Graphite electrodesyog cov khoom tseem ceeb hauv kev ua haujlwm ntawm arc furnaces, ua lub luag haujlwm tseem ceeb hauv ntau cov txheej txheem kev lag luam.
1. Taw qhia rau Graphite Electrodes:
Graphite electrodes yog cov khoom siv hluav taws xob ua los ntawm cov khoom siv graphite.Lawv ua haujlwm raws li cov khoom siv hluav taws xob tam sim no hauv hluav taws xob arc rauv, qhov chaw uas lawv raug rau qhov kub thiab txias.Vim lawv muaj peev xwm tiv taus qhov kub thiab txias thiab tiv thaiv cov tshuaj tua kab mob, graphite electrodes tau dhau los ua cov cuab yeej tseem ceeb hauv ntau daim ntawv thov kev lag luam.
2. Kev sib xyaw thiab cov qauv:
Graphite electrodes feem ntau yog tsim los ntawm roj av coke, koob coke, thiab thee tar pitch.Petroleum coke ua raws li cov khoom siv tseem ceeb, muab cov pa roj carbon rau cov electrodes.Koob coke, uas muaj cov thermal conductivity thiab tsis tshua muaj thermal expansion zog, yog siv los txhim kho cov electrodes 's mechanical zog thiab hluav taws xob conductivity.Thaum kawg, thee tar pitch ua haujlwm ua tus neeg sawv cev khi uas tuav cov khoom sib xyaw ua ke thaum lub sijhawm tsim khoom, ua kom cov khoom siv hluav taws xob muaj kev ncaj ncees.
3.Graphite Electrode Manufacturing Txheej txheem:
Kev tsim cov graphite electrodes suav nrog ntau theem, pib nrog kev xaiv thiab crushing ntawm raw cov ntaub ntawv.Tom qab ntawd cov ntaub ntawv sib xyaw thiab sib xyaw kom ua tiav qhov xav tau muaj pes tsawg leeg.Tom qab sib tov, lub resulting sib tov yog molded rau hauv cylindrical duab los ntawm nias los yog extruding txheej txheem.Cov molded electrodes yog ces rhuab nyob rau hauv ci rauv kom tshem tawm cov volatile Cheebtsam thiab txhim kho lawv ceev.Thaum kawg, cov electrodes ci tau dhau los ua cov txheej txheem graphitization uas lawv tau sov kom sov siab tshaj 2500 degrees Celsius los txhim kho lawv cov hluav taws xob conductivity.
Graphite electrodes muaj ntau yam khoom tseem ceeb uas ua rau lawv zoo heev rau lawv daim ntawv thov.Lawv cov hluav taws xob hluav taws xob siab ua kom muaj txiaj ntsig zoo tsim hluav taws xob nyob rau hauv arc rauv, tso cai rau kev ua kom zoo tshaj plaws thiab ua kom zoo.Tsis tas li ntawd, graphite electrodes pom zoo thermal poob siab tsis kam, ua rau lawv tiv taus qhov kub thiab txias hloov tsis tau tawg.Lawv cov tshuaj inertness thiab yaig tsis kam ua rau lawv muaj peev xwm tiv taus cov xwm txheej hnyav thiab tshuaj lom neeg muaj nyob hauv arc furnaces.
5. Kev siv:
Graphite electrodes pom cov ntawv thov hauv ntau yam kev lag luam, feem ntau hauv kev lag luam steelmaking.Lawv siv nyob rau hauv hluav taws xob arc rauv rau steel thiab alloy ntau lawm, qhov twg lawv yaj hlau seem thiab hloov mus rau hauv usable steel.Graphite electrodes kuj siv nyob rau hauv ladle furnaces los refine steel thiab kho nws muaj pes tsawg leeg.Tsis tas li ntawd, cov electrodes no ua lub luag haujlwm tseem ceeb hauv kev tsim cov silicon, phosphorous, thiab calcium carbide, nrog rau hauv electrolysis ntawm ntau yam hlau.
6. Hom Graphite Electrodes:
Graphite electrodes tuaj nyob rau hauv ntau qhov ntau thiab tsawg thiab qib kom haum raws li kev lag luam sib txawv.Ultra-siab zog (UHP) graphite electrodesyog tsim los rau high-power arc furnaces thiab loj-scale steel ntau lawm.Lub zog siab (HP) graphite electrodes yog tsim rau cov hlau ntau lawm, thaum lub zog tsis tu ncua (RP) graphite electrodes feem ntau yog siv rau hauv cov hluav taws xob arc me me thiab hauv cov cub tawg nrog qis zog.
7. Qhov tseem ceeb hauv Chaw Tsim Khoom:
Graphite electrodes yog cov khoom tseem ceeb hauv kev lag luam steel, vim tias lawv pab tsim cov hlau zoo hauv tus nqi tsim nyog thiab siv tau zoo.Lawv siv nyob rau hauv arc furnaces tso cai rau kev rov ua dua ntawm cov hlau seem thiab txo kev siv zog.Tsis tas li ntawd, graphite electrodes pab txhawb kev ruaj ntseg ntawm steel ntau lawm los ntawm kev txo cov pa roj carbon monoxide emissions thiab txo cov pov tseg pov tseg.
Graphite electrodes yog cov khoom tseem ceeb hauv arc rauv, ua kom muaj cov txheej txheem xws li steel ntau lawm thiab hlau refining.Lawv cov khoom tseem ceeb, xws li hluav taws xob siab, thermal shock resistance, thiab yaig kuj, ua rau lawv zoo heev rau cov kev thov no.Lub luag haujlwm ntawm arc rauvgraphite electrode manufacturersNws yog ib qho tseem ceeb los xyuas kom meej cov khoom ntawm cov khoom siv hluav taws xob zoo uas ua tau raws li cov kev cai tshwj xeeb ntawm kev lag luam sib txawv.Raws li kev lag luam hlau txuas ntxiv mus ntxiv, kev tshawb fawb thiab kev tsim kho hauv graphite electrode manufacturing yuav pab txhawb kev nce qib ntxiv thiab kev ruaj khov hauv cov txheej txheem kev lag luam.
