Abstract
A method for evaluating thermal plasticity of coals and caking additives includes packing a coal or a caking additive into a vessel to prepare a sample; arranging a through-hole materialhaving through-holes from top to bottom surfaces, onto the sample; heating the sampleat a predetermined heating rate while maintaining a constant volume of or while applying a constant load onto the sampleand the through-hole material; measuring the permeation distance with which the molten sample has permeated into the through-holes; and evaluating thermal plasticity of the sample using the measured value. Alternatively, a method involves heating the sampleat a predetermined heating rate while maintaining the sampleand the through-hole materialin a constant volume; measuring the pressure of the sample that is transmitted via the through-hole material; and evaluating thermal plasticity of the sample using the measured value.
