RP Graphite Electrode ya Ladle Furnace
Gulu la Graphite Electrodes
Ng'anjo yamagetsi yamagetsi yamagetsi imatha kugawidwa kukhala ng'anjo yamagetsi yanthawi zonse (pafupifupi 300KVA pa tani), ng'anjo yamagetsi yamphamvu kwambiri (pafupifupi 400kVA pa tani) ndi ng'anjo yamagetsi yamphamvu kwambiri (500 ~ 1200KV / A pa tani) molingana ndi thiransifoma mphamvu pa tani mphamvu ng'anjo.
Malinga ndi gulu la mphamvu yamagetsi yamagetsi opanga zitsulo zamagetsi, komanso kutengera kusiyanasiyana kwa zida zomwe zimagwiritsidwa ntchito popanga ma elekitirodi ndi ma index akuthupi ndi amankhwala a electrode yomalizidwa, ma elekitirodi a graphite amagawidwa m'mitundu itatu: graphite electrode (RP) , high power graphite electrode (HP) ndi Ultra-high power graphite electrode (UHP).
Kuyamba kwa RP Graphite Electrode
RP graphite elekitirodi makamaka opangidwa ndi mafuta coke monga zopangira ndi malasha asphalt monga binder kudzera calcination, batching, kneading, akamaumba, kuphika, graphitization ndi Machining.
Graphite Electrode ndi kondakitala amene amatulutsa mphamvu yamagetsi mu ng'anjo yamagetsi yamagetsi kuti itenthe ndi kusungunula zidutswa zachitsulo.
Mawonekedwe
RP graphite elekitirodi amapangidwa ndi petroleum coke, ndi otsika graphitization kutentha.ili ndi izi:
1. High resistivity
2.Large linear extension coefficient
3.Poor matenthedwe kugwedezeka kwamphamvu
4.Kuchuluka kwamakono kovomerezeka ndi kochepa
Kugwiritsa ntchito RP Graphite Electrode
(1) Pakupanga zitsulo mu Electric Arc Furnace (EAF) ndi Ladle Furnace (LF)
RP Graphite elekitirodi zimagwiritsa ntchito LF/EAF kupanga zitsulo.Pamene graphite elekitirodi ntchito LF, panopa adzakhala anayambitsa ndi graphite elekitirodi mu ng'anjo, ndipo padzakhala kutentha gwero amene kwaiye ndi arc magetsi pakati electrode mapeto ndi ng'anjo mlandu smelting.
(2) Kupanga zitsulo zachitsulo ndi phosphorous yachikasu mu ng'anjo ya arc yomira
Ena mpweya elekitirodi ndi kukula lalikulu (eg.700mm-1400mm) ntchito popanga zitsulo pakachitsulo ndi chikasu phosphorous mu mivi arc ng'anjo.Mbali yapansi ya carbon electrode imayikidwa m'manda, imapanga arc muzitsulo zosanjikiza, zinthuzo zidzasungunuka ndi mphamvu ya kutentha yomwe imapangidwa ndi kukana kwa malipiro.Mwachitsanzo, pafupifupi 100kg ya electrode ya graphite imadyedwa pa tani imodzi ya silicon yachitsulo.
(3) Popanga corundum mu ng'anjo yamagetsi
(4) Amagwiritsidwa ntchito pokonza zinthu zapadera zooneka ngati graphite
Ma electrode opanda graphite amagwiritsidwanso ntchito popanga ma graphite opangidwa ndi mawonekedwe apadera
