Abstract (en)
There is provided a method for producing a metallurgical coke having higher quality such as strength than before, using a coal blend including coals whose thermal plasticity is accurately evaluated by measuring the thermal plasticity of coal in a state in which an environment surrounding plastic coal in a coke oven is simulated. In the method for producing a metallurgical coke by carbonizing a coal blend obtained by blending at least two coals and a caking additive, a sample including the coals and the coking additive that constitute the coal blend is packed in a vessel in a predetermined amount, a material having through-holes that connect upper and lower surfaces is disposed on the sample, the sample is heated at a predetermined heating rate while a constant load is imposed on the material having through-holes that connect upper and lower surfaces, and a permeation distance of the sample that has permeated into the through-holes is measured in advance. Coals and a caking additive whose permeation distance is larger than a predetermined control value are pulverized into particles having a particle size smaller than a predetermined particle size and then blended.
