PURPOSE: When molten pig iron and slag are flowed through blast furnace tapping spout made from silicon carbide and graphite etc. carbide material is coated previously at the place which will be injured by FeO in a molten slag and oxidizing atmosphere. Thereby, endurance life of tapping spout is prolonged.
