Mugraphite electrodeyekugadzira simbi kana anode paste yealuminium uye magnesium kugadzira (kunyunguduka electrode), kuitira kuti petroleum coke (coke) isangane nezvinodiwa, iyo coke inoverengerwa.Calcination tembiricha, petroleum coke volatiles vanoonekwa zvinhu.

(1) Bvisa hunyoro uye zvinhu zvinoputika kubva kune zvigadzirwa

Iyo inoshatisa yemukati yezvinhu zvakasvibirira inogona kubviswa necalcination, nekudaro ichiwedzera iyo yakagadziriswa kabhoni yemukati yezvinhu mbishi.Iyo mvura iri mumidziyo inobviswa ne calcination, iyo inobatsira kupwanya, kuongorora uye kukuya mashandiro, kunatsiridza kuita kweadsorption yekabhoni raw materials kune binder, uye kunatsiridza mhando yezvigadzirwa.

(2) Kuvandudza kuwanda uye kusimba kwemagetsi ezvigadzirwa

Mushure mekuverengerwa, iyo kabhoni zvinhu inoderera muhuwandu, inowedzera density uye simba nekuda kwekubviswa kwezvinoputika, uye inowana zvirinani kugadzikana kwemafuta, nekudaro ichidzikisa chechipiri shrinkage yezvigadzirwa panguva yecalcination.

(3) Kuvandudza conductivity yezvinhu zvakasvibiswa

Mushure mekuverenga, mavhuvhu anobviswa, uye chimiro chemolecular chinoshandukawo, kuderedza resistivity yemagetsi uye nekuvandudza magetsi ekugadzirisa zvinhu.Kazhinji kutaura, iyo yakakwirira dhigirii yecalcination, zviri nani conductivity ye calcined zvinhu.

(4) Kuvandudza oxidation kuramba kwezvinhu zvakabikwa

Mushure mekuverengera, sezvo tembiricha yekabhoni raw materials inokwira, tsvina yakaita sehydrogen, okisijeni nesarufa inoburitswa zvakatevedzana kuburikidza nepyrolysis uye polymerization process, uye chiitiko chemakemikari chinodzikira uye hunhu hwemuviri nemakemikari huchagadzikana, nekudaro kuvandudza oxidation. kushorwa kwezvinhu zvakabikwa.

Calcined char inonyanya kushandiswa mukugadzirwa kwegraphite electrode, carbon paste products, carborundum, giredhi rekudya phosphorus industry, metallurgical industry uye calcium carbide, pakati peiyo graphite electrode ndiyo inonyanya kushandiswa.Uye coke isina kupfuta kupisa inogona zvakare kushandiswa zvakananga kune calcium carbide sechinhu chikuru, kugadzirwa kwesilicon carbide uye boron carbide sezviyo zvekukuya, asiwo yekukanda maitiro ane dense coke uye zvimwe zvinhu.
