Title:
HEAT PRESERVING SYSTEM FOR MOLTEN METAL HOLDING FURNACE
Document Type and Number:
Japanese Patent JP2001248970
Kind Code:
A
Abstract:

To eliminate an inconvenience of indispensably causing a short lifetime of a molten metal holding furnace due to local heating of a molten metal of the furnace caused by a small thermal conductivity of a combustion gas of a preheated medium by using a gas burner as a heating means in the furnace.

The molten metal holding furnace A is disposed in a fluidized- bed furnace 10. In this case, the furnace A or the molten metal M is uniformly heated in the furnace 10 having high thermal conductivity of the preheated medium to prolong a lifetime of the furnace. Further, a fluidized-bed 2 of the furnace 10 is made of a far infrared generating substance. Thus, the furnace A and the metal M is heated from its interior, and further more uniform heating is realized.
