摘要
为了获得最佳的分级机工艺参数,以进口产品为参考标准,采用四因素、四水平的正交实验方法设计分级实验,考察各因素对分级后钎剂的平均粒径及体积分布的影响.通过对实验的结果进行极差和方差的综合分析,结果表明:各因素对考察指标影响的大小顺序为二级频率>一级频率>风门状态>主机频率;最优组合为主机频率5Hz,一级频率10Hz,二级频率20Hz,风门状态为全开;二级频率对平均粒径及体积分布的影响显著.最后采用优化组合工艺制备了分级的钎剂,并且进行了激光粒度分析并与进口产品对比,表明所制备的分级钎剂的各项指标均与进口产品一致.
In order to obtain the best technological parameters of the classifier and with a standard of the imported product,the orthogonal experiment is designed with four factors and four levels. Based on the analysis of the three indexes including average particle size and the volume distribution of the flux after the classification and comparing the range analysis and variance analysis, the experimental results show that the influence sequence of each factor on the three indexes is as follows： second frequency 〉 primary frequency〉ventilation door〉main frequency. And the optimal combination is the main frequency 5Hz, primary frequency 10Hz, secondary frequency 20Hz, and the ventilation door is full open. The secondary frequency has a significant effect on the average particle size and volume distribution. The particle size analysis of the flux which employs optimized combined classification technology is carried out by laser particle size analyzer, which indicates that the indexes of the prepared packing are consistent with the imported products.
