BLAST FURNACE HEARTH LINING STRUCTURE
Provided is a blast furnace hearth lining structure having excellent molten iron and slag resistances and high structural spalling resistance. The lining structure of the present invention is based on employing a sialon-bound alumina brick having a ²'-sialon-bound microstructure exhibiting high structural spalling resistance as a lining brick, wherein a first sialon-bound alumina brick 8 prepared by setting an amount of ²'-sialon-originating Si contained in the brick to fall within a specific range is installed in a portion of a blast furnace hearth requiring relatively high molten ion resistance, and a second sialon-bound alumina brick 7 prepared by setting an amount of ²'-sialon-originating O (oxygen) contained in the brick to fall within a specific range is installed in a portion of the blast furnace hearth requiring relatively high slag resistance.
