Dab tsi yog graphip electrode?
Graphitation electrode tsuas yog siv rau hluav taws xob arc rauv thiab submerged tshav kub thiab cov cua sov kuj ua tau tus neeg coj ua zoo. Hauv tus nqi ntawm hluav taws xob arc rauve steelmaking, kev noj ntawm graphite hluav taws xob cov account rau li 10%.
It is made of petroleum coke and pitch coke, and high-power and ultra-high-power grades are made of needle coke. Lawv muaj cov ntsiab lus tshauv tsawg, ua kom zoo nkauj hluav taws xob, cua sov, thiab corrosion tsis kam, thiab yuav tsis yaj lossis deform ntawm qhov kub.
Txog graphite electrode qib thiab diameters.
Jinsun muaj cov qhab nia sib txawv thiab cov diameters. Koj tuaj yeem xaiv los ntawm RP, HP lossis UHP cov qib, uas tuaj yeem pab koj txhim kho cov khoom siv hluav taws xob ua kom zoo, thiab nce cov txiaj ntsig kev lag luam. Peb muaj ntau qhov diameters, 150mm-700mm, uas tuaj yeem siv rau smelting operations ntawm hluav taws xob arc ntawm sib txawv tones.
Kev xaiv kho kom raug ntawm hom electrode thiab loj yog qhov tseem ceeb heev. Qhov no yuav ua lub luag haujlwm tseem ceeb hauv kev ua kom zoo ntawm cov hlau smelted thiab cov haujlwm ib txwm ua haujlwm ntawm cov hluav taws xob tshuab hluav taws xob.
Nws yuav ua haujlwm li cas hauv EAF steelmaking?
Graphite electrode tam sim no mus rau hauv steelmaking rauv, uas yog lub hluav taws xob arc rauvicmakaking txheej txheem. Qhov muaj zog tam sim no kis tau los ntawm cov cua sov hloov los ntawm cable rau tus tuav ntawm qhov kawg ntawm peb electrode caj npab thiab ntws mus rau hauv.
Yog li ntawd, nruab nrab ntawm cov electrode kawg thiab them tus nqi ARC tawm, thiab tus nqi pib yaj siv cov cua sov tsim los ntawm arc thiab tus nqi pib yaj. Raws li lub peev xwm ntawm cov hluav taws xob hluav taws xob, cov chaw tsim tshuaj yuav xaiv txawv diameters rau kev siv.
Txhawm rau siv cov electrodes txuas ntxiv thaum lub sijhawm smelting, peb txuas cov hluav taws xob los ntawm cov txiv ntoo thocples threed. Txij li cov txiv mis hla me dua li ntawm lub electrode, lub txiv mis yuav tsum muaj lub zog ntau dua thiab qis tiv taus ntau dua li cov electrode.
Ib qho ntxiv, muaj ntau qhov ntau thiab tsawg thiab qib, nyob ntawm lawv siv thiab cov kev cai tshwj xeeb ntawm cov txheej txheem EAF statmaking.
