This study is concerned with the caking effects of HPC (High Performance Caking additive), which is produced by thermal extraction and solvent de-ashing in the coal derived methylnaphthalene solvent. Significant improvement in the thermoplasticity of coal blends are observed by HPC addition. Synchronized with it, strong improvement in dilatation is also brought especially with high blending ratio of slightly caking coals. It is confirmed that the improvement of dilatation is the dominant factor to perform filling the inter particle voids of coals in the coking reaction, that brings strong adhesive of coal particles to form a lump strong coke for blast furnace. In the same meaning, the increasing in the charging bulk density of coal affects to decrease in the inter particle voids. The changing in the coke strength is quantitatively investigated as the synergic effect of those factors.
