RP Graphite Electrode rau Ladle Rauv
Kev faib tawm ntawm Graphite Electrodes
Lub tshuab hluav taws xob arc steel ua rauv tuaj yeem muab faib ua lub tshuab hluav taws xob tsis tu ncua (kwv yees li 300KVA ib tuj), lub tshuab hluav taws xob muaj zog (kwv yees li 400kVA ib tuj) thiab lub tshuab hluav taws xob ultra-siab fais fab (500 ~ 1200KV / A ib tuj) raws li transformer muaj peev xwm ib tuj ntawm qhov cub muaj peev xwm.
Raws li kev faib tawm ntawm cov hluav taws xob hluav taws xob theem ntawm hluav taws xob hluav taws xob hluav taws xob ua hluav taws xob, thiab raws li qhov sib txawv ntawm cov khoom siv raw siv hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thiab tshuaj lom neeg ntawm cov electrode tiav, graphite electrode tau muab faib ua peb hom: tsis tu ncua fais fab graphite electrode (RP) , siab zog graphite electrode (HP) thiab ultra-siab zog graphite electrode (UHP).
Kev Taw Qhia ntawm RP Graphite Electrode
RP graphite electrode feem ntau yog ua los ntawm roj av coke ua raw cov ntaub ntawv thiab thee asphalt li binder los ntawm calcination, batching, kneading, molding, ci, graphitization thiab machining.
Graphite Electrode yog tus neeg xyuas pib uas tso tawm lub zog hluav taws xob hauv hluav taws xob arc rauv kom sov thiab yaj cov hlau seem.
Nta
RP graphite electrode yog tsim nrog roj av coke, nrog qis graphitization kub.nws muaj cov yam ntxwv hauv qab no:
1.High resistivity
2.Large linear expansion coefficient
3.Cov thermal poob siab tsis kam
4.Qhov tso cai tam sim no ceev yog tsawg
Daim ntawv thov ntawm RP Graphite Electrode
(1) Rau cov hlau ua hauv Electric Arc Rauv (EAF) thiab Ladle Rauv (LF)
RP Graphite electrode feem ntau yog siv hauv LF / EAF rau steel ua.Thaum graphite electrode ua haujlwm hauv LF, qhov tam sim no yuav raug qhia los ntawm graphite electrode rau hauv lub qhov cub, thiab yuav muaj qhov cua sov uas yog tsim los ntawm hluav taws xob arc ntawm electrode kawg thiab rauv nqi rau smelting.
(2) Kev tsim cov xim hlau silicon thiab daj phosphorus hauv submerged arc rauv
Qee cov pa roj carbon electrode nrog loj loj (piv txwv li.700mm-1400mm) yog siv los ua cov hlau silicon thiab daj phosphorus hauv submerged arc rauv.Qhov qis ntawm cov pa roj carbon electrode yog faus rau hauv tus nqi, tsim ib qho arc nyob rau hauv cov txheej txheem, cov khoom yuav smelted los ntawm lub tshav kub zog generated los ntawm cov kuj ntawm tus nqi.Piv txwv li, kwv yees li 100kg ntawm graphite electrode yog siv rau 1 tuj ntawm cov hlau silicon.
(3) Rau kev tsim corundum hauv hluav taws xob rauv
(4) Siv rau kev ua cov khoom tshwj xeeb zoo li graphite
Qhov khoob ntawm graphite electrode kuj yog siv los ua ntau yam tshwj xeeb zoo li graphite khoom
