Kazhinji, busbar iri pakati pemagumo emagetsi eDC graphitization furnace rectifier cabinet ne conductive electrode ye furnace head inonzi short net, uye busbar inoshandiswa mu graphitization furnace inowanzova rectangular. Busbar ye graphitization furnace yakagadzirwa nemhangura nearuminiyamu. Copper ine simba guru remakanika, conductivity yemagetsi yakanaka uye inodzivirira ngura zvakanyanya. Aruminiyamu haina conductive zvakanyanya, asi aruminiyamu yakachipa uye ine huremu hwakareruka.
Tafura 3-2 Data rekushanda kwakakodzera kwemhangura nearuminiyamu
| 材 料 | 比重 | 极限强度(MPa) | 电阻率(µΩm) | 电阻的温度系数(1/℃） |

Sezvo kuramba kwechoto che graphitization furnace kuri kudiki, kunyanya padanho rekupedzisira rekutumira simba, kuramba kwechoto kunova kudiki, uye kuderera kwekumanikidzwa kwe short net kunowedzerwa, zvichikonzera kuwedzera kwekurasikirwa kwesimba. Saka, kana graphitization furnace ichigona kushanda zvakachengeteka uye zvine mwero zvine hukama hwepedyo nehunhu hwe short net.
Nheyo huru ndeyekuderedza kuvharwa kwemumbure mupfupi uye kuchengetedza mumbure mupfupi wese nekuderedzwa kudiki kwekumanikidzwa. Kune ma contacts akasiyana-siyana mu short mesh ye graphitization furnace. Kana paine contact pakati pe conductive electrode ne copper bus, contact pakati pe copper soft bus ne aluminum bus, contact pakati pe aluminum bus, nezvimwewo, ma contacts aya achagadzira contact resistance, zvichikanganisa hunhu hwe short net yese. Contact resistance ye conductor ine connection point haingotsamiri pamhando yezvinhu chete, asiwo pa contact area uye contact pressure panguva ye contact connection. Nekuda kwechikonzero ichi, chinonyanya kukosha pakubatanidza busbars ndechekuti: polishing yacho yakasimba.
Tafura 3-3 Kusagona kubata graphite ye1cm2 uye simbi ye1cm2
