Annular vibration heating furnace

The invention belongs to the technical field of heating furnaces and discloses an annular vibration heating furnace which comprises a heating furnace body, and the heating furnace body is sequentially provided with an electromagnetic induction layer, a vibration generation layer, an anti-vibration damping layer and an outer frame layer from inside to outside. A plurality of reciprocating compressors are arranged on the heating furnace body in the circumferential direction, a plurality of ventilation pipes are arranged in the vibration generation layer in the circumferential direction, the two ends of each ventilation pipe communicate with the corresponding reciprocating compressors correspondingly, and the reciprocating compressors generate periodic airflow pulsation in the corresponding ventilation pipes; when materials are heated in the annular heating furnace, airflow pulsation is generated on the ventilation pipe in the vibration generation layer through the reciprocating compressor, so that resonance is
