Title:
HEATING ROTARY FURNACE
Document Type and Number:
Japanese Patent JP2010236822
Kind Code:
A
Abstract:

To provide a heating rotary furnace expecting improvement of heat efficiency.

This heating rotary furnace 10 includes a rotary furnace 12 composed of a magnetic material, and a coil 42 disposed at its outer side. High-frequency power supplied from a high-frequency power source 44 is generated from the coil 42. Induction current is generated at a peripheral side face of the rotary furnace 12 by the high-frequency power, and the peripheral side face of the rotary furnace 12 produces heat by the induction current. The heat is diffused in the rotary furnace 12, thus the inside of the rotary furnace is heated. As a result, the peripheral side face of the rotary furnace produces heat, and heat efficiency is improved.
