RP Graphite Electrode yeLadle Furnace
Iyo Classification yeGraphite Electrodes
Magetsi arc simbi inogadzira choto inogona kupatsanurwa kuita yenguva dzose simba remagetsi (inenge 300KVA patani), yakakwirira-simba remagetsi choto (inenge 400kVA patani) uye yekupedzisira-yepamusoro-simba remagetsi (500 ~ 1200KV/A patani) zvichienderana ne Transformer huwandu patani yevira rehuni.
Zvinoenderana neiyo kupatsanurwa kwesimba remagetsi chiyero chemagetsi echoto chekugadzira simbi, uye zvinoenderana nekusiyana kwezvinhu zvinoshandiswa mukugadzira electrode uye emuviri uye kemikari indexes yeakapedzwa electrode, graphite electrode yakakamurwa kuita mhando nhatu: yenguva dzose simba graphite electrode (RP) , high power graphite electrode (HP) uye ultra-high simba graphite electrode (UHP).
Kutanga kweRP Graphite Electrode
RP graphite electrode inonyanya kugadzirwa nepetroleum coke seyakagadzirwa uye marasha asphalt sebhainda kuburikidza necalcination, batching, kukanya, kuumba, kubika, graphitization uye machining.
Graphite Electrode iconductor inoburitsa simba remagetsi muchoto chemagetsi arc kupisa nekunyungudusa zvimedu zvesimbi.
Features
RP graphite electrode inogadzirwa nepetroleum coke, ine yakaderera graphitization tembiricha.ine zvinhu zvinotevera:
1.High resistivity
2.Large linear yekuwedzera coefficient
3.Poor thermal shock resistance
4.Iyo inobvumirwa ikozvino density yakaderera
Iko Kushandiswa kweRP Graphite Electrode
(1) Yekugadzira simbi muMagetsi Arc Furnace (EAF) uye Ladle Furnace (LF)
RP Graphite electrode inonyanya kushandiswa muLF / EAF pakugadzira simbi.Kana graphite electrode iri kushanda muLF, ikozvino ichaunzwa negraphite electrode muchoto, uye pachave nekupisa sosi iyo inogadzirwa nemagetsi arc pakati peelectrode end nechoto chaji yekunyungudutsa.
(2) Yekugadzira simbi yesilicon uye yero phosphorous mune yakanyura arc choto
Imwe kabhoni electrode ine saizi hombe (eg.700mm-1400mm) inoshandiswa kugadzira simbi nesilicon uye yero phosphorous mu yakadzika arc choto.Chikamu chezasi checarbon electrode chakavigwa muchaji, chinoumba arc muchikamu chechaji, zvinhu zvichanyungudutswa nesimba rekupisa rinogadzirwa nekupokana kwechaji.Semuenzaniso, inenge 100kg ye graphite electrode inopedzwa kwe 1 toni yesimbi yesilicon.
(3)Kugadzira corundum muvira remagetsi
(4)Inoshandiswa kugadzira zvigadzirwa zvemagraphite akasarudzika
Iyo isina chinhu yegraphite electrode inoshandiswawo kugadzirisa akasiyana akasarudzika-akaumbwa graphite prod
