    • PROBLEM TO BE SOLVED: To provide a method of estimation of percent coke contraction which is simple yet allows an accurate estimation of a percent contraction of coke in cokemaking using blended coke.
      SOLUTION: The estimation of a percent coke contraction of blended coke in cokemaking using blended coal as the raw material in which more than one kind of individual brand coal is blended in a specific ratio comprises estimating the reflectance distribution of the vitrinite structure of the blended coal from the reflectance distribution of the vitrinite structures of the individual brand coals and the blend ratio, obtaining the distribution width and estimating the percent coke contraction of the blended coal using the arithmetic average percent coke contraction of the blended coal obtained by weight-averaging based on the distribution width and the blend ratio. The percent coke contraction of an average quality blended coke estimated from the average reflectance of the blended coal obtained based on the blend ratio of the individual coals may also be used. The cokemaking process comprises placing a blended coal adjusted using the method of estimation in the carbonization chamber and carbonizing it.

    • PROBLEM TO BE SOLVED: To provide a method for producing coke, capable of making the oven width directional shrinking amount of the coke in C/S side as larger and performing the discharge of the coke smoothly by a slight improvement in charging equipment for a coal column and also by using the same blended coal.
      SOLUTION: This method for producing the coke is provided by, in the coal column, piling the coal by segregating the particle size over the oven length direction so that the mean particle size of the charged coal becomes finer than the mean particle diameter of the total coal charged in the coal column regarding to at least a coke-discharging side (C/S) from the coke-discharging side (C/S) and the coke-pushing out side (M/S) of carbonizing chambers in the oven length direction of the coke oven, loading into the hoppers of a coal-charging vehicle by keeping that state, charging the coal into the coke oven by keeping the particle size segregation among hoppers and then dry-distilling.

    • PROBLEM TO BE SOLVED: To provide a method for repairing a coke oven door whereby not only repairs are rapidly conducted but also the operating life after repairs of a material used for repairs can be more prolonged than by a conventional method.
      SOLUTION: A conventional method for repairing a coke oven door is improved. The improved method uses both of a first adhesive whose adhesive strength arises at an elevated temperature and a second adhesive whose adhesive strength arises at room temperature. The first adhesive is preferably polyvinyl alcohol and the like; the second adhesive is preferably an inorganic glass frit. Thus, repairs can be rapidly and easily conducted and the operating life of repaired part is far more improved in comparison with a conventional method.
