"Kev lag luam thoob ntiaj teb graphite electrode tau muaj nuj nqis ntawm 9.13 billion US las hauv 2018 thiab xav tias yuav ncav cuag 16.48 billion US las los ntawm 2025, nrog rau kev loj hlob txhua xyoo ntawm 8.78% thaum lub sijhawm kwv yees."
Nrog kev nce siab hauv kev tsim cov hlau thiab kev lag luam ntawm cov khoom siv niaj hnub no, qhov kev thov rau engineering thiab kev tsim kho cov ntaub ntawv tseem nce ntxiv, uas yog qee yam tseem ceeb uas ua rau kev loj hlob ntawm lub ntiaj teb graphite electrode kev lag luam.

Graphite electrodes yog cov khoom siv cua sov siv nyob rau hauv hluav taws xob arc rauv los ua hlau los ntawm seem, tsheb qub thiab lwm yam khoom siv.Cov electrodes muab cua sov rau cov seem hlau kom yaj nws los tsim cov hlau tshiab.Hluav taws xob arc rauv yog siv dav hauv steel thiab aluminium ntau lawm kev lag luam vim lawv pheej yig los tsim.Graphite electrodes tuaj yeem sib sau ua ke rau hauv lub tog raj kheej vim tias lawv yog ib feem ntawm lub tshuab hluav taws xob npog.Thaum cov khoom siv hluav taws xob tau dhau los ntawm cov graphite electrodes, muaj zog hluav taws xob arc tsim, melting cov seem hlau.Raws li qhov xav tau ntawm cov cua sov thiab qhov loj ntawm lub cub hluav taws xob, cov electrodes sib txawv tuaj yeem siv tau.Yuav kom tsim tau 1 tuj hlau, kwv yees li 3 kg ntawm graphite electrodes yuav tsum tau.Hauv kev tsim cov hlau, graphite muaj peev xwm tiv taus qhov kub thiab txias, yog li qhov kub ntawm cov hlau electrode nce mus txog 3000 degrees Celsius.Koob thiab roj av coke yog cov khoom siv tseem ceeb siv los ua graphite electrodes.Nws siv sijhawm rau lub hlis los ua cov graphite electrodes, thiab tom qab ntawd qee cov txheej txheem, suav nrog kev ci thiab rov ua dua, yog siv los hloov cov coke rau hauv graphite.Graphite electrodes yooj yim dua rau kev tsim dua li tooj liab electrodes, thiab kev tsim khoom nrawm dua vim nws tsis tas yuav muaj cov txheej txheem ntxiv xws li kev sib tsoo phau ntawv.
Kev tsim kho ntawm graphite electrode kev lag luam, kev xav tau ntau ntxiv rau cov hlau hauv cov roj thiab roj thiab kev lag luam tsheb yuav tsum txhawb kev tsim kho ntawm graphite electrode kev lag luam.Ntau tshaj 50% ntawm lub ntiaj teb steel tsim yog siv nyob rau hauv kev tsim kho thiab infrastructure industries.Daim ntawv tshaj tawm suav nrog cov tsav tsheb, kev txwv, cov hauv kev, thiab cov kev hloov pauv tsis ntev los no uas tau ua rau kev loj hlob ntawm kev lag luam thaum lub sijhawm tshuaj xyuas.Daim ntawv tshaj tawm txheeb xyuas cov ncauj lus kom ntxaws txog hom thiab kev siv hauv cheeb tsam segmentation.
Graphite electrode yog ib qho ntawm cov conductors, thiab nws yog ib qho tseem ceeb ntawm cov txheej txheem steelmaking.Nyob rau hauv cov txheej txheem no, seem hlau yog melted nyob rau hauv hluav taws xob arc rauv thiab recycled.Lub graphite electrode nyob rau hauv lub cub tawg ua tau melted hlau.Graphite muaj thermal conductivity, thiab yog kub heev thiab cuam tshuam resistant.Nws muaj qhov tsis muaj zog, uas txhais tau hais tias nws tuaj yeem ua cov dej ntws loj uas yuav tsum tau yaj hlau.Graphite electrode feem ntau yog siv rau hauv hluav taws xob arc rauv (EAF) thiab ladle furnace (LF) rau steel ntau lawm, ferroalloy, silicon hlau graphite electrode yog siv nyob rau hauv hluav taws xob arc rauv (EAF) thiab ladle furnace (LF) rau steel ntau lawm, ferroalloy ntau lawm, silicon hlau Ntau lawm thiab smelting txheej txheem
Daim ntawv tshaj tawm thoob ntiaj teb graphite electrode kev lag luam npog cov neeg paub zoo xws li GrafTech, Fangda Carbon Tuam Tshoj, SGL Carbon Lub Tebchaws Yelemees, Showa Denko, Graphite India, HEG India, Tokai Carbon Nyiv, Nippon Carbon Nyiv, SEC Carbon Nyiv, thiab lwm yam American GrafTech, Fangda Carbon Tuam Tshoj thiab Graphite Is Nrias teb muaj tag nrho cov peev txheej ntawm 454,000 tons.
