中文摘要：

灰色关联度分析法是对多因素之间发展趋势的相似或相异程度的描述,是灰色理论的一项重要组成部分。首先将各烧结指标赋予权重值,将其划分为3个等级,然后基于灰色关联度法计算出6组试验方案的烧结指标与理想指标之间的关联度,根据关联度排序进而确定出各方案的优劣情况。最终得出印尼海砂最佳配比为7%,最高配比应不大于12%,实际生产表明该方法可行有效。

英文摘要：

The gray correlation analysis is the description of similarity or dissimilarity between multiple factors, it is an important part of grey theory. Firstly, the sintering indexes weights are given artificially. It has been divided into 3 levels, then the correlation degree between each index of 6 groups of test scheme and ideal index by using grey relational analysis has been calculated. According to the correlation degree the merits of each scheme are sorted and determined. Finally, it is concluded that the best ratio of Indonesian sea sand is 7%, and the highest ratio should be not higher than 12%, and the actual production shows that the method is feasible and effective.
