UHP Ultra-High Power Graphite Electrode Taipitopito
UHP (Ultra-High Power) electrodes graphite he rauemi kawe matua i roto i nga ahumahi whakarewa hou, i hangaia ki te tu atu i nga taumahatanga o naianei. Ko te nuinga o enei ka whakamahia i roto i te hanga rino oumu pewa hiko me te whakarewa koranu teitei, a ko o raatau painga o te iti o te whakapau kaha me te pumau nui ka waiho hei kai nui mo te whakapai ake i nga umanga.
I. Whakamaramatanga Matua me nga Painga Mahinga
- Turanga Matua: He kaha ki te tu atu i nga kiato o naianei i runga ake i te 25 A/cm² (tae atu ki te 40 A/cm²), ka tutuki pai te whakarewatanga ma nga pewa hiko teitei-nui atu i te 3000°C i hangaia i waenga i te pito hiko me te utu oumu. He waahanga matua o nga oumu arc hiko (EAF) me nga oumu para.
- Tawhā Mahinga Matua:
- Te Hiko Hiko: Te aukati ≤ 6.2 μΩ·m (etahi hua teitei te iti o te 4.2 μΩ·m), he pai ake i nga hiko hiko teitei (HP) noa;
- Te Kaha Miihini: Te kaha whakaheke ≥ 10 MPa (ka eke nga hononga ki runga ake i te 20 MPa), ka kaha ki te tu atu i nga whiunga me nga wiri hiko;
- Pumau Ngaaahu: Ko te whakarea o te roha waiariki 1.0-1.5 anake × 10⁻⁶/℃, karekau e pakaru, ka pakaru ranei i raro i te whakamahana tere me te whakamatao;
- Nga Ahuatanga Matū: Ko te ihirangi pungarehu ≤ 0.2%, te kiato 1.64-1.76 g/cm³, te kaha o te waikura me te aukati waikura, ka iti ake te kai mo ia ton o te maitai.
II. Tukatuka Hanganga Matua me nga Rawa Rawa
- Rauemi Raw Matua: Ma te whakamahi i te 100% teitei-kounga-kounga-koihini ngira ngira (whakaritea iti roha me te kawe teitei), ngā ki te whakarerekētia reo-mahana pitch here (waahi ngohengohe 108-112°C) me te iti quinoline insoluble (QI ≤ 0.5%) impregnating agent. - Tukatuka Matua: Ko te tukanga ko te whakauru me te pokepoke i te whakauru → extrusion molding → calcination (rua) → teitei-pressure impregnation (kotahi mo te tinana electrode, e toru nga wa mo te hono) → graphitization (i roto i te-raina tukanga i runga i te 2800 ℃) → tukatuka miihini. Ko te mana o te pāmahana tika me te arotautanga tawhā ka whakarite i te tika o te hua (te tika ± 10mm/50m) me te pumau o nga mahi.
- Whakahoutanga Tukanga: Ko te tikanga "kotahi impregnation, e rua calcination" ka whakapoto i te huringa whakaputa ma te 15-30 ra ka whakatauritea ki nga tikanga tuku iho, ka whakaheke i nga utu tata ki te 2000 RMB/ton, i te wa e mau tonu ana te pai o te awangawanga waiariki.
III. Nga Tauari Taupānga Matua
- Arahi Arahi: AC / DC ultra-high power arc arc furnace steelmaking, whakamahia i roto i te hanga o te kounga teitei koranu maitai me te maitai motuhake, te whakapai ake smelting tōtika e neke atu i te 30% me te whakaiti i te kohi pūngao e 15% -20%;
- Te Whakanuia Nga tono: Te whakarewa i nga taonga teitei penei i te silicon ahumahi, te ferrosilicon, me te ūkuikui kowhai i roto i nga oumu arc kua rukuhia, me te hanga o nga hua wera-nui penei i te corundum me te abrasives, ka taea te urutau ki nga korero rereke o nga oumu hiko (diameter 12-28 inihi, te kaha kawe o naianei).
IV. Te Uara Ahumahi me nga Tikanga Whakawhanaketanga
- Uara Matua: Ko te taraiwa i te hurihanga o te hanga rino oumu pewa hiko ki nga tikanga "tere, maamaa, me te pai ake", he rauemi matua mo te penapena hiko me te whakaheke i te tukunga i roto i te umanga rino me te aro ki nga utu waro. Ko tana wahanga maakete e tika ana kia neke atu i te 60% o te katoa o nga tono hiko kauwhata i te tau 2025, me te utu tata ki te 18,000 RMB/ton;
- Te Arahanga Hangarau: Te aro ki te whakarerekētanga whakakikorua o te graphene (whakaiti i te parenga whakapā ma te 40%), te whakakaha hiato hiato silicon carbide, te hanga mohio (whakarite tukanga mahanga mamati), me te ohanga porohita (te reiti whakaora puehu 99.9%+ te whakaora wera para), hei whakapai ake i te roanga o te oranga me te pai o te taiao.
