摘要： Provided is a method for producing a galvanized steel sheet that exhibits a low sliding resistance during press forming, exhibits excellent degreasability even under stringent alkali degreasing conditions that involve a low temperature and a short line length, suppresses dissolution of the oxide layer formed, and is capable of suppressing occurrence of unevenness due to a washing treatment. The method includes an oxide layer forming step of bringing a galvanized steel sheet into contact with an acidic solution containing sulfate ions, then holding the galvanized steel sheet in contact for 1 to 60 seconds, and then washing the galvanized steel sheet with water; and a neutralization treatment step of holding a surface of an oxide layer, which has been formed in the oxide layer forming step, in contact with an alkaline aqueous solution for 0.5 seconds or longer, and then performing washing with water and drying. The alkaline aqueous solution contains P ions at a P concentration of 0.01 g/L or more and carbonate ions at a carbonate ion concentration of 0.1 g/L or more.

摘要： Provided is a method for producing a galvanized steel sheet that exhibits a low sliding resistance during press forming, exhibits excellent degreasability even under stringent alkali degreasing conditions (low temperature and short line length conditions), suppresses dissolution of the oxide layer formed, is capable of suppressing occurrence of unevenness due to a washing treatment, and uses treatment solutions that do not have to contain substances of concern. A method for producing a galvanized steel sheet having an oxide layer on a surface includes an oxide layer forming step of bringing a galvanized steel sheet into contact with an acidic solution containing sulfate ions, then holding the galvanized steel sheet in contact for 1 to 60 seconds, and then washing the galvanized steel sheet with water; and a neutralization treatment step of holding a surface of an oxide layer, which has been formed in the oxide layer forming step, in contact with an alkaline aqueous solution for 0.5 seconds or longer, and then performing washing with water and drying.

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 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.
