摘　　要： 采用四元二次回归正交旋转试验和响应面分析方法,并利用SPSS 11.5和Matlab 7.1软件研究了成型压力、加热温度、含水率和粘结剂添加量对稻壳成型块松弛密度的影响,建立并分析了稻壳成型块松弛密度的数学模型。结果表明,4个因素对稻壳成型块松弛密度影响次序为:加热温度、含水率、成型压力、粘结剂添加比,最优组合为成型压力10 MPa,粘结剂添加比3.5∶1,含水率16%,加热温度100℃,此时成型物松弛密度为0.945 g/cm3,该密度可以满足成型要求,所得回归方程显著,拟合情况良好。 In order to develop the rice hull hot briquetting technology and machine,the effect of briquetting pressure,heating temperature,moisture and the ratio of rice hull to binder on briquetting laxation density was studied based on the quadratic regression orthogonal rotation tests with four factors and response face method.Functional models of briquetting laxation density were established and analyzed by SPSS 11.5 and Matlab 7.1.The results showed that the effect order of four factors was as follows： heating temperature,moisture,briquetting pressure,and ratio of rice hull to binder.When briquetting pressure,ratio of rice hull to binder,moisture,and heating temperature were 10MPa,3.5∶1,16%,and 100℃ respectively,the optimum conditions were obtained and the briquetting laxation density reached to 0.945g/cm3,which was suitable to briquetting.The regression equation was significant,and the mathematical model for the simulation was presented.
