Abstract: PURPOSE:To obtain a roller of silicon nitride free from elevation of manufacturing cost, breakage and adhesion of material to be rolled by specializing the surface roughness, material properties, etc., of a groove part of a ceramic roller. CONSTITUTION:This is a ceramic roller of silicon nitride which is a guide roller or a rolling roller used in a hot rolling line and wherein the surface roughness at least in contact with the material to be rolled does not exceed Rmax4mum, the surface is covered with an oxide film, as the material properties, the bending strength exceeds 80kgf/mm<2>, the fracture toughness value exceeds Kic7MPam<1/2> and the hardness exceeds Hk14GPa. Since the oxide film is formed on the sharp worked streaks of the roller surface, the surface is smoothed and the contact friction with the material to be rolled is reduced. Further, when the bending strength or the fracture toughness value comes below this value, the roller is broken in a short time.
