Nzira yekudzivirira oxidation ye graphite electrodes panguva yekugadzira simbi.Graphite electrodes anoshandiswa mune arc metallurgy se conductive consumable zvinhu, uye mari yavo yekushandisa inokwana 10-15% yemutengo wemagetsi echoto kugadzira simbi.

Mumakore achangopfuura, kuitira kuvandudza kugadzirwa kwechoto chemagetsi uye kuderedza kushandiswa kwemagetsi, mavhiri emagetsi akagamuchira kushandiswa kwepamusoro-soro, uye kushandiswa kweoxidation ye electrode surfaces kunowedzera kuwedzera, nokudaro kuwedzera kuwedzera kushandiswa kwe electrode uye kunyungudutsa mari.Saka sei iwe oxidize iyo graphite electrode

Graphite electrode inogona kuchengetedzwa kubva kune oxidation nekuisa inodzivirira coating pamusoro peiyo electrode.Heano dzimwe nzira dzekudzivirira oxidation yegraphite electrodes:

1. Chekutanga, denderedzwa remigero isina kudzika inogadzirwa pamusoro peiyo graphite electrode, chinangwa ndechekuita kuti cermet layer inyatso kunamatira pamusoro peiyo graphite electrode, uye ipapo iyo graphite electrode inopisa kusvika 250 ℃ mukati. choto chinopisa, uye ipapo pfuti yesimbi inoshandiswa pa electrode.Pamusoro, pfapfaidza chidimbu chitete chealuminium, pfapfaidza imwe dhiri ye cermet slurry pane aruminiyamu layer, uye wobva washandisa kabhoni arc kunyudza, pfapfaidza slurry uye arc sinter, dzokorora 2-3 nguva kugadzira cermet Iyo layer ine. Ukobvu hwakakwana.

Iyo resistivity ye cermet ndeye 0.07-0.1pm, iyo yakaderera pane iyo yegraphite electrode.Pa 900 ℃ ye 50h, gasi haripindiki uye tembiricha yekunyungudika iri 1750-1800 ℃.The coating element composition haina mhedzisiro pasimbi yakanyungudutswa.Kuwedzera zvigadzirwa, magetsi uye basa rinoshandiswa mu anti-oxidation coating kuchawedzera mutengo wemagraphite electrode ne10%, asi iyo unit inoshandiswa yegraphite electrodes patani yesimbi yechoto yemagetsi inogona kuderedzwa ne20-30% (mhedzisiro. yekushandiswa pane zvakajairika magetsi emagetsi).Sezvo kupfeka kuri brittle material, cermet ibrittle material, saka dzivisa kudhumhana paunenge uchiishandisa, uye usaite kuti jasi ribve.

2. Kuderedza kusvibiswa kumhepo: Graphite electrodes inofanira kuchengetwa munzvimbo yakaoma uye isina mhepo kudzivirira kusvibiswa kune unyoro nemhepo.Izvi zvichabatsira kudzivirira oxidation.

3. Kudzikisa tembiricha yekushanda: Kushandisa electrode pane yakaderera tembiricha kunogona kuderedza mikana oxidation.Izvi zvinogona kuwanikwa nekudzikisa ikozvino kana kuwedzera electrode spacing.

4. Kushandisa gasi rinodzivirira: Gasi rinodzivirira rakadai seargon kana nitrogen rinogona kushandiswa panguva yekushanda kudzivirira oxidation.Iyo gasi inobatsira kugadzira mhepo yekudzivirira yakatenderedza electrode.

5. Kuchenesa kwakakodzera: Kucheneswa kwakakodzera kwe electrode kusati kwashanda kunogona kubvisa chero tsvina kana kusvibiswa kunogona kukonzera oxidation.

Kuwanda kwekushandisa: Inokodzera zvigadzirwa zvegraphite senge graphite electrodes, anode carbon blocks, electrolytic aluminium zvidyarwa, graphite molds, graphite crucibles, uye zvimwe zvigadzirwa zvegraphite pamusoro sealing anti-oxidation, kuvhara anti-corrosion, kurebesa hupenyu hwezvigadzirwa zvegraphite ne zvishoma 30%, kuwedzera simba rezvinhu.
