炭素体を黒鉛化するためのシステム - SGE L Carbon Gezel Shaft Mitt Beschlenktel Haftung Und Compani

Title:

炭素体を黒鉛化するためのシステム

Document Type and Number:

Japanese Patent JP4515040

Kind Code:

B2

Abstract:

Post-coking and graphitizing carbon bodies impregnated with pitch comprises forming a strand from the carbon bodies, and surrounding with a thermal insulating layer. Before heating the carbon bodies, the oxygen content in the furnace is reduced to less than 4 vol.% so that an electrical current can be passed through the strand. The gas pressure is regulated so that it deviates by +10 to -40 Pa from the external air pressure. Gases and/or vapors produced from the carbon bodies and/or from the insulating layer are removed from the furnace using a suction device. An Independent claim is also included for a furnace sink for carrying out the process.
