ELECTRIC FURNACE

摘要

PROBLEM TO BE SOLVED: To provide an electric furnace to reduce the operating cost through efficiently recovering a specified gas blown into the furnace body. SOLUTION: This electric furnace is designed to treat a feedstock powder charged into the furnace body 1 under heating in a graphitizing zone (heating zone) 6 and withdraw the resulting graphite powder from the furnace body 1, and is provided with a gas feed means 12 for blowing a specified gas into the interior of the furnace body 1 and exhaust nozzles for discharging the specified gas from the furnace body 1; and the exhaust nozzles is made up of a 1st nozzle 13 through which the specified gas is discharged from the furnace body 1 before it comes to the graphitizing zone 6 and 2nd nozzles 14, 15 through which the specified gas is discharged from the furnace body 1 after it passes through the zone 6.
