High kuchena graphiteinoreva graphite ine kabhoni inodarika 99.99%.Yakakwirira kuchena graphite ine zvakanakira senge tembiricha kuramba, corrosion resistance, thermal shock resistance, low thermal expansion coefficient, self-lubrication, low resistance coefficient, uye easy mechanical processing.Kuita tsvakiridzo pamusoro pekugadzirwa kwepamusoro-kuchena graphite uye kuvandudza kunaka kwechigadzirwa kwakakosha zvakanyanya mukusimudzira indasitiri yeChina yakakwirira-kuchena graphite.
Kuti tisimudzire kusimukira kweindasitiri yeChina yepamusoro-soro yegraphite, kambani yedu yakaisa mari yakawanda yevashandi uye zviwanikwa mukutsvagisa nekuvandudza kwepamusoro-kuchena graphite, ichipa mipiro yakakosha mukuiswa kwepamusoro-kuchena graphite.Zvino regai ndikuudzei nezvetsvagiridzo nebudiriro yekambani yedu:
- General process kuyerera kwekugadzira yakakwirira-kuchena graphite:
Nzira huru yekugadzira ye-high-purity graphite inoratidzwa muMufananidzo 1. Zviri pachena kuti nzira yekugadzira ye-high-purity graphite yakasiyana neyo graphite electrodes.High kuchena graphite inoda structural isotropic mbishi zvinhu, izvo zvinoda kukuyiwa kuita hupfu hwakatsetseka.Isostatic pressing molding tekinoroji inoda kuiswa, uye kutenderera kwekugocha kwakareba.Kuti uwane density inodiwa, akawanda impregnation yekugocha ma cycles anodiwa, uye iyo graphitization cycle yakareba kupfuura yakajairwa graphite.
1.1 Raw zvinhu
Izvo zvigadzirwa zvekugadzira yakakwirira-kuchena graphite zvinosanganisira aggregates, binders, uye impregnating agents.Aggregates anowanzo gadzirwa netsono yakaita petroleum coke uye asphalt coke.Izvi zvinodaro nekuti tsono yakaumbwa nepetroleum coke ine hunhu hwakaita senge yakaderera madota (kazhinji isingasviki 1%), nyore graphitization pakupisa kwakanyanya, yakanaka conductivity uye thermal conductivity, uye yakaderera mutsara wekuwedzera coefficient;Iyo graphite inowanikwa nekushandisa asphalt coke pane imwechete graphitization tembiricha ine yakakwirira yemagetsi resistivity asi yakakwirira mechanical simba.Nokudaro, pakugadzira zvigadzirwa zve graphitized, kuwedzera kune petroleum coke, chikamu cheasphalt coke chinoshandiswawo kuvandudza simba remagetsi rechigadzirwa.Mabhainda anowanzo shandisa marasha tar pitch,inova chigadzirwa che distillation process yemarasha tara.Iyo itema yakasimba patembiricha yekamuri uye haina kunyungudika kwakadzikama.
1.2 Calcination/Kunatswa
Calcination inoreva kudziya kwepamusoro-kupisa kurapwa kweakasiyana akasimba kabhoni mbishi zvinhu pasi pemamiriro ekunze emhepo.Zvikamu zvakasarudzwa zvine madhigirii akasiyana ehunyoro, tsvina, kana zvinhu zvinoputika mukati mechimiro chazvo nekuda kwekusiyana kwekupisa kwekubikira kana geological age yekuumbwa kwemarasha.Izvi zvinhu zvinoda kubviswa pachine nguva, zvikasadaro zvinokanganisa kunaka kwechigadzirwa uye kuita.Nokudaro, zvikamu zvakasarudzwa zvinofanira kuverengerwa kana kucheneswa.
1.3 Kukuya
Zvinhu zvakasimba zvinoshandiswa kugadzirwa kwegraphite, kunyangwe saizi yebhuroko yakaderedzwa mushure mekuverengerwa kana kucheneswa, ichine hukuru hukuru hukuru nekuchinja kwakakosha uye kusaenzana kuumbwa.Naizvozvo, zvinodikanwa kupwanya aggregate particle size kuti isangane nezvinodiwa zvemukati.
1.4 Kusanganisa nekukanya
Hupfu hwepasi hunoda kusanganiswa necoal tar binder zvakaenzana usati waiswa mumushini wekukanyira unopisa wekukanya kuitira kuti zvinhu zvacho zviparadzirwe zvakafanana.
1.5 Kugadzira
Nzira huru dzinosanganisira extrusion molding, kuumba, vibration molding, uye isostatic kuumba kuumba
1.6 Kubika
Izvo zvakagadzirwa kabhoni zvigadzirwa zvinofanirwa kugochwa, izvo zvinosanganisira carbonizing iyo binder mubinder coke kuburikidza nekupisa kupisa (inenge 1000 ℃) pasi pemamiriro emhepo ari ega.
1.7 Kuiswa pamuviri
Chinangwa chekuisa pamuviri ndechekuzadza madiki mapores akaumbwa mukati mechigadzirwa panguva yekugocha neasphalt yakanyungudutswa uye mamwe maajenti ekuisa pamuviri, pamwe neapo akavhurika pores mune aggregate coke particles, kuvandudza vhoriyamu density, conductivity, mechanical simba, uye makemikari corrosion resistance yechigadzirwa.
1.8 Graphitization
Graphitization inoreva kudziya kwepamusoro-tembiricha yekurapa iyo inoshandura iyo thermodynamically isina kugadzikana isiri graphite kabhoni kuita graphite kabhoni kuburikidza nemafuta activation.
Kugamuchirwa kushanyira uye kuongorora fekitori yedu, inonyanya kuita magirafu molds, yakakwirira-kuchena graphite, graphite crucibles, nano graphite upfu, isostatic kudzvanya graphite, graphite electrodes, graphite tsvimbo, zvichingodaro.
