Chowotcha cha graphite:
Thegraphite chowotchazigawo zikuluzikulu ntchito mu ng'anjo mkulu kutentha ndi kutentha kufika madigiri 2200 pa zingalowe chilengedwe ndi 3000 digiri mu deoxidized ndi anaikapo mpweya chilengedwe.
Zofunikira zazikulu za chowotcha cha graphite:
1. kufanana kwa mawonekedwe a kutentha.
2. zabwino madutsidwe magetsi ndi mkulu magetsi katundu.
3. kukana dzimbiri.
4. inoxidizability.
5. mkulu mankhwala chiyero.
6. mphamvu zamakina apamwamba.
Ubwino wake ndi wogwiritsa ntchito mphamvu, wamtengo wapatali komanso wocheperako.
Titha kupanga anti-oxidation ndi moyo wautali wautali wa graphite crucible, nkhungu ya graphite ndi magawo onse a chowotcha cha graphite.

Chotenthetsera cha graphite cha ng'anjo yamagetsi chimakhala ndi mphamvu yokana kutentha, kukana kwa okosijeni, kuwongolera bwino kwamagetsi komanso kulimba kwamakina. Titha makina osiyanasiyana chotenthetsera graphite malinga ndi mapangidwe a makasitomala.
