以加料均匀性系数和料液有效利用率为评价指标，采用均匀设计方法研究了热风温度、排潮风门开度、循环风门开度、热风电机速比、喷嘴压缩空气压力对料液施加效果的影响。结果表明：①以加料工序关键工艺参数与加料均匀性系数、料液有效利用率构建的二次多项式模型具有较高拟合度，R2分别为0.9889、0.9922，较好地描述各工艺参数与料液施加效果之间的关系。且通过贡献率分析，热风温度对加料均匀性的贡献率最大，贡献率α为1.8295，而热风电机速比对料液有效利用率贡献率最大，贡献率α为2.3386。②最优加料工艺参数为：热风温度45.0℃，循环风门开度45.0%，排潮风门开度50.0%，热风电机速比70.0%，喷嘴压缩空气压力0.35 MPa。经生产应用验证，该参数下加料均匀性系数达到95.03%，料液有效利用率达到65.90%，较对照分别提高了2.60%、5.80%。

The casing process was assessed on the basis of casing uniformity coefficient and the effective utilization rate, the parameters including hot air temperature, the opening of the exhausted valve, the opening of circulation air valve, the speed ratio of motor for hot air, compressed air pressure for the nozzle were studied with uniform design method. The results showed that: 1) The relationship model established with stepwise regression fitted pretty well and accurately described the relationship between each parameter and casing effect with the correlation coefficients (R2) of 0.988 9 for casing uniformity and 0.992 2 for effective utilization rate, respectively. Contribution rate analysis indicated that hot air temperature made the greatest contribution to casing uniformity with the contribution rate of 1.829 5, as did the velocity ratio of hot air motor to the effective utilization rate of casing with the contribution rate of 2.338 6. 2) The optimal casing parameters were hot air temperature 45.0 ℃, the opening of circulation air valve 45.0%, the opening of the exhausted valve 50.0%, the velocity ratio of hot air motor 70.0%, compressed air pressure for the nozzle 0.35 MPa. Production validation showed that casing uniformity coefficient and the effective utilization rate of casing reached 95.03% and 65.90%, increased by 2.60% and 5.80%, respectively comparing with the control.
