UHP Graphite Electrode with Nipples
1. Kupu Whakataki:
UHP graphite electrodewhakamahia mo te hangarua maitai i roto i te ahumahi oumu pewa hiko.Ko tana waahanga matua ko te tiihi ngira utu nui, he mea hanga mai i te hinu, i te tar waro ranei.Ka mahia te hiko kauwhata ki te hanga porotakaroa, ka mahia he waahi miro ki ia pito.I tenei ara, ka taea te whakahiato i te electrode graphite ki roto i te pou hiko ma te whakamahi i te hononga hiko.
Hei whakatutuki i nga whakaritenga o te pai ake o te mahi me te iti o te utu katoa, kei te piki haere te rongonui o te oumu hiko ultra-high power arc.Na reira, ko nga electrodes kauwhata UHP me te diameter neke atu i te 500 mm ka rangatira te maakete
2. Nga ahuatanga
- Te ātete teitei o nāianei me te tere o te tukunga.
- He pai te pumau o te ahua me te kore e ngawari ki te whakarereke.
- Te ātete ki te pakaru me te pakaru.
- Te kaha o te waiariki me te waiariki o te wiri.
- Te kaha o te miihini me te iti o te aukati.
- Te tino tika o te miihini me te pai o te whakaoti mata.
- Ko te hanganga rite, te pai o te kawe me te waiariki
3. Taupānga
Kei te whakamahia nuitia te electrode graphite i roto i tehanga o te koranu maitai, whakarewa me etahi atu mea kore-whakarewa.
Te oumu arc hiko DC.
Umu arc AC.
Umu pewa kua rukuhia.
Umu whao.
(1) te hiko hiko kauwhata hiko
Ka whakaaetia ki te whakamahi i te hiko kauwhata me te kiato o naianei kei raro iho i te 17a / cm2, e whakamahia ana i roto i nga oumu hiko hiko noa mo te hanga maitai, te whakarewa silicon, te whakarewa ūkuikui kowhai, me era atu.
(2) Oxidation ātete pani hiko kauwhata
Ko te hiko kauwhata kua whakakikoruatia ki te paparanga o te paparanga whakamarumaru antioxidant (graphite electrode antioxidant).Hangaia he paparanga whakamarumaru ka taea te whakahaere i te hiko me te aukati i te waikura teitei-te wera, te whakaiti i te kohi hiko i te wa e hanga ana te maitai (19% ~ 50%), te roa o te oranga o te hiko (22% ~ 60%), me te whakaiti i te kohi hiko hiko. o te hiko.Ko te rongonui me te whakamahi i tenei hangarau ka taea te kawe mai i nga paanga ohaoha me te hapori:
① He iti ake te kohinga o te hiko kauwhata, a ka heke te utu whakaputa ki tetahi waahanga.Hei tauira, i roto i te tipu hanga maitai, i runga i te kohi o te 35pcs graphite electrodes ia wiki me te 165 oumu para i roto i te tuatahi LF te parakore oumu kahore katinga puta noa i te tau, 373pcs graphite electrodes e taea te ora ia tau i muri i te graphite electrode oxidation resistance hangarau he. whāngai
(153 tons) electrode, tatau i te 3000USD ia ton o ultra-high power electrode ia tau, USD 459,000 ka taea te penapena.
② He iti ake te hiko o te graphite electrode, ka penapena i te kohinga hiko hanga maitai, ka penapena te utu whakaputa me te penapena hiko!
③ Na te mea he iti ake te whakarereketanga o te electrode graphite, ka heke te nui o te mahi me te whakarea morearea o nga kaiwhakahaere, me te pai ake o te whakaputa.
④ He iti te kai me te iti o te hua parahanga.I tenei ra, i te wa e tautokohia ana te tiaki hiko, te whakahekenga tukunga me te whakamarumaru i te taiao, he tino hiranga hapori.
Ko tenei hangarau kei roto tonu i te rangahau me te whakawhanaketanga i Haina, a kua timata ano etahi o nga kaihanga o roto ki te whakaputa.Kua whakamahia nuitia i Hapani me etahi atu whenua whakawhanake.I tenei wa, kei reira ano nga kamupene whai mana ki te kawemai i tenei paninga whakamarumaru anti-oxidation ki Haina.
(3) High power graphite electrode.Ko te hiko kauwhata me te kiato o naianei o 18 ~ 25A / cm2 ka whakaaetia kia whakamahia, e whakamahia ana i roto i te oumu hiko hiko teitei mo te hanga maitai.
(4)Ultra high power graphite electrode.UHP Graphite electrodes ki te kiato o nāianei nui ake i te 25A / cm2 e whakaaetia.Kei te nuinga whakamahia te reira mo te ultra-tiketike mana steelmaking oumu pewa hiko.
