UHP Ultra-High Power Graphite Electrode Details
Li-electrode tsa graphite tsa UHP (Ultra-High Power) ke lisebelisoa tsa mantlha tse sebetsang indastering ea sejoale-joale ea metallurgic, e etselitsoeng ho mamella meroalo e feteletseng ea hajoale. Haholo-holo li sebelisoa ho etsa tšepe ea tšepe ea arc le ho qhibilihisa alloy e phahameng ea ho qetela, 'me melemo ea bona ea tšebeliso e tlaase ea matla le botsitso bo phahameng li etsa hore e be ntho e ka sehloohong e ka sebelisoang bakeng sa ntlafatso ea indasteri.
I. Tlhaloso ea Motheo le Melemo ea Ts'ebetso
- Core Positioning: E khona ho mamella density tsa hajoale kaholimo ho 25 A/cm² (ho fihla ho 40 A/cm²), e khona ho qhibiliha ka mokhoa o nepahetseng ka li-arcs tsa mocheso tse phahameng tse fetang 3000 ° C tse hlahisitsoeng lipakeng tsa ntlha ea elektrode le tefiso ea sebōpi. Ke karolo ea mantlha ea libono tsa motlakase tsa motlakase tse phahameng haholo (EAFs) le libopi tse hloekisang.
- Liparamente tsa Ts'ebetso ea Bohlokoa:
- Motlakase Conductivity: Resistivity ≤ 6.2 μΩ·m (lihlahisoa tse ling tse phahameng tse tlaase ho 4.2 μΩ·m), li phahametse li-electrode tse tloaelehileng tsa matla a phahameng (HP);
- Matla a Mechini: Matla a Flexural ≥ 10 MPa (manonyeletso a ka fihla ho 20 MPa), a khona ho mamella tšusumetso ea ho tjhaja le ho thothomela ha motlakase;
- Thermal Stability: Coefficient ea ho atolosoa ha mocheso feela 1.0-1.5 × 10⁻⁶/℃, e sa tloaelehang ho phunyeha kapa ho senya tlas'a mocheso o potlakileng le o pholileng;
- Litšobotsi tsa Lik'hemik'hale: Likahare tsa molora ≤ 0.2%, boima ba 1.64-1.76 g / cm³, oxidation e matla le ho hanyetsa ha kutu, ho fella ka tšebeliso e tlaase ka lithane tsa tšepe.
II. Mokhoa oa Tlhahiso ea Core le Lisebelisoa tse Raw
- Lisebelisoa tsa Raw tsa Bohlokoa: Ho sebelisa 100% ea boleng bo phahameng ba nale e entsoeng ka petroleum coke (ho netefatsa katoloso e tlaase le conductivity e phahameng), ho kopantsoe le ho feto-fetoha ha mocheso oa mocheso oa mocheso oa mocheso oa mocheso oa mocheso (ntlha e bonolo 108-112 ° C) le quinoline e tlaase e sa qhibilihisitsoeng (QI ≤ 0.5%). - Ts'ebetso ea mantlha: Ts'ebetso e kenyelletsa motsoako oa motsoako le ho luba → ho bopa ha extrusion → calcination (habeli) → ho kenella ka khatello e matla (hanngoe bakeng sa 'mele oa elektrode, makhetlo a mararo bakeng sa sehokelo) → graphitization (mokhoa oa mohala o fetang 2800 ℃) → ts'ebetso ea mochini. Taolo e nepahetseng ea mocheso le ho ntlafatsa paramente ho netefatsa ho nepahala ha sehlahisoa (ho mamella ho otloloha ± 10mm / 50m) le botsitso ba ts'ebetso.
- Ts'ebetso ea Ts'ebetso: Ts'ebetso e ntlafalitsoeng ea "impregnation e le 'ngoe, calcination e' meli" e khutsufatsa potoloho ea tlhahiso ka matsatsi a 15-30 ha e bapisoa le mekhoa ea setso, e fokotsa litšenyehelo ka hoo e ka bang 2000 RMB/ton, ha e ntse e boloka ts'ebetso e ntle ea mocheso oa mocheso.
III. Maemo a mantlha a Kopo
- Tšimo e ka Sehloohong: AC / DC ultra-high power arc arc steelmaking steelmaking, e sebelisoang ho hlahisa tšepe ea boleng bo phahameng ba alloy le tšepe e khethehileng, ho ntlafatsa ts'ebetso ea ho qhibiliha ka ho feta 30% le ho fokotsa tšebeliso ea matla ka 15% -20%;
- Likopo tse Atolositsoeng: Ho qhibiliha ha lisebelisoa tse phahameng tse kang silicon ea indasteri, ferrosilicon, le phosphorus e mosehla ka har'a libono tsa arc tse ka tlas'a metsi, hammoho le tlhahiso ea lihlahisoa tse phahameng tsa mocheso tse kang corundum le li-abrasives, tse lumellanang le litlhaloso tse fapaneng tsa libōpi tsa motlakase (bophara ba 12-28 inch, hona joale ho jara bokhoni ba 20000-20000 2000).
IV. Boleng ba Indasteri le Mekhoa ea Ntlafatso
- Boleng ba Bohlokoa: Ho tsamaisa phetoho ea tšepe ea arc ea motlakase ho ea lits'ebetsong tse "potlako, tse hloekileng, le tse sebetsang hantle", ke sesebelisoa sa bohlokoa bakeng sa ho boloka matla le ho fokotsa tlhahiso indastering ea tšepe le ho sebetsana le litefiso tsa khabone. Kabelo ea eona ea 'maraka e lebelletsoe ho feta 60% ea kakaretso ea tlhoko ea li-electrode tsa graphite ka 2025, ka theko e ka bang 18,000 RMB/ton;
- Tataiso ea Theknoloji: Ho shebana le phetoho ea ho roala graphene (ho fokotsa khanyetso ea ho ikopanya ka 40%), silicon carbide composite reinfosite, tlhahiso e bohlale (digital twin process simulation), le moruo oa selikalikoe (sekhahla sa ho hlaphoheloa ha lerole 99.9% + litšila tsa ho hlaphoheloa ha mocheso), ho ntlafatsa nako ea bophelo le botsoalle ba tikoloho.
