<p><P>PROBLEM TO BE SOLVED: To provide a method of easily selecting and blending scraps that are most suitable for a target steel type, without missing the most suitable scrap and causing the variation of the blend. <P>SOLUTION: This blending method includes: the first step of calculating a content weight of each component element from the amount of the target steel type to be produced; the second step of selecting the scraps containing the component elements of the target steel type; the third step of calculating the amounts of the selected scraps to be charged necessary for attaining the content weight of each component element; the fourth step of setting the smallest value among the calculated charging amounts at temporary charging amounts of the scraps; the fifth step of selecting the scrap showing the largest value of the temporary charging amounts as determined scraps; the sixth step of setting the amounts according to the temporary charging amounts of the determined scraps at the firm charging amounts; and the seventh step of recalculating the content weight of each component element to be attained when the firm charging amounts of the determined scraps have been charged. After that, the scraps and the charging amounts are sequentially determined by repeating the third step to the seventh step. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
