400 UHP graphite electrode
Graphite electrodes inonyanya kushandiswa mukugadzira simbi. Iron scrap inonyungudutswa muchoto chemagetsi arc uye inodzokororwa. Semhando yekondakita, ivo chinhu chakakosha murudzi urwu rwe
UHP graphite electrode inonyanya kugadzirwa neyemhando yepamusoro tsono coke, uye inoshandiswa zvakanyanya mumagetsi emagetsi arc furnaces.Inokwanisa kutakura density iripo kupfuura 25A/cm2

Manufacturing process
Graphite electrode inonyanya kugadzirwa nepetroleum coke uye tsono coke, yakasanganiswa nemarasha mbichana, kupinda kuburikidza nemaitiro ekuverenga, kukanya, kuumba, kubheka, graphitizing uye machining, pakupedzisira kuve zvigadzirwa. Heano dzimwe tsananguro dzeimwe nzira yekugadzira:
Kukanya: Kukuchidzira nekusanganisa imwe kabhoni particles nehupfu nehumwe huwandu hwebhainda pane imwe tembiricha, kuita uku kunonzi kukanya.
Basa rekukanya
①Sanganisa marudzi ese ezvigadzirwa zvakaenzana, uye panguva imwe chete gadzira zvimedu zvekabhoni zvemhando dzakasiyana siyana sanganisa uye kuzadza, uye gadzirisa kusimba kwemusanganiswa;
②Mushure mekuwedzera marasha asphalt, tora zvinhu zvese zvakasimba pamwechete.
③Mamwe marasha emarasha anopinda mukati mezvivharo zvemukati, izvo zvinowedzera kuvandudza kuwanda uye kunamatira kwepaste.
Kugadzira: Iyo yakakanyiwa kabhoni paste inowedzeredzwa mumuviri wegirinhi (kana girinhi chigadzirwa) ine imwe chimiro, saizi, density uye simba mumudziyo wekuumba. Iyo paste ine deformation yepurasitiki pasi pesimba rekunze.
Kugocha kunonziwo kubikira, Kupisa kwekushisa kwakanyanya, kuchiita kuti marasha agadzirwe kabhoni kuti coke iumbwe, iyo inosanganisa iyo carbonaceous aggregates uye hupfu hwehupfu pamwe chete nehupamhi hwemagetsi simba, kushomeka kwekudzivirira, kugadzikana kwemafuta kuri nani uye kugadzikana kwemakemikari.
Sekondari kugocha ndeyekubika imwezve nguva, ichiita iyo inopinza pitch carbonized. Electrodes (marudzi ese kunze kweRP) uye minyatso inoda kuwanda kwepamusoro inodiwa kubikwa kechipiri, uye mazamu matatu-dip mana-bake kana maviri-dip matatu matatu.
