Abstract
A method for evaluating the thermoplasticity of a coal or a caking additive with an apparatus including a container for coal and a stirrer located in the container. The method includes estimating a permeation distance of the coal or caking additive from a value indicating a shape of semicoke formed by rotating the stirrer while heating the coal or caking additive and from a correlation between the value indicating the shape of the semicoke and the permeation distance of the coal or caking additive.
