摘要： There is provided a method for blending coals for coke production, in which the strength of coke produced from a coal blend serving as a raw material is estimated using a physical property that has not been taken into consideration in the past as an index, so that the method is capable of suppressing an increase in the raw material cost of the coal blend and increasing the strength of coal. Two or more coal brands are blended together to provide a coal blend for coke production. When the two or more coal brands are blended together, the coal brands and the blending ratio of the coal brands are determined using the surface tension of each of the coal brands subjected to heat treatment, the surface tension serving as a control index.

摘要： Provided is a method for accurately measuring the thermoplasticity of a coal (in particular, non- or slightly caking coal) whose thermoplasticity has been difficult to evaluate and determining whether the coal that is to be measured does not significantly reduce the coke strength when used for a coal blend. The evaluating method for a coal according to the present invention is a method for evaluating a coal used as a raw material for coke and includes using a physical property value relating to a thermoplasticity of a coal as an index for evaluating the coal, wherein a primary or secondary amine including an aromatic ring have been added to the coal, thereby enhancing the thermoplasticity of the coal.

摘要： A method for preparing coal for coke making includes controlling the size of particles of an individual brand of coal or caking additive prior to arrival at a coke plant so that the content of particles having a diameter of 6 mm or more in the individual brand of coal or caking additive reaches 30% by mass or less when the individual brand of coal or caking additive has a permeation distance of 15 mm or more. In another method for preparing coal for coke making, on the basis of the relationship between a critical permeation distance and a Gieseler maximum fluidity obtained using permeation distances and the values of Gieseler maximum fluidity of one or more brands of coal or caking additive, the size of particles of an individual brand of coal or caking additive is controlled prior to arrival at a coke plant so that the content of particles having a diameter of 6 mm or more in the individual brand of coal or caking additive reaches 30% by mass or less when the permeation distance of the individual brand of coal or caking additive is larger than or equal to a critical permeation distance calculated from a Gieseler maximum fluidity of the individual brand of coal or caking additive on the basis of the relationship between the critical permeation distance and the Gieseler maximum fluidity.

摘要： Provided are, by using an index with which the influence on the strength of coke can be evaluated, a method for evaluating a weathering degree of coal and a coking property of weathered coal within the ranges in which the weathering degree and coking property cannot be determined by using conventional methods, and a method for controlling the weathering degree of coal with which it is possible to add weathered coal to a coal blend to be used for producing coke without decreasing the strength of coke by using the index. The weathering degree of coal is evaluated by using the surface tension of semicoke which is prepared by performing a heat treatment on weathered coal as an index. Moreover, the surface tension of each brand of semicoke which is prepared by performing a heat treatment on each of the plural brands of coal included in coal stock is previously determined. In addition, the proportion of each brand of coal to the whole coal stock is also previously assessed. The weathering degree of each brand of coal is controlled so that the interfacial tension ³ inter of a semicoke blend which is prepared by blending the plural brands of semicoke in accordance with the proportions is 0.03 mN/m or lower.

摘要： An object is to provide coke having a high strength and excellent extrusion capability from a coke oven and a method for manufacturing the coke. In addition, provided is a method for quantitatively evaluating homogeneity of a coal blend. Using a mixing apparatus having a capability of controlling a degree of mixing to be 0.85 or more at 60 seconds after the start of a mixing and stirring operation when stirring and mixing a coal blend makes it possible to disintegrate pseudo-particles in the coal blend in order to homogenize the coal blend. Therefore, it is possible to manufacture coke excellent in terms of coke strength and extrusion capability. The degree of mixing is defined by equation (1): degree of mixing = ÃC 0 ˆ’ ÃC / ÃC 0 ˆ’ ÃCf Here, the degree of mixing is a value calculated from the standard deviation of characteristic values respectively determined for the samples taken from the stirred and mixed coal blend. ÃC 0 denotes the standard deviation of a characteristic value when mixing is not entirely performed, ÃCf denotes the standard deviation of characteristic values when mixing has been completely performed, and ÃC denotes the standard deviation of respective characteristic values of the samples taken.

摘要： 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.
