Title:
HEAT INSULATING FURNACE FOR ALUMINUM MELT
Document Type and Number:
Japanese Patent JP3198207
Kind Code:
B2
Abstract:
PURPOSE: To reduce the time required for raising the temperature of a crucible and energy consumption costs.
CONSTITUTION: A heat insulating furnace for aluminum melt comprises a crucible 3 capable of containing the aluminum melt, a furnace body 1 supporting the crucible 3 in a surrounding relationship and a pair of burners 5, 6 facing free space 2 defined between the crucible 3 and the furnace body 1 and alternately effecting the supply of combustion air and the discharge of combustion gas through a thermal storage matter. A partition wall 20 is provided in the free space 2 in order to partially separate the pair of the burners 5, 6 from each other. The combustion gas of high temperature flows around the partition wall 20 and is prevented from taking short pass to exhaust line so that the combustion gas is made to flow around the crucible before being discharged.
