A numerical study on the temperature distributions of direct-surface-heating ceramic fuse roller

This report shows that the temperature distributions of the direct-surface-heating ceramic fuse roller are simply calculated by the one-dimensional heat conduction numerical analysis. Although the heated ribon which was wound on to the fuse roller had already been used for an actual photo copier machine, there were still many remaining problems about the temperature distributions, heat capacity, meterial strength and the cost of the ceramic roller. The present report considers that the temperature distributions might be solved by the finite different method taking into account the size of the heat roller, the roller materials and the rotating roller velocity. We obtained the temperature distributions of the heating ceramic fuse roller, the feeding paper, and the gum roller used to press the paper, respectively. We examined numerically the effects of the surface coated non-metalic layer, after that we noticed that we had to pay attention to the effects of the non-metalic layer when we used it.
