Cov khoom lag luam twg yog suav nrog hauv graphite electrode cov khoom lag luam

Cov khoom lag luam electrode feem ntau suav nrog cov hluav taws xob graphite rau cov hluav taws xob me me, ferroalloys, thiab calcium carbide hauv ore cua sov rauv.

Graphite hluav taws xob suav nrog cov hluav taws xob ib txwm graphite hluav taws xob thiab muaj zog ntau thiab ultra-siab graphite electrodes. Kev tsim khoom ntawm lub zog hluav taws xob zoo li hluav taws xob graphite hluav taws xob tuaj yeem siv cov roj av zoo ua cov khoom siv. Yog tias lub zog dav dav, ib qho me me ntawm asphalt Coke yuav tsum tau muab ntxiv los txhim kho cov tshuab ua kom muaj zog ntawm electrode. Asphalt Coke tsis siv Txawv Tebchaws, tab sis siab softening poinhalt yog siv los ua phau ntawv. Txhawm rau tsim cov hluav taws xob siab electrodes thiab ultra-siab cugraphite electrodes, koob CEAKE yuav tsum tau siv cov khoom siv graphite nrog cov nqi qis dua thiab qis dua kev nthuav dav. Rau cov ntaub ntawv raw ntawm cov ntaub ntawv steelmakaking, cov ntsiab lus ntawm cov leej faj thiab phosphorus yuav tsum tau tswj hwm. Sulphur thiab phosphorus yuav ua rau cov hlau los ua pov thawj ob qho kub thiab txias brittleness.

Cov tshuaj pab hluav taws xob cov roj hluav taws xob feem ntau yog tsim los ntawm cov tshuaj lom neeg thiab cov khoom siv raw me me, qee zaum nrog cov ntxaij me me, thiab qee zaum nrog qee qhov ntau ntawm cov roj av coke ntxiv.

Ntuj graphite cov hluav taws xob yog tsim los ntawm cov duab graphite li cov khoom siv raw, thiab cov khoom lag luam tsis tau txais kev kho siab kub-kub. Hom hluav taws xob muaj hluav taws xob tiv thaiv hluav taws xob siab, qis dua tshuab zog, thiab muaj zog tawg thaum siv thaum siv.

Regenerated graphite electrodes tsim los ntawm kev sib tsoo cov khib nyiab lossis pov tseg graphite hluav taws xob ua tiav nrog graphite electrodes. Lawv muaj hluav taws xob resistivity, txom nyem thermal ruaj khov, muaj cov ntaub ntawv raw khoom, thiab tsis haum rau kev tsim cov elects-sized electrodes.

Lub electrode muab tshuaj txhuam ntawm tus kheej ci electrode yog ua los ntawm anthracite thee thiab metallurgical coke raws li cov khoom raw. Txhawm rau txo cov hluav taws xob tiv taus thiab txhim kho kev ua tau zoo, cov duab kos duab kos duab lossis cov duab ntuj raug muab ntxiv. Rau siab-xaus thawj zaug thiab theem nrab electrode pastes, hluav taws xob calcined anthracite (ib nrab graphitized) yuav tsum tau siv ua cov khoom siv raw. Xav txog yam xws li cov ntaub ntawv raw, hluav taws xob noj, thiab cov khoom tiv thaiv ib puag ncig ntawm cov muab tshuaj txhuam thiab anode paste yog ob qho tib si maj mam ntsuas tawm cov khoom lag luam
