Method for processing ceramic coating electric heating roller

A method for processing a ceramic coating electric heating roller relates to the method for processing a heating ceramic material heating roller. A heating method of a product is very simple, and the heating is uniform and energy-saving. The method comprises the following main processing steps: 1) manufacturing a roller core; 2) coating a ceramic insulating layer; 3) coating a ceramic electric heating layer; and 4) surfacing, namely grinding an outside surface of the ceramic electric heating layer until roughness Ra is 0.80 to 0.025. The method is characterized in that: (1) the heating layer of the surface of the roller body is thinner, so the calorific capacity can be reduced, and the heating time can be shortened; (2) the heating layer is made of the ceramic material, the rigidity is proper and wearable, so the durability is excellent; and (3) uniform heating of the heating roller can be ensured only by strictly controlling a coating process and making the coated coating uniform.
