UHP Graphite Electrode ya EAF/LF
Mbali
1.Resistivity ndi yotsika, kulola kachulukidwe kakang'ono kamakono
2.Smaller linear extension coefficient
3.Kupambana kwamphamvu kwa kutentha kwa kutentha.
4.Kuyendetsa bwino kwamagetsi
5.Kukana kutentha kwakukulu ndi kukhazikika bwino
6.Kukhazikika kwamankhwala abwino
ntchito
(1) Pakupanga zitsulo mu EAF/LF
Graphite electrode imagwiritsidwa ntchito makamaka mu ng'anjo ya Electric arc posungunula zitsulo.Pamene graphite elekitirodi ntchito EAF, 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
