UHP Ultra-High Power Graphite Electrode Details
UHP (Ultra-High Power) graphite electrodes chinhu chakakosha conductive zvinhu mumaindasitiri emazuva ano esitarurgical, akagadzirirwa kutsungirira mitoro yakanyanyisa iripo. Iwo anonyanya kushandiswa mumagetsi arc furnace steelmaking uye yakakwirira-yekupedzisira alloy smelting, uye zvakanakira zvekushomeka kwesimba rekushandisa uye kugadzikana kwakanyanya kunoita kuti ive chinhu chakakosha chinodyiwa pakuvandudza maindasitiri.
I. Core Tsanangudzo uye Kuita Kwakanakira
-Core Positioning: Inokwanisa kumirisana nezvino densities pamusoro pe25 A/cm² (kusvika ku40 A/cm²), kuwana kunyungudika kwakanaka kuburikidza nepamusoro-tembiricha yemagetsi arcs inodarika 3000 ° C inogadzirwa pakati peiyo electrode tipi nechaji yevira. Iwo ndiwo musimboti wechikamu che Ultra-yakakwirira simba emagetsi arc furnaces (EAFs) uye kunatsa mavira.
-Makiyi Ekuita Paramita:
- Electrical Conductivity: Resistivity ≤ 6.2 μΩ·m (zvimwe zvigadzirwa zvepamusoro zvakaderera se 4.2 μΩ · m), zvakakwirira kudarika zvakajairika high-power (HP) electrodes;
-Mechanical Simba: Flexural simba ≥ 10 MPa (majoini anogona kusvika pamusoro pemakumi maviri MPa), anokwanisa kumirisana nekuchaja zvinokonzeresa uye emagetsi vibrations;
- Thermal Stability: Coefficient of thermal expansion chete 1.0-1.5 × 10⁻⁶/℃, isingatani kuputika kana kuparara pasi pekukurumidza kupisa uye kutonhora;
- Chemical Characteristics: Ash content ≤ 0.2%, density 1.64-1.76 g/cm³, oxidation yakasimba uye kushorwa kwemarara, zvichiita kuti kushandiswa kwakaderera patani yesimbi.
II. Core Production process uye Raw Materials
- Key Raw Materials: Kushandisa 100% yepamusoro petroleum-based tsono coke (kuvimbisa kuwedzera kwakaderera uye yakakwirira conductivity), yakasanganiswa neyakagadziridzwa yepakati-tembiricha pitch binder (kunyorovesa point 108-112 ° C) uye yakaderera quinoline insoluble (QI ≤ 0.5% impregnant). - Core Process: Iyo nzira inosanganisira ingredient kusanganisa uye kukanya → extrusion molding → calcination (kaviri) → high-pressure impregnation (kamwe chete kune electrode body, katatu kune yekubatanidza) → graphitization (in-line process inopfuura 2800 ℃) → mechanical processing. Kunyatso kudzora tembiricha uye parameter optimization inoita kuti chigadzirwa charongeka (kushivirira kwakatwasuka ± 10mm/50m) uye kugadzikana kwekuita.
- Process Innovation: Iyo yakagadziridzwa "imwe impregnation, maviri calcination" maitiro anopfupisa kutenderera kwekugadzira nemazuva gumi nemashanu-30 zvichienzaniswa nemaitiro echinyakare, kuderedza mutengo neanosvika mazana maviri RMB / toni, uku ichichengetedza yakanakisa kupisa kwekuvhunduka kuramba.
III. Main Application Scenarios
- Inotungamira Munda: AC/DC ultra-high power electric arc furnace steelmaking, inoshandiswa mukugadzirwa kwesimbi yepamusoro-soro uye simbi yakakosha, kuvandudza kunyunguduka kwepamusoro nepamusoro pe30% uye kuderedza kushandiswa kwesimba ne15% -20%;
- Yakawedzerwa Zvishandiso: Kunyungudutswa kwezvinhu zvepamusoro-soro senge silicon yeindasitiri, ferrosilicon, uye yero phosphorous mumidziyo yearc yakanyungudika, pamwe nekugadzirwa kwezvinhu zvinopisa zvakanyanya senge corundum uye abrasives, zvinochinjika kune zvakasiyana-siyana zvemagetsi emagetsi (diameter 12-28 inches, ikozvino inotakura 000-1200000 A2000).
IV. Indasitiri Kukosha uye Mafambiro Ekusimudzira
-Kukosha Kwakakosha: Kutyaira shanduko yemagetsi arc simbi yekugadzira simbi yakanangana ne "kukurumidza, kuchena, uye kwakanyanya kushanda" maitiro, chinhu chakakosha chekuchengetedza simba uye kudzikisira kuburitsa muindasitiri yesimbi uye kubata nekabhoni tariff. Chikamu chayo chemusika chinotarisirwa kudarika 60% yehuwandu hwegraphite electrode inodiwa ne2025, nemutengo unosvika zviuru gumi nezvisere RMB/ton;
-Tekinoroji Direction: Kutarisa pane graphene coating modification (kuderedza kusangana kuramba ne40%), silicon carbide composite kusimbiswa, hungwaru kugadzira (digital twin process simulation), uye hupfumi hwedenderedzwa (guruva kudzoreredza mwero 99.9% + marara kupisa kupora), kuti uwedzere kuvandudza hupenyu uye hushamwari kwezvakatipoteredza.
