SEALING MATERIAL FOR REPAIRING REFRACTORY BRICKS AND REPAIRING METHOD OF REFRACTORY BRICKS USING THE SAME

摘要

PURPOSE: A sealing material for repairing the wall of a blast furnace and a method for repairing the wall of the blast furnace using the same are provided to use a carbon fiber capable of being melted in molten iron, thereby removing inconvenience for removing the sealing material in re-blowing. CONSTITUTION: A sealing material for repairing the wall of a blast furnace(100) is a carbon fiber(50). In a process for repairing the wall, the material on charging materials(70) piled up on molten iron(90) inside the furnace prevents heat transfer from the bottom of the furnace to the top of the furnace. The fiber has multiple holes. The thickness of the fiber is 15 mm or less. [Reference numerals] (AA) The present invention; (BB) Conventional
