<p><P>PROBLEM TO BE SOLVED: To provide a refractory-lining structure of a vessel for iron-making, which is easy in working, can reduce working man-days and also can exhibit a thermal-insulating effect for a long period of time. <P>SOLUTION: In the refractory-lining structure of the vessel 1 for iron-making, the molten iron received from a blast furnace is held, the held molten iron is conveyed, or the held molten iron is subjected to a refining treatment. The refractory-lining structure comprises an iron-shell 2, a permanent-refractory layer 3 and a working-refractory layer 4 in this order from the outside of the vessel for iron-making, and a thermal-insulating material 5, whose compression strength is more than the ferrostatic pressure generated when holding the molten iron in the vessel for iron-making is arranged between the iron-shell and the permanent-refractory layer. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
