Feem ntau, lub busbar nruab nrab ntawm cov zis kawg ntawm DC graphitization furnace rectifier txee thiab cov hluav taws xob hluav taws xob ntawm lub tshuab hluav taws xob lub taub hau yog hu ua luv luv net, thiab busbar siv nyob rau hauv qhov cub graphitization feem ntau yog duab plaub. Lub busbar ntawm graphitization rauv yog ua los ntawm tooj liab thiab txhuas. Copper muaj zog txhua yam, zoo hluav taws xob conductivity thiab muaj zog corrosion kuj. Aluminium yog me ntsis conductive, tab sis txhuas yog pheej yig dua thiab muaj ib tug sib zog.
Table 3-2 Cov ntaub ntawv kev ua tau zoo ntawm tooj liab thiab txhuas
| 材料 | 比重 | Kev ua haujlwm siab (MPa) | 电阻率 (µΩm) | Kev kub ceev (1 / ℃) |
| 紫 铜 | 8.9 ib | 220 | 0.016 ib | 4.3 × 10-3 |
| | 2.7 | 110 | 0.025 ib | 4.7 × 10-3

Txij li thaum lub cub tawg ua hauj lwm ntawm graphitization cub tawg yog me me, tshwj xeeb tshaj yog nyob rau hauv lub tom ntej theem ntawm lub hwj chim kis tau tus mob, lub cub tawg kuj yuav me me, thiab lub siab poob ntawm lub luv luv net yog nce, uas ua rau ib tug nce nyob rau hauv lub zog poob. Yog li ntawd, seb lub qhov cub graphitization tuaj yeem ua haujlwm tau zoo thiab kev lag luam muaj kev sib raug zoo nrog cov yam ntxwv ntawm cov net luv.
Lub hauv paus ntsiab lus tseem ceeb tshaj plaws yog kom txo qis impedance ntawm luv luv net thiab ua kom tag nrho cov net luv nrog lub siab me me. Muaj ntau yam kev sib cuag nyob rau hauv luv luv mesh ntawm graphitization rauv. Yog tias muaj kev sib cuag ntawm cov hluav taws xob hluav taws xob thiab lub tsheb npav tooj liab, kev sib cuag ntawm lub tsheb npav tooj liab thiab lub tsheb npav txhuas, kev sib cuag ntawm lub tsheb npav txhuas, thiab lwm yam, cov kev sib cuag no yuav tsim kev tiv thaiv kev tiv thaiv, cuam tshuam rau cov yam ntxwv ntawm tag nrho cov net luv. . Kev tiv thaiv kev sib cuag ntawm tus neeg xyuas pib muaj qhov sib txuas tsis yog nyob ntawm qhov xwm txheej ntawm cov khoom, tab sis kuj nyob ntawm thaj chaw tiv tauj thiab kev sib cuag siab thaum lub sijhawm sib cuag. Vim li no, qhov yooj yim tshaj plaws thaum txuas cov busbars yog: polishing yog nruj.
