Tan iyo 2018, awoodda wax soo saarka graphite electrode ee Shiinaha ayaa si weyn u kordhay.Sida laga soo xigtay xogta Baichuan Yingfu, awoodda wax soo saarka qaranku waxay ahayd 1.167 milyan tan 2016, iyadoo heerka isticmaalka awoodda uu hooseeyo 43.63%.In 2017, awoodda wax soo saarka ee graphite ee Shiinaha ayaa gaadhay ugu yaraan 1.095 milyan oo tan, ka dibna la hagaajinta barwaaqada warshadaha, awoodda wax soo saarka ayaa sii wadi doona in la dhigo 2021. Awoodda Shiinaha ee graphite electrode soo saarka ahaa 1.759 million tons, ilaa 61% ka. 2017. 2021, ka faa'iidaysiga awoodda warshadaha waa 53%.Sannadka 2018, heerka ugu sarreeya ee isticmaalka awoodda ee warshadaha graphite electrode wuxuu gaaray 61.68%, ka dibna wuxuu sii waday inuu hoos u dhaco.Ka faa'iidaysiga awoodda 2021 waxaa la filayaa inay noqoto 53%.Awooda warshadaha ee graphite electrode waxa inta badan lagu qaybiyaa waqooyiga Shiinaha iyo waqooyi bari Shiinaha.2021, awoodda wax-soo-saarka graphite electrode ee Waqooyiga iyo waqooyi-bari Shiinaha waxay xisaabin doontaa in ka badan 60%.Laga bilaabo 2017 ilaa 2021, awoodda wax soo saarka ee "2+26" graphite electrode magaalada waxay noqon doontaa mid deggan 400,000 ilaa 460,000 tan.
Laga bilaabo 2022 ilaa 2023, awoodda korantada garaafyada cusub way yaraan doontaa.Sannadka 2022, awoodda ayaa la filayaa inay noqoto 120,000 oo tan, iyo 2023, awoodda cusub ee korantada garaafyada ayaa la filayaa inay noqoto 270,000 oo tan.Haddii qaybtan ka mid ah awoodda wax soo saarka la gelin karo shaqada mustaqbalka waxay weli ku xiran tahay faa'iidada suuqa elektiroonigga ah ee graphite iyo kormeerka dawladda ee warshadaha isticmaalka tamarta sare, waxaa jira hubaal la'aan.
Electrode graphite waxaa iska leh isticmaalka tamarta sare, warshadaha sii daayo carbon sare.Sii daynta kaarboon halkii ton ee korantada graphite waa 4.48 tan, taas oo kaliya ka liidata birta silikoon iyo aluminium elektrolytic ah.Iyada oo ku saleysan qiimaha kaarboonka ee 58 yuan/ton Janaayo 10, 2022, qiimaha qiiqa kaarboonku wuxuu xisaabiyaa 1.4% qiimaha korantada garaafyada sare ee korontada.Isticmaalka korantada halkii ton ee korantada graphite waa 6000 KWH.Haddii qiimaha korontada lagu xisaabiyo 0.5 yuan/KWH, kharashka korantadu wuxuu xisaabiyaa 16% qiimaha graphite electrode.
Marka loo eego asalka "laba xakameynta" isticmaalka tamarta, heerka hawlgalka ee birta eAF ee hoose ee leh korantada garaafyada ayaa si weyn loo xannibay.Laga soo bilaabo Juun 2021, heerka shaqada ee 71 meheradaha birta eAF waxay joogeen heerkii ugu hooseeyay ku dhawaad saddex sano, iyo baahida korantada garaafyada si weyn ayaa loo xakameeyay.
Korodhka soo-saarka korantada garaafyada ee dibedda iyo saadka iyo faraqa baahida ayaa inta badan loogu talagalay korantada ultra-sare ee garaafyada.Marka loo eego xogta Frost & Sullivan, wax soo saarka graphite electrode ee wadamada kale ee adduunka ayaa hoos uga dhacay 804,900 tan sanadkii 2014 ilaa 713,100 tan sanadka 2019, kaas oo wax soo saarka ultra-high power graphite electrode uu ahaa qiyaastii 90%.Tan iyo 2017, kororka sahayda graphite electrode iyo farqiga baahida dalalka dibadda inta badan ka timaadda ultra-sare korontada graphite electrode, taas oo ay sababtay koritaanka fiiqan ee foornada korontada dibadda wax soo saarka steel cayriin ka 2017 si ay u 2018. In 2020, wax soo saarka dibadda ee Birta foornada korontada ayaa hoos u dhacday arrimo faafa awgeed.Sannadka 2019, dhoofinta saafiga ah ee Shiinaha ee graphite electrode ayaa gaadhay 396,300 tan.2020, oo uu saameeyay cudurka faafa, wax soo saarka birta foornada korontada ee dibedda ayaa si aad ah hoos ugu dhacday 396 milyan oo tan, hoos u dhac 4.39% sannadkii, iyo dhoofinta saafiga ah ee Shiinaha ee graphite electrode ayaa hoos ugu dhacday 333,900 tan, hoos u dhac 15.76% sannadkii.
