RP grafit éléktroda pikeun Ladle tungku
Klasifikasi éléktroda grafit
Listrik arc steel tungku nyieun bisa dibagi kana tungku listrik kakuatan biasa (ngeunaan 300KVA per ton),-daya tinggi tungku listrik (ngeunaan 400kVA per ton) jeung ultra-daya-daya tungku listrik (500 ~ 1200KV / A per ton) nurutkeun kana. kapasitas trafo per ton kapasitas tungku.
Numutkeun klasifikasi tingkat kakuatan listrik tina tungku listrik pembuatan baja, sarta nurutkeun béda bahan baku dipaké dina produksi éléktroda jeung indexes fisik jeung kimia éléktroda rengse, éléktroda grafit dibagi kana tilu variétas: éléktroda grafit biasa (RP) , éléktroda grafit kakuatan tinggi (HP) jeung éléktroda grafit kakuatan ultra-tinggi (UHP).
Bubuka RP grafit éléktroda
RP grafit éléktroda utamana dijieunna tina coke minyak bumi salaku bahan baku sarta aspal batubara salaku map ngaliwatan calcination, batching, kneading, molding, baking, graphitization na machining.
Éléktroda grafit nyaéta konduktor anu ngaluarkeun énérgi listrik dina tungku busur listrik pikeun ngamanaskeun sareng ngalebur besi tua.
Fitur
RP grafit éléktroda dihasilkeun ku coke minyak bumi, kalawan suhu graphitization low.éta ngagaduhan fitur di handap ieu:
1.Resistivitas tinggi
2.Large liniér ékspansi koefisien
3.Poor lalawanan shock termal
4.The allowable dénsitas ayeuna low
Aplikasi RP Graphite Electrode
(1) Pikeun pembuatan baja di Electric Arc Furnace (EAF) jeung Ladle Furnace (LF)
RP grafit éléktroda utamana dipaké dina LF / EAF pikeun pembuatan baja.Nalika éléktroda grafit berpungsi dina LF, arus bakal diwanohkeun ku éléktroda grafit kana tungku, sarta bakal aya sumber panas nu dihasilkeun ku busur listrik antara tungtung éléktroda jeung muatan tungku pikeun smelting.
(2) Pikeun ngahasilkeun silikon logam jeung fosfor konéng dina tungku arc submerged
Sababaraha éléktroda karbon kalayan ukuran badag (misalna 700mm-1400mm) dipaké pikeun ngahasilkeun silikon logam jeung fosfor konéng dina tungku arc submerged.Bagian handap éléktroda karbon dikubur dina muatan, ngabentuk busur dina lapisan muatan, bahan bakal smelted ku énergi panas dihasilkeun ku résistansi muatan.Contona, ngeunaan 100kg éléktroda grafit dikonsumsi pikeun 1 ton silikon logam.
(3) Pikeun ngahasilkeun korundum dina tungku listrik
(4) Dipaké pikeun ngolah produk grafit husus ngawangun
Kosong éléktroda grafit ogé dipaké pikeun ngolah rupa-rupa prod grafit husus ngawangun
