HIGH-CHROMIA-ENRICHED CASTABLE REFRACTORY, PRECAST BLOCK USING THE REFRACTORY AND WASTE MELTING FURNACE LINED WITH THE REFRACTORY AND/OR THE BLOCK

摘要

PROBLEM TO BE SOLVED: To provide castable refractory for a waste melting furnace which is high-chromia-enriched to utilize characteristics of chromia and excellent in both heat impact resistance and corrosion resistance, although being dense and high-chromia-enriched, and its precast block.SOLUTION: High-chromia-enriched refractory contains 1-10 wt.% of a fine-particle mullite raw material of 200 μm or smaller. Its precast block is also provided.
