Nzira yekudzora sei kugona kwekabhoni kwesimbi yakanyungudutswa ne graphitized petroleum coke kuti uwane kunyungudutswa kwekabhoni kunoshanda uye kushoma?

Kudzora Kwakarurama Kwekukwanisa Kwekabhoni Musimbi Yakanyungudutswa uye Kubudirira Kwekugadzira Simbi Inoshanda Isina Kabhoni Yakawanda: Nzira Dzehunyanzvi

I. Kusarudzwa Kwezvinhu Zvisina Kugadzirwa: High-Purity Graphitized Petroleum Coke sehwaro

Kudzora Chiratidzo Chepakati

  • Kabhoni Yakagadzika ≥ 98%: Pakuwedzera kwega kwega kwe1% kwekuchena, simba rezvikamu zvakakandwa rinokwira ne15%, huwandu hwezvikafu zvinodzikira ne8%, uye kushandiswa kwesimba rekunyungudutsa kunoderedzwa zvakananga.
  • Sarufa ≤ 0.03%: Kupfuura miganhu yesarufa ne0.02% kunogona kukonzera kuwedzera kwe40% kwekuboora kwemabhuroko emasilinda einjini, zvichiita kuti coke ine sarufa shoma iongororwe zvakanyanya (semuenzaniso, coke yekuSouth Africa ine sarufa ≤ 0.3%).
  • Nitrogen ≤ 150 ppm, Dota ≤ 0.5%: Nitrogen yakawandisa inokanganisa graphite morphology mu ductile iron, nepo dota rakawanda richiumba slag inclusions, zvichikanganisa mashandiro esimbi.

Kusimbiswa kweZvivakwa

  • Kuedzwa kweMetallic Luster: Zvigadzirwa zvechokwadi zvinoratidza nzvimbo dzakapwanyika dzakaita segirazi, nepo mhando dzisina kunaka dzichiita sedzakasharara, zvichiratidza kusimba kwekristaro.
  • Kuongorora Saizi yeLaser Particle:
    • Zvidimbu zve 1–3 mm zvekushandisa pakukanda nemazvo (mwero wekunyungudika unoenderana nekumhanya kwekuyerera kwesimbi yakanyungudutswa).
    • Zvidimbu zve3–5 mm zvekugadzira simbi yemagetsi (EAF) (zvinononotsa kurasikirwa kweoxidation).
    • Hupfu hunopfuura 3% hunoumba chigadziko chinodzivisa kunyudzwa kwekabhoni.

II. Kugadzirisa Maitiro: Kugadzira Graphitization Yekupisa Kwakanyanya uye Kudyisa Kwakangwara

Tekinoroji yekudzimisa kupisa kwakanyanya ye3000°C

  • Kugadziriswazve kweAtomu yeKabhoni: Mumaovheni eAcheson akavharwa, mablock ecoke anorapwa kwemaawa makumi manomwe nemaviri pa ≥3000°C, zvichigadzira maumbirwo ekristalline emuchindwe. Masara esulfur anodonha kusvika pa ≤0.03%, nekabhoni yakagadzika inodarika 98%.
  • Kudzora Kushandiswa Kwesimba: Tani imwe neimwe yechigadzirwa inoshandisa 8,000 kWh, magetsi achikonzera >60% yemari. Kugadzirisa tembiricha yechoto (semuenzaniso, kuchengetedza ≥2800°C) kunoderedza kushandiswa kwesimba reyuniti.

Sisitimu Yekudya Yakangwara

  • Kutarisa Kwenguva Yechokwadi kwe5G+AI: Masensa anoteedzera hunhu hwemagetsi esimbi, pamwe chete nemamodheru ekufanotaura akaenzana nekabhoni kuti averenge zvakananga mwero wekuwedzera carburizer.
  • Kudyisa Ruoko rweRobotic Grading:
    • Zvidimbu zvakakora (3–5 mm) kuti zvirambe zvichishanda kwenguva refu.
    • Upfu hwakatsetseka (<1 mm) hwekugadzirisa kabhoni nekukurumidza, zvichideredza kurasikirwa kweoxidation.

