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 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.

摘要： Provided is a method for producing metallurgical coke excellent in terms of the quality of strength and the like compared to that produced through a conventional method. This method for producing metallurgical coke uses a caking additive that exhibits a significant effect in improvement of the strength of metallurgical coke and that is selected by accurately assessing the plastic properties of the caking additive added to mixed coal, by measuring the plastic properties in a state that simulates the surrounding environment of the plasticized coal and caking additive in a coke oven. The method for producing metallurgical coke is characterized in that when carbonizing coal and producing coke, the penetration distance of the caking additive is measured, and caking additive having a penetration distance of a prescribed value or lower is added to coal and followed by carbonization thereof. In addition, the coking additive for use in the production of metallurgical coke: heat treats organic material that contains ash in the amount of 1 mass% or less and that plasticizes in a temperature range between 300°C and 550°C, or treats the organic material in an oxygen-containing atmosphere that is room temperature or warmer; and has a penetration distance reduced to a prescribed value or lower.

摘要： Provided is a technology that evaluates the affinity of coals in coke production and evaluates adhesion strength when carbonizing two types of coal on the basis of the physical properties of coal in order to produce coke having a desired strength by blending coals taking into consideration affinity. The surface tension is measured of two types of semi-coke obtained by heat-treating two types of coal, obtaining the measured values thereof. On the basis of the difference in the obtained two surface tension measured values, the suitability of the adhesion between the two types of coal is evaluated.
