摘　　要：采用ICP及XRF等方法分析了本公司工业硅粉中磁性物质的成分。研究结果表明:工业硅粉磁性物质中主要构成为铁、铝、钙3种元素,其中铁元素含量最高。据此在冷氢化下料口增设磁选机设备可减少75%左右的磁性物质,有效提升了工业硅粉的使用效率,保障了生产工艺安全平稳运行。As a result,ICP and XRF were used to analyze the compositions of the magnetic materials within the industrial silicon pow-ders used in our corporation.Our results show that iron,aluminum,and calcium constitute the main magnetic substances in industrial silicon powder.Notably,the iron content is the highest among these elements.To address this issue,we introduce magnetic separator equipment at the cold hydrogenation feeding port,which effectively reduces magnetic material content by approximately 75%.This in-novation not only enhances the utilization efficiency of industrial silicon powder but also ensures the safe and smooth operation of the production process.
