Summary:PROBLEM TO BE SOLVED: To provide a method for constructing a hot-blast divided tube in a hot-stove for blast furnace, wherein various problems related to an elastic coupling can be avoided by dispensing with the elastic coupling. SOLUTION: The lengths of the vertical part 6 and the horizontal parts 5, 7 of the hot-blast divided tube 4, are respectively made to be three or more times the tube diameter, thereby, even when the difference of the heat-displacement or the heat-displacement itself is caused, the heat-displacement can be absorbed with the elastic deformation of the tube itself. As a result, an elastic coupling is not needed to use and the various problems related to the elastic coupling can be avoided. COPYRIGHT: (C)2011,JPO&INPIT
