The present invention relates to a circular multi-layer structure for heat storage and heat dissipation for a waste disposal apparatus using a magnetic force such as a permanent magnet. As an integrated and cylindrical steel structure is processed to allow a diameter to be narrower to be two or more multi-layered (a plurality of stages) toward an upper part, two or more lines from the center of a circle and a plurality of holes for heat storage and heat dissipation are radially formed, and heat treatment is performed more than one time to increase hardness. An outside of a steel structure is coated with ceramic generating far infrared rays, and an inside of the hole for heat storage and heat dissipation is also coated. Therefore, provided is the circular multi-layer structure for heat storage and heat dissipation for a waste disposal apparatus using a magnetic force for improving preservation of heat. |
