摘　　要： 采用四元二次回归正交旋转试验和响应面分析方法,利用SPSS11.5和Matlab7.1软件研究成型压力、加热温度、花生壳含水率和花生壳与粘结剂质量比对花生壳成型块松弛密度的影响,建立了花生壳成型块松弛密度的数学模型,得出花生壳成型块的最优松弛密度。结果表明:对花生壳成型块松弛密度的影响次序为成型压力、加热温度、花生壳与粘结剂质量比、花生壳含水率;最优组合为成型压力10 MPa,花生壳与粘结剂质量比3∶1,花生壳含水率15%,加热温度100℃,此条件下得到的花生壳热压成型块的松弛密度为1.100 8 g/cm3。 Based on the quadratic regression orthogonal rotation tests on four factors and response surface methodology,a study on the influence of briquetting pressure, heating temperature, moisture and the ratio of peanut hull to binder on briquetting relaxation density was performed. Mathematical models of briquetting laxation density were established and analyzed by using SPSS11. 5 and Matlab7. 1. The results show that the sequence of four factors influencing on relaxation density is as follow briquetting pressure,heating temperature,ratio of peanut hull to binder and moisture. When the briquetting pressure is 10 MPa,the ratio of peanut hull to binder is 3 ： 1 ,the moisture is 15% ,and the heating temperature is 100%, the optimum conditions appears. Under this conditions, the briquetting relaxation density is 1. 100 8 g/cm3 ,which meets the requirement of briquetting.
