粉煤灰提取氧化铝原料质量检测误差分析及解决措施

Error analysis and solution of quality test of alumina raw material extracted by fly ash

高铝粉煤灰是传统氧化铝生产的重要替代原料,粉煤灰检测可以有效判断粉煤灰质量、评估粉煤灰加工利用价值,粉煤灰检测专业技术较强、精度要求高、检测项目复杂。粉煤灰是复杂的混合物,人为操作、仪器偏差、检测方法的选择等系统误差均会造成粉煤灰检测结果出现偏差。为了降低粉煤灰检测结果误差,提高粉煤灰检测结果对生产的指导作用,文章讨论了粉煤灰检测工作中常见的误差,并分析了粉煤灰检验工作误差的控制。

High alumina fly ash is an important alternative raw material for traditional alumina production.Fly ash detection can effectively judge the quality of fly ash and evaluate the processing and utilization value of fly ash.Fly ash detection has strong professional technology,high precision requirements and complex detection items.Fly ash is a complex mixture.Systematic errors such as human operation,instrument deviation,and selection of detection methods will cause deviation of detection results.In order to reduce the error of fly ash test results and improve the guidance of fly ash test results on production,this paper discusses the common error in fly ash test,and analyzes the control of the error in fly ash test.
