav taws xob hluav taws xob steelmakaking yog cov txheej txheem ntawm kev siv graphite electrodes los qhia tam sim no rau lub qhov cub los tsim los ntawm cov hluav taws xob ntawm lub electrode thiab lub cub hluavtaws rau smelting.
(2) siv rau cov ntxhia thermal fais rauv
Cov ntxhib pob hluav taws xob fais yog mas ntau lawm siv rau kev tsim khoom silicon thiab daj phosphorus. Lawv tus cwj pwm yog qhov qis dua ntawm cov khoom siv hluav taws xob tau faus, thiab siv lub zog cua sov tawm los ntawm cov khoom siv hluav taws xob, thiab siv cov cua sov tawm ntawm cov khoom siv hluav taws xob nws tus kheej kom sov cov khoom siv hluav taws xob. Ntawm lawv, cov ntxhia thermal fais rauv hluav taws xob nrog siab ntoj ntom ntom tam sim no xav tau graphite electrodes. Piv txwv li, txog 100kg ntawm graphite electrodes tau noj rau kev tsim cov khoom lag luam 1kg ntawm graphite cov hluav taws xob tau noj rau kev tsim tawm 1 nyhav ib tuj ntawm daj phosphorus.
(3) siv rau kev ua kom sov
Cov duab ntxoo hluav taws xob rauv siv rau kev tsim cov khoom lag luam graphite, thiab hluav taws xob rauv taws ua rau kev tsim cov silicon carbide txhua lub sij hawm yog los ua kom muaj cua sov. Cov ntaub ntawv sab hauv lub cub tawg yog ob qho kub tiv thaiv thiab cov khoom yuav tsum muaj cua sov. Feem ntau, graphite electrodes rau kev ua tau zoo yog embedded nyob rau hauv lub taub hau rauv taws ua kom tsis txhob muaj kev txwv ntawm graphite electrodes.
(4) siv rau kev npaj cov khoom tsis xwm txheej graphite
Qhov dawb paug ntawm graphite electrodes tseem siv rau kev ua rau ntau cov khoom siv graphite xws li crucibles, pwm, thiab cov khoom cua sov. Piv txwv li, hauv cov iav quartz kev lag luam, rau txhua 1 tuj ntawm hluav taws xob melting raj tsim, 10 tons ntawm daim ntawv qhia chaw nyob electrode electrode yog qhov yuav tsum tau; Rau txhua txhua 1 tuj ntawm quartz cib tsim, 100 kilo ntawm graphite electrode daim ntawv seem yog noj.
