摘要： PROBLEM TO BE SOLVED: To provide a refractory construction method for keeping durability and having a long service life under severe conditions such as a gas atmosphere including an alkaline component of high temperature. SOLUTION: This construction method of a refractory 600 applied to the inside of a kiln and exposed to hot in the gas atmosphere including the alkaline component, comprises a process for lining the refractory 600 to the inside of the kiln, and a process for coating a surface of the lined refractory with a coating material 605 melting at 750°C or more, mainly composed of silica, and including oxide of alkali metal and alumina. By forming a film by applying the coating material, the coating material reacts with the alkaline component and forms a vitrified layer, thus the intrusion of a gas including the alkaline component to the refractory can be surely prevented in comparison with a case free from the application of the coating material, the durability can be improved, and the service life can be elongated.
