Graphite lub luag haujlwm yog cov khoom hluav taws xob hauv hluav taws xob arc (EAF los ntawm nws cov tshuaj tsis sib xws ntawm arc - raws li steelmaking.
Vim li cas graphite?
Siab melting point: Graphite sublimes ntawm ~ 3,600 degree, deb tshaj li Eaf kev ua haujlwm kub (1,500-3,000 degree), ua kom muaj kev ntseeg siab txheej txheem.
Kev tiv thaiv qis: Muaj kev tiv taus tsawg li muaj 15 μω ·, graphite minimizes minimizes tsis muaj zog thaum muaj kev kis tau los, txo cov nqi ua haujlwm.
Thermal poob siab tsis kam: Graphite tsawg thermal expansion (2-4 × 10⁻⁶ / degree) tso cai rau nws kom tiv thaiv ceev kub hloov (piv txwv li arc pib / cessation) yam tsis tau tawg.
Oxidation tsis kam: Ntawm 1,500-3,000 degree, graphite oxidizes maj mam piv rau cov hlau lossis ceramics, txuas ntxiv lub neej.
Cim npe nrov: Graphite raws li elc hluav taws xob, Tuam Tshoj graphite raws li electrode rau arc rauv taws manufacturers, lwm tus neeg, Hoobkas
