Title:
コークス製造用石炭の調製方法
Document Type and Number:
Japanese Patent JP5071578
Kind Code:
B2
Abstract:
An object is to provide a method for more precisely estimating the thermal plasticity of coal and a caking additive with a simple method 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. It is preferable that the specified value of a permeation distance be double the weighted mean value of those of the coal brands contained in a coal blend and that the permeation distance of coal be decreased by exposing the coal to an atmosphere containing oxygen.
