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： Provided is a coal mixture of which a coal blend is composed and with which it is possible to maintain a high level of coke strength after the carbonization of the coal blend has been performed, even in the case where coal having an excessively large permeation distance is used in a large amount. Large-permeation-distance coal has a permeation distance of more than the value of the permeation distance derived by using equation [I] below. Permeation-distance-decreasing coal has a mean maximum vitrinite reflectance Ro of 1.25% or more and a total inert amount TI of 30 vol.% or less. The blending ratio of the permeation-distance-decreasing coal in the coal mixture is in a range derived by multiplying the blending ratio of the large-permeation-distance coal by 0.25 or more and 3.0 or less. Permeation distance = 1.3 × a × logMF where a is a constant defined as a coefficient of the common logarithm logMF of Gieseler maximum fluidity MF multiplied by a value in the range of 0.7 or more and 1.0 or less, when a regression line that passes through the origin is drawn based on data sets of permeation distance and logMF which are measured for at least one of coal brands having a logMF of less than 2.5.

摘要： Provided is a method of reliably measuring softening and melting properties of coal (non- or slightly-caking coal particularly) for which evaluation of the softening and melting properties was difficult, and evaluating, when the measured coal is used in a coal blend, whether or not coke strength is significantly reduced. This method of evaluating coal is a method of evaluating coal that is used as coke feedstock, and evaluates coal using, as an index, a property value relating to softening and melting properties of the coal to which a primary or secondary amine compound having an aromatic ring has been added to improve the softening and melting properties.

摘要： Provided is a coal-containing mixture configured from blended coal, whereby a high degree of strength of coke obtained by dry distillation of the blended coal can be maintained even when a large amount of coal having an excessive penetration distance is used. In the present invention, a high-penetration-distance coal has a penetration distance exceeding the penetration distance value calculated by equation [I]. In the present invention, a penetration-distance-reduced coal has a vitrinite average maximum reflectance (Ro) of 1.25% or greater and a total amount of inert components of 30 vol% or less. In the coal-containing mixture, the ratio of penetration-distance-reduced coal is in the range of 0.25-3.0 times the ratio of high-penetration-distance coal. (Equation [I]): Penetration distance = 1.3 × a × log MF, where the constant a is a constant in the range of 0.7 to 1.0 times the coefficient of the common logarithm log MF of the Gieseler maximum fluidity MF when a regression line through the origin is created using the measured penetration distance and the value of log MF for at least one type of coal for which log MF is in the range of less than 2.5.
