PROBLEM TO BE SOLVED: To provide a self-lining structure for a furnace top bunker of a blast furnace which clears a problem in the conventional lining and suppresses wear of constituent members of the structure itself. SOLUTION: A steel plate 8 for setting is fixed to the outside of a furnace body steel shell 7 by means of stud bolts 13 and nuts 15, a shelf member 9 is provided in a projected manner from the steel plate 8 for setting toward inside a bunker, and a receiving member 11 is fixed to the distal end of the shelf member 9 by means of a receiving member fixing implement 12, so that charged raw material 3 is deposited on the shelf member 9 and the receiving member 11. The inner wall of the bunker 2 is protected with the deposited charged raw material itself, and the shelf member 9 and the receiving member 11 are covered with the deposited charged raw material 3, and therefore the wear of the constituent members can be suppressed. Further, only the most wearing receiving member 11 is required to be repaired and replaced, consequently repair is facilitated and at the same time, the working time and cost of the repair can be reduced.
