Kazhinji, bhazi riri pakati pekubuda kunopera kweDC graphitization furnace rectifier kabati uye conductive electrode yemusoro wechoto inonzi mambure mapfupi, uye bhazi rinoshandiswa muchoto chegraphitization rinowanzo rectangular. Iyo bhasi bar yechoto chegraphitization inogadzirwa nemhangura uye aluminium. Mhangura ine high mechanical simba, yakanaka magetsi conductivity uye yakasimba corrosion resistance. Aluminium ishoma kuita conductive, asi aluminium yakachipa uye ine huremu hwakareruka.
Tafura 3-2 Inoenderana nekuita data yemhangura nealuminium
| 材 料 | 比重 | 极限强度(MPa) | 电阻率(µΩm) | 电阻的温度系数(1/℃） |
| 紫 铜 | 8.9 | 220 | 0.016 | 4.3×10-3 |
| 铝 | 2.7 | 110 | 0.025 | 4.7×10-3

Sezvo kupisa kwechoto kwechoto che graphitization kuduku, kunyanya muchikamu chekupedzisira chekufambisa simba, kupikisa kwechoto kunova kuduku, uye kudonhedzwa kwekumanikidzwa kwemambure mafupi kunowedzera, zvichiita kuti kuwedzera kwekurasikirwa kwesimba. Naizvozvo, kana graphitization furnace inogona kushanda zvakachengeteka uye mune zvehupfumi ine hukama hwepedyo nehunhu hwemambure mapfupi.
Iyo yakanyanya musimboti ndeye kudzikisira iyo impedance yemambure mapfupi uye chengetedza iyo yese mambure mapfupi nekudonha kudiki kwekumanikidza. Kune akasiyana maitirwo mupfupi mesh ye graphitization furnace. Kana paine kusangana pakati peiyo conductive electrode nebhazi remhangura, kusangana pakati pemhangura nyoro bhazi uye bhazi realuminium, kusangana pakati pebhazi realuminium, nezvimwe, mabatiro aya anoburitsa kupikisa kuramba, zvichikanganisa maitiro eiyo mambure mapfupi. . Iko kusangana kwekupokana kwemutyairi ane poindi yekubatanidza kunoenderana kwete chete nechimiro chechinhu, asiwo nenzvimbo yekusangana uye kudzvanywa kwekubata panguva yekubatana. Nechikonzero ichi, iyo inonyanya kukosha kana uchibatanidza mabhasi ndeye: iyo polishing yakasimba.
Tafura 3-3 Bata kuramba kwe1cm2 graphite uye 1cm2 simbi
