Ngokuvamile, ibha yebhasi ephakathi kokuphela kokuphumayo kwekhabethe le-DC graphitization furnace rectifier kanye ne-electrode conductive yekhanda lesithando ibizwa ngokuthi inetha elifushane, futhi ibha yebhasi esetshenziswa esithandweni se-graphitization ngokuvamile inonxande. I-busbar yesithando somlilo se-graphitization yenziwe ngethusi ne-aluminium. I-Copper inamandla amakhulu emishini, ukuhamba kahle kukagesi kanye nokumelana nokugqwala okuqinile. I-Aluminium ayihambisani kancane, kodwa i-aluminium ishibhile futhi inesisindo esilula.
Ithebula 3-2 Idatha yokusebenza ehambisanayo yethusi ne-aluminium
| 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

Njengoba ukumelana kwesithando somlilo wesithando se-graphitization kuncane, ikakhulukazi esigabeni sakamuva sokudluliselwa kwamandla, ukumelana nesithando somlilo kuba kuncane, futhi ukwehla kokucindezela kwenetha elifushane kwanda, okuholela ekwandeni kokulahlekelwa kwamandla. Ngakho-ke, noma ngabe isithando somlilo se-graphitization singasebenza ngokuphepha nangokwezomnotho sinobudlelwane obuseduze nezici zenetha elifushane.
Umgomo oyisisekelo kakhulu ukunciphisa ukuvinjelwa kwenetha elifushane futhi ugcine yonke inetha emfushane nokwehla kokucindezela okuncane. Kukhona othintana nabo abahlukahlukene ku-mesh emfushane yesithando somlilo se-graphitization. Uma kukhona ukuxhumana phakathi kwe-electrode conductive kanye nebhasi lethusi, ukuthintana phakathi kwebhasi elithambile yethusi kanye nebhasi le-aluminium, ukuthintana phakathi kwebhasi le-aluminium, njll., laba othintana nabo bazoveza ukumelana nokuxhumana, okuthinta izici zayo yonke inetha elifushane. . Ukuphikiswa kokuxhumana komqhubi onephuzu lokuxhuma akuxhomekile kuphela esimweni sezinto ezibonakalayo, kodwa futhi endaweni yokuxhumana kanye nengcindezi yokuxhumana ngesikhathi sokuxhumana. Ngenxa yalesi sizathu, okuyisisekelo kakhulu lapho uxhuma amabhasi: ukupholisha kuqinile.
