摘要： PROBLEM TO BE SOLVED: To provide a method for charging crops by selecting at priority the crop profitable to achieve the target components in a charge from keeping many crops containing special elements, and charging into this charge. SOLUTION: The weight and the alloy components of each crop kept in a crop reserving position, are memorized and a primary cutoff is performed at each charge to limit to the selection objective crops. Nextly, the difference between the number of elements in the target components in the charge and the number of elements in the alloy components in each crop, are calculated and classified into a plurality of tables and further, in each table, the priority order to the whole crops, is decided by arranging in higher order of the actual result component value in the crop according to the element in the target component. Thereafter, from the crop having higher priority order, while checking whether the charging weight is over or not, and whether the component is over or not, in the case of charging this crop, the crop is charged into this charge.

摘要： PROBLEM TO BE SOLVED: To provide a method for treating high-temperature slag, by which the slag can be efficiently recovered as valuables without producing strongly alkaline water in the treatment process and without requiring a long time for the treatment.
SOLUTION: The high-temperature slag containing CaO is subjected to primary cooling and subsequently transferred through a cooling device so as to be subjected to secondary cooling. The primary cooling is carried out by such a method that water is sprinkled onto the slag on a pit 2, and the secondary cooling is carried out using the cooling device 10 such as a rotary cooler. Both the primary cooling and the secondary cooling are carried out by means of water cooling in a range that does not generate free water. Since the slag do not contact with free water, the slag with a low CaO content can be obtained without producing strongly alkaline water, as in conventional methods.
