A structure for manufacturing castings, containing an inorganic fiber, a layered clay mineral, and an inorganic particle other than the layered clay mineral and having an organic content of 5 mass % or lower or having a mass loss of 5 mass % or lower when heated at 1000&#xb0; C. for 30 minutes. The inorganic particle preferably contains one or more selected from obsidian, graphite, and mullite. The inorganic fiber preferably contains carbon fiber. The inorganic fiber preferably has an average length of 0.5 to 15 mm. The layered clay mineral preferably contains one or more selected from bentonite and montmorillonite.

Structure for producing cast

A method for producing a coated material having an oxidizable metal-containing coating, including the step of applying to a base material () an oxidizable metal-containing coating fluid containing a particulate oxidizable metal, a carbon component, a thickener, and water using a coating apparatus () and a coating fluid preparation step in which a thickener solution prepared by dissolving the thickener in water, the particulate oxidizable metal, and the carbon component or an aqueous dispersion of the carbon component are put and mixed in a preparation tank () to prepare the oxidizable metal-containing coating fluid. In the coating fluid preparation step, the particulate oxidizable metal is added to the thickener solution. The coating apparatus () includes a relay tank () capable of temporarily storing the coating fluid to be fed from the preparation tank () to a coating unit (), so that the oxidizable metal-containing coating fluid in the preparation tank () is fed to the coating unit () through the relay tank ().
