摘要： PROBLEM TO BE SOLVED: To provide a method for sealing an electric galvanizing line drying furnace, capable of increasing a furnace temperature by improving the sealing performance of a flange of the drying furnace, and free from problems on oxidation of a steel shell and damage to lining due to the generation of a clearance gap on a refractory material lining part in the furnace. SOLUTION: A heating area 1, a soaking area 2 and a throat area 3 respectively have a structure formed by lining the refractory material on a steel shell. This method includes a process for pressure bonding a fire-resisting seal member obtained by packing ceramic fiber with alumina cloth with compression rate of 50-70%, from a flange joining part of at least one of the heating area 1 and a soaking area 2, and the throat area 3 to a lining refractory material part adjacent to the flange joining part, a process for arranging by sliding and inserting the throat part to a clearance gap between the compressed fire-resisting seal member and the heating area or the soaking area, and a process for expanding the fire-resisting seal member by weakening the compression force after disposing the throat part.
