Imininingwane Yemikhiqizo
Ama-electrode athwala ugesi oshisisa ama-arc kagesi, iziko elikhulu lensimbi. Zenziwe nge-petroleum coke ngemva kokuba ixutshwe ne-petroleum pitch, ikhishwe futhi ibunjwe, bese ibhakwa ukuze ifakwe emanzini, bese yenziwa imidwebo ngokuyishisisa ngaphezu kwezinga lokushisa (3000 °C) eliguqula ikhabhoni ibe yigraphite. Zingahluka ngosayizi kuze kufike ku-11 ft ubude no-30 in.
Ukusetshenziswa
- 01 Ingxenye ekhulayo yensimbi yomhlaba wonke yenziwa kusetshenziswa amafurnace kagesi
- 02 Isithando somlilo se-arc sikagesi ngokwaso siya ngokuya sisebenza kahle futhi senza insimbi eyengeziwe ngethani ngalinye le-electrode
