Abstract: A system and process for rapid and uniform curing of grinding wheels (2) to obtain grinding wheels (2) with better durability, at 180-220° C. deploying microwave energy at 800-5000 MHz in which closely fitting green wheel sample holders (1) are made of carbon bearing microwave susceptor materials such as graphite, silicon carbide with tiny holes on the surface. These sample holders (1) help in maintaining the shape and geometry of the final wheels (2) after curing and reduce energy consumption. The performance of the grinding wheels (2) cured by this process is better than those cured by presently used process employing steel plate sample holders of the present state-of-art.

Abstract: The present invention addresses the problem of providing a heating furnace that sufficiently exhibits the microwave effect produced by microwave heating and allows economical heating taking advantage of the characteristics of each heating method. The provided microwave composite heating furnace (1) is equipped with: a housing (10); a heating container (11) for accommodating and heating an object to be heated; a heating means (12) for heating the heating container (11) from the outside; a microwave irradiation device (13); a to-be-heated object supplying device (14) that supplies the object to be heated to the inside of the heating container (11); a gas introducing means (15) for introducing gas into the heating container (11); and a gas recovery means (16) for recovering the gas generated when heating the object to be heated.
