UHP 550 hli Graphite Electrode
Graphitization yog ib theem tseem ceeb heev hauv UHP graphite electrode ntau lawm. Nws hais txog cov txheej txheem kev kho cua kub kub ntawm cov khoom siv carbon saum toj no 2300 ℃ hauv lub qhov cub hluav taws kub kub kom hloov cov amorphous chaotic txheej txheej carbon rau hauv peb-dimensional xaj graphite siv lead ua qauv.
Dab tsi yog lub luag haujlwm ntawm graphitization?
* Txhim kho cov hluav taws xob thiab thermal conductivity
* Txhim kho cov thermal shock tsis kam thiab tshuaj lom neeg ruaj khov (qhov linear expansion coefficient yog txo los ntawm 50-80%);
* Ua kom cov khoom siv carbon muaj lubricity thiab hnav tsis kam;
* Tshem tawm impurities thiab txhim kho qhov purity ntawm cov khoom siv carbon (cov hmoov tshauv ntawm cov khoom raug txo los ntawm 0.5% txog 0.3%).
