Zusammenfassung: | PURPOSE:To reduce the skid marks of a material to be treated and to extend the life of a skid button constituted by coating the ceramic skid button with a heat resistant metal by constituting the skid button in such a manner than the thickness of the heat resistant metal and the diameter of the ceramic skid button satisfy the specific equation. CONSTITUTION:The entire surface of the ceramic skid button 2 or the surface thereof to contact with the metal to form the heated is coated with the heat resistant metal to form the skid button S for a heating furnace. The thickness t1 of the heat resistant metallic surface to contact with the material to be treated is made at least 10mm. The diameter of the button 2, designated as d mm and the thickness of the heat resistant metal 1 on the side face of the button S, designated as t2, are so determined as to satisfy the equation (t1/d) |
