摘要： PROBLEM TO BE SOLVED: To provide an evaluation method for segregation in a billet and a wire rod in evaluating the segregation in a continuous casting for the billet, wherein the segregation is simply evaluated without requiring skill, and without affected by evaluation dispersion of a short period caused in the casting. SOLUTION: The evaluation method is characterized in that after grinding an L-cross section of the casting including a central segregation part, the solidified structure obtained by corrosion and the segregated structure are transcribed (Etch Print method) as they are or on a tape, and thereafter a transparent rule scored of an equidistant or random distant cross is attached along the central segregation part to conduct the segregation evaluation based on the rate of the overlapping time of a crossing point and a segregation particle. In conducting the segregation evaluation in the wire rod, after cutting the wire rod in the equidistance or the random distance, the quality of the wire rod is evaluated based on the detection rate of the segregation in a C-cross section.

摘要： PROBLEM TO BE SOLVED: To prevent the clogging of a nozzle by regulating the number of remaining alumina having a prescribed grain diameter in molten metal. SOLUTION: In the figure, the relation between the number of the alumina having >=10μm in a sample taken from the molten metal poured into the immersion nozzle and the developing condition of the nozzle clogging, is shown. In this figure, the nozzle clogging has clear correlation with the number of the alumina and it can be prevented to develop the nozzle clogging by indexing and controlling this number of the remaining alumina. That is, the development of the nozzle clogging is prevented by reducing the number of the remaining alumina to (60,000 pieces/kg) and the casting can be stabilized. Further, in order to melt such a molten metal, in the case of being =10μm size in the molten melt can be controlled to .

摘要： PROBLEM TO BE SOLVED: To reduce alumina cluster by adding required amounts of prescribed elements at the time of deoxidizing treatment for molten steel. SOLUTION: According to deoxidation experiments, it is found that alumina cluster is most finely dispersed by adding Zr, Mg, and Ga, having deoxidizing power higher than that of Al, by the amounts represented by inequality after deoxidation with Al. In the inequality: M1 is the atomic weights of the oxidizing elements (Zr, Ca, Mg); M0 is the atomic weight of O; (a) and (b) are the stoichiometric coefficients (where a=1 and b=2 are satisfied in the case of Zr, and a=1 and b=1 are satisfied in the case of Ca and Mg) of the oxide (Xa Ob ) of the deoxidizing elements X; C(X) is total deoxidizing element (where X means one element among Zr, Ca, and Mg) concentration (ppm) in the molten steel; C1 (O) is free oxygen concentration (ppm) in the molten steel before Al addition; and C2 (O) is free oxygen concentration (ppm) in the molten steel after Al addition.