III. Kubatanidzwa kweTekinoroji dzeSimbi Dzisina Kabhoni Yakawanda

Kugadzirwa kweEAF Green

  • Kudzoreredza Kupisa Kwemarara: Inoshandisa gasi rinopisa zvakanyanya kugadzira magetsi, kuchengetedza simba uye kuderedza CO₂ kuburitswa nenzira isina kunanga.
  • Kutsiva Coke: Inotsiva chikamu checoke ne graphitized petroleum coke carburizers, zvichideredza kushandiswa kwemafuta efossil asingadzokororwe.
  • Kupisa Zvimedu: Kunopfupisa kutenderera kwekunyungudutsa, kunoderedza kushandiswa kwesimba, uye kunoenderana nemaitiro e "near-zero carbon" EAF.

Kubatana kweSimbi Yakavakirwa paHydrogen

  • Kupinza Hydrogen muBlast Furnace: Magasi anoputika ane hydrogen yakawanda (semuenzaniso, H₂, gasi rechisikigo) anotsiva chikamu checoke, achideredza kuburitswa kwecarbon.
  • Kuderedza Hydrogen Shaft Furnace: Inoshandisa hydrogen sechinhu chinoderedza kusvibiswa kwesimbi zvakananga, ichideredza kusvibiswa kwemhepo ne >60% zvichienzaniswa nemidziyo yemazuva ano yekuputika.

IV. Kudzora Hunhu: Kutevedza Kwakazara uye Kuongorora

Kutevedza Kushandiswa Kwezvinhu Zvisina Kugadzirwa
Kuskena maQR code kunoita kuti munhu awane ruzivo rwezvemitero, mavhidhiyo ekuyedza sarufa, uye data rekugadzirwa kwezvinhu, zvichiita kuti zvive pachena kuti zvinodiwa.

Kuongorora Maikorosikopu yeElectron
Vanoongorora hunhu hwezvinhu vanogadzirisa huwandu hwemakristalline kuburikidza ne electron microscopy, vachibvisa silica-alumina inclusions kudzivirira tsaona muzvinhu zvakagadzirwa nesimbi yepamusoro senge simbi yenyukireya.

V. Maitiro Ekushandisa uye Mabhenefiti

Kukanda Kwepamusoro-soro

  • Simbi yeVaruvhu yeNyukireya: Kudzvinyirirwa kwesarufa kunovhara huwandu huri pasi pe0.015%, zvichidzivirira ngura yekumanikidzwa mumamiriro ekupisa kwakanyanya/kumanikidzwa.
  • Zvivharo zveInjini dzeMoto: Zvinoderedza mwero wekukuvara kubva pa15% kusvika pa3% uye zvinoderedza zvakanyanya kukora kwevhu.

Kugadzirwa kweSimbi Yakakosha

  • Simbi Yemuchadenga Yakasimba: Kuwedzera zvidimbu zve 1–3 mm zvakarongwa kunoita kuti pave nekusvika 97% yekunyudzwa kwekabhoni, zvichibvisa kupwanyika kwesimbi ye 42CrMo uye kuwedzera goho pamusoro pe 99%.

Mashandisirwo Esimba Idzva

  • Mabhatiri eLithium-Ion Anodes: Anogadzirwa kuita zvidimbu zvakagadziriswa zve12 μm, zvichiwedzera simba remagetsi kupfuura 350 Wh/kg.
  • Vagadziri veNuclear Reactor Neutron: Kusiyana kwega kwega kwe1% kuchena mumagiredhi epamusoro-kuchena kunokonzera kushanduka-shanduka kwe10% muhuwandu hwekunyudzwa kweneutron.
