| description | PROBLEM TO BE SOLVED: To prevent explosive fracture of an executed product with heated steam in the case of spraying dense unshaped refractory to a surface of a material to be executed having residual heat by specifying spraying thicknesses of first and second layers in the case of spraying the refractory to the heated material. SOLUTION: A lining of various molten metal containers such as a tundish or atmosphere furnace is constructed by a hot spraying method. In the case of spraying dense unshaped refractory to heated material 6 to be executed, a spraying thickness of a layer 8 is set to 10 to 30mm, and spraying thicknesses of layers after a layer 9 are each set to 30 to 100mm. Immediately after spraying of the layers, benching holes each having a diameter of 2 to 10mm are provided at a gap of 30 to 100mm at the executing surface. As refractory composition to be used, low cement castable or cementless castable is included. The low cement castable is preferably prepared by mixing dispersant with refractory composition containing refractory aggregate, refractory ultrafine powder and alumina cement. |
