摘要： PROBLEM TO BE SOLVED: To provide a lining structure in an industrial furnace such as heating oven and in a furnace with an atmosphere at higher than 1000°C for use in iron making facilities, having excellent FeO resistance, being capable of reducing heat loss in total of radiation heat quantity and storage heat quantity.SOLUTION: The lining structure for use in a furnace for iron making includes a refractory layer. The refractory layer includes: a surface layer material in which porous adiabatic aggregate having CaO-6AlOas a main mineral composition is blended; and a rear face material having physical properties such as lower thermal conductivity and lower bulk density compared to those of the surface layer material when using the furnace. The thickness ratio between the surface layer material and the rear face material is determined such that both of the radiation heat quantity and the storage heat quantity of the refractory layer when using the furnace are smaller than those of the entire refractory layer formed of the surface layer material alone. The surface layer material has a thickness of 10 mm or more.

摘要： PROBLEM TO BE SOLVED: To provide a method for repairing the curved wall of a metal refining furnace steel outlet by spraying to prevent the occurrence of damage due to thermal spoiling of a wall refractory, improve adhesion of a flame spraying material to the refractory of a repair wall, and perform high-efficient repair by a uniform covering layer. SOLUTION: Combustion supporting gas injected through the first route of a multi- shaft multiple-tube burner and combustible gas through the second route thereof are injected in a ratio of 4:1 to 7:1 to form flame to melt and remove residues on the wall surface of a metal refining furnace steel outlet. Immediately or after a refractory for a repair wall is heated to 900 deg.C or higher by the flame, combustion supporting gas from the first route, a flame spraying material by carrier gas from the second route, and combustion supporting gas from a third route are injected for firing, and the flame spraying material is sprayed against the refractory of the repair wall. The flame spraying material is a mixture of 5-12 wt.% alloy powder having a weight ratio between Ca:Si being 25:65 to 35:55 and a grain size of 0.147 mm or less, and 88-95 wt.% fire resistant powder, having a weight ratio between magnesium with a grain size of 1-0.2 mm and magnesia line with a grain size off 1-0.2 mm being 4.5:1 to 2.5:1.
