摘要：
The present invention provides a moulded object of alumina matter-containing raw material for aluminum smelting by a blast furnace method. The moulded object for aluminum smelting is formed by coating a moulded object comprising the alumina matter-containing raw material and a carbon material with carbon material coating layers on its surface.
