Ngokuvamile, ibha yebhasi ephakathi komkhawulo ophumayo wekhabethe 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-Aluminiyamu 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 kumeshi 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.
