PURPOSE:To prevent sticking and depositing of formed material by deoxidation and to improve an erosion resistance by forming a zirconia layer and an electric conductive material layer brought into contact with the rear face of the zirconia layer on a wall surface of sliding nozzle plate brought into contact with molten steel. CONSTITUTION:The sliding nozzle plate body 1 consists of a sintering material of alumina quality and the inner surface 2 thereof passes through the molten steel consists of the sintering material of zirconia. Further, the part 3 corresponding to the rear face of the layer 2 is formed by the electric conductive material layer. As the electric conductive material, for example, carbon forming material, carbon powder, carbon containing forming material, etc., is used. |
