使用田口法探索了影响钒钛磁铁矿热压块抗压强度的重要因子，并通过信噪比分析计算各因子对抗压强度的贡献率，最终给出钒钛磁铁矿热压块的最佳制备条件.实验结果表明，在热压温度、配碳比、煤粉粒度三个影响因素中，煤粉粒度对抗压强度的影响程度最大，其贡献率达到了79.99%，温度和配碳比二者的贡献率分别为15%和3.63%.优化后钒钛磁铁矿热压块的制备参数为热压温度300℃、煤粉粒度﹤75μm、配碳比1.8.在优化后的参数下进行验证实验，得到的钒钛矿热压块的平均抗压强度达到1152.1 N.

The Taguchi method was used to explore the important influence factors on the compressive strength of vanadium titanium magnetite hot briquettes,and then the contribution rates of these factors to the compressive strength were calculated through the signal-to-noise ratio analysis.Finally,the best preparation conditions of vanadium titanium magnetite hot briquettes were established.The results showed that among the three processing parameters including the hot-briquetting temperature,carbon ratio and coal particle size,the coal particle size was the most important factor to the compressive strength,and its contribution rate is up to 79.99%,the contribution rates of the hot-briquetting temperature and the carbon ratio were 15% and 3.63%, respectively.The optimized parameters of the preparation process of vanadium titanium magnetite hot briquette are as follow:hot-briquetting temperature 300 ℃,coal particle size less than 75 μm, carbon ratio 1.8.Verification experiments were conducted with the optimized parameters,and the average compressive strength of the vanadium titanium magnetite hot briquette is up to 1 152.1 N.
