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

Cov hluav taws xob graphite yog cov khoom siv cua sov uas siv rau hauv cov cub tawg hluav taws xob los ua hlau los ntawm cov khoom seem, cov tsheb qub thiab lwm yam khoom siv. Cov hluav taws xob muab cua sov rau cov hlau seem kom yaj nws los tsim cov hlau tshiab. Cov cub tawg hluav taws xob arc siv dav hauv kev lag luam hlau thiab txhuas vim tias lawv pheej yig rau kev tsim khoom. Cov hluav taws xob graphite tuaj yeem sib sau ua ke rau hauv cov thooj voos kheej kheej vim tias lawv yog ib feem ntawm lub hau hluav taws xob. Thaum lub zog hluav taws xob muab los ntawm cov hluav taws xob graphite no, lub zog hluav taws xob arc muaj zog tsim, yaj cov hlau seem. Raws li qhov xav tau cua sov thiab qhov loj ntawm lub cub tawg hluav taws xob, cov hluav taws xob sib txawv tuaj yeem siv. Yuav kom tsim tau 1 tuj hlau, kwv yees li 3 kg ntawm graphite electrodes yog qhov yuav tsum tau ua. Hauv kev tsim hlau, graphite muaj peev xwm tiv taus qhov kub siab heev, yog li qhov kub ntawm lub taub hau hluav taws xob ncav cuag li 3000 degrees Celsius. Koob thiab roj av coke yog cov khoom siv raw tseem ceeb siv los ua cov hluav taws xob graphite. Nws siv sijhawm rau lub hlis los ua cov hluav taws xob graphite, thiab tom qab ntawd qee cov txheej txheem, suav nrog kev ci thiab rov ci, siv los hloov cov coke mus rau hauv graphite. Cov hluav taws xob graphite yooj yim dua los tsim dua li cov hluav taws xob tooj liab, thiab qhov ceev ntawm kev tsim khoom sai dua vim tias nws tsis xav tau cov txheej txheem ntxiv xws li kev sib tsoo tes.
Kev tsim kho kev lag luam graphite electrode, qhov kev thov hlau ntau ntxiv hauv kev lag luam roj thiab roj thiab tsheb yuav txhawb kev txhim kho ntawm kev lag luam graphite electrode. Ntau tshaj 50% ntawm cov hlau thoob ntiaj teb tsim tawm yog siv rau hauv kev lag luam kev tsim kho thiab kev tsim kho vaj tse. Daim ntawv tshaj tawm suav nrog cov tsav tsheb, kev txwv, cov cib fim, thiab cov qauv tshiab uas tau pab txhawb rau kev loj hlob ntawm kev lag luam thaum lub sijhawm tshuaj xyuas. Daim ntawv tshaj tawm tshuaj xyuas cov hom thiab cov ntawv thov ntawm kev faib cheeb tsam.
Graphite electrode yog ib qho ntawm cov conductors, thiab nws yog ib feem tseem ceeb ntawm cov txheej txheem steelmaking. Hauv cov txheej txheem no, cov hlau seem raug yaj hauv lub cub tawg hluav taws xob thiab rov ua dua tshiab. Lub graphite electrode hauv lub cub tawg tau yaj cov hlau. Graphite muaj cov thermal conductivity siab, thiab nws yog cua sov thiab kev cuam tshuam zoo heev. Nws muaj kev tiv thaiv qis, uas txhais tau tias nws tuaj yeem ua cov dej ntws loj uas xav tau los yaj hlau. Graphite electrode feem ntau yog siv hauv lub cub tawg hluav taws xob (EAF) thiab lub cub tawg ladle (LF) rau kev tsim hlau, ferroalloy, silicon hlau graphite electrode yog siv hauv lub cub tawg hluav taws xob (EAF) thiab lub cub tawg ladle (LF) rau kev tsim hlau, ferroalloy tsim, silicon hlau Tsim thiab smelting txheej txheem.
Daim ntawv tshaj tawm txog kev lag luam graphite electrode thoob ntiaj teb suav nrog cov neeg ua si paub zoo xws li GrafTech, Fangda Carbon Tuam Tshoj, SGL Carbon Lub Tebchaws Yelemees, Showa Denko, Graphite Is Nrias teb, HEG Is Nrias teb, Tokai Carbon Nyiv, Nippon Carbon Nyiv, SEC Carbon Nyiv, thiab lwm yam. American GrafTech, Fangda Carbon Tuam Tshoj thiab Graphite Is Nrias teb muaj peev xwm tsim khoom tag nrho ntawm 454,000 tons.
