Graphite electrode chinhu chakakosha chepamusoro-tembiricha conductive zvinhu zvemagetsi choto simbi. Simba remagetsi rinoiswa muchoto chemagetsi kuburikidza ne graphite electrode, uye tembiricha yakakwira inogadzirwa nearc pakati pekuguma kwe electrode uye kuchaja inoshandiswa senzvimbo yekupisa kunyungudutsa mutero wekugadzira simbi. Tsanangudzo dzinobva pa300 kusvika ku800mm muhupamhi uye 1.8m, 2.1m, 2.4m, uye 2.7m pakureba.

Nzira yekugadzira ndeye calcine petroleum coke pa1350 ° C. Iyo inokonzeresa calcined coke inopwanyika, ivhu uye yakavhenekwa kuti iite aggregate uye hupfu hunodiwa pakuumbwa. Iyo tsono coke uye hupfu inogadziriswa uchishandisa yakakosha tekinoroji fomula yekuumba. Iyo calcined coke inosanganiswa neakasiyana particle saizi, zviyero zvakasiyana uye imwe chikamu chebinder asphalt mukneader zvinoenderana nekumwe kupisa uye nguva.

Mushure mekukanya, iyo kabhoni paste inotumirwa kukamuri yemidziyo yemuchina wekuumba kuburikidza nebhandi rekutakura, uye rinoiswa nemidziyo yekuumba. Plastic deformation inoitika pasi pesimba rekunze, pakupedzisira ichigadzira electrode green body (kana green product) ine imwe chimiro, saizi, density uye simba. Chigadzirwa chegirini chinoiswa muchoto chakanyatsogadzirirwa kupisa kupisa kwekupisa kwe1300 ° C kuti carbonize marasha emarasha mumuviri wakasvibira kuti agadzire chigadzirwa chine simba remagetsi repamusoro, resistivity yakaderera, kugadzikana kwemafuta kuri nani uye kugadzikana kwemakemikari.

Kune zvigadzirwa zvekabhoni, kugocha ndeimwe yenzira huru mukugadzirwa kwekabhoni zvigadzirwa. Iyo yekugocha yekugadzira kutenderera kwakareba (22-30 mazuva ekutanga kugochwa, 5-20 mazuva echipiri kugocha zvichienderana nechoto chemoto), uye kushandiswa kwesimba kwakakwira. Mushure meizvozvo, iyo kabhoni inoiswa mumudziyo wekumanikidza, uye iyo yemvura inobata agent asphalt inonyudzwa uye ichipinda mukati me electrode pores yechigadzirwa pasi pemamiriro e360-400 ° C uye 1.5-1.8MPa kudzvanywa kwekuwedzera vhoriyamu density. uye mechanical simba rechigadzirwa, uye kuvandudza conductivity uye conductivity yechigadzirwa. Thermal conductivity.

Mushure mekunge chigadzirwa chakagochwa chaiswa, chinogochwa zvakare kuti carbonize pitch yakanyudzwa mumapores echigadzirwa chakagochwa. Wobva wawedzera svikiro rekudzivirira kune chigadzirwa chakagochwa muchoto chemagetsi chepamusoro-soro chekupisa kabhoni chigadzirwa kusvika pamusoro pe2800 ° C, kushandura iyo amorphous turbostratic kabhoni kuita matatu-dimensional akaraira graphite crystal chimiro kuti uvandudze conductivity yemagetsi, thermal conductivity, uye kupisa kupisa kweiyo kabhoni zvinhu. Vibration kuita uye kugadzikana kwemakemikari kunoita kuti kabhoni zvinhu zvizora uye anti-kupfeka, uye kuburitsa tsvina kuvandudza kuchena kweiyo kabhoni zvinhu. Chekupedzisira, isu tinovimba nekucheka kugadzirwa kuti tiwane saizi inodiwa, chimiro, chaiyo, nezvimwe, uye kugadzira iyo electrode body inosangana nezvinodiwa zvekushandisa.
Nekuti majoini e electrode anoda kuwanda kwemuviri uye kushomeka kushomeka, maitiro ekugadzirisa anoda dip matatu uye mafiritsi mana kuti asangane nezvinodiwa.
Zvigadzirwa zvekambani yedu zvinoenderana neYB/T4088-2015, YB/T4089-2015, YB/T4090-2015 zviyero. Ma graphite electrodes nemajoini anogadzirwa ane high volume density, high flexural strength, low resistivity, good thermal shock resistance, uye Iine oxidizing zvivakwa zvakasimba uye inodarika mwero yenyika neindasitiri. Ichi chigadzirwa chapfuura kuongororwa kweNational Graphite Chigadzirwa Hunhu Hwekutarisa uye Yekuongorora Center.
