Abstract

A method for estimating the thermal plasticity of coal and a caking additive by observing the thermal plasticity of coal and a caking additive under the condition that sufficiently simulates an environment surrounding thermal plastic coal and a caking additive in a coke oven and to provide a method for preparing coal of a brand having a specified quality by making clear the required quality of a coal brand which can be ideally used for manufacturing high-strength coke by using the estimation method. A method for preparing coal for coke making, the method including adjusting a permeation distance of one or more kinds of coal to a specified value or less when plural coal brands are blended as materials to be used for coke making is used.
