Abstract:
PROBLEM TO BE SOLVED: To provide a method, a heating apparatus, and a heating furnace that involve no difficulty in production and enable a heater to be stably fixed to a thermal insulator.SOLUTION: A heating apparatus 10 has a thermal insulator 11, a heater 12 embedded in the surface of the thermal insulator 11, and hooks 13 extending from the heater 12 into the thermal insulator 11, which is integrally molded with the heater 12 including the hooks 13. It further has an electro-insulative supporting member embedded in the thermal insulator 11, in which the hook 13 embraces the electro-insulative supporting member, the electro-insulative supporting member is hollow and a thermally resistant rod penetrates the hollow member to support the thermal insulator 11. The heater 12 is formed in a meandering shape with slits alternately cut from two side edges of a metal plate; in the parts of the metal plate where the slits are formed, a plurality of hooks alternately opposing each other are formed by bending the metal plate; hooks formed from the metal plate in alternately opposing two rows embrace one electro-insulative supporting member on each row, or a total of two such members.
