摘要
为了解决三乙胺冷芯盒砂芯(以下简称冷芯)存储时间过短和存储强度过低的问题,对恒温恒湿库和中试车间这两种不同环境条件下的冷芯强度进行了研究和分析,运用minitab软件对冷芯的存储效果进行模拟,得到线性回归模型,运用试验优化设计最终得到温度20℃、相对湿度10%的最佳的工艺组合,使冷芯强度从1.05 MPa提高到1.57 MPa,节约了存储空间和不必要的存储成本。目前最优工艺设定已经在公司内部得到了推广应用,效果明显。
In order to solve the problems of short storage time and low storage strength of sand core of phenolic urethane cold box process,the strength of constant temperature and humidity storehouse and pilot plant was studied and analyzed in detail,and the storage effect was simulated and optimized by using experimental optimization design and Minitab software,and the linear regression model was obtained to find the best combination of temperature and humidity,so as to make the constant temperature and humidity storehouse more effective.The optimal value prediction used the experimental optimization design to finally find the best process combination with temperature of 20℃and relative humidity of 10%,improving the cold core strength from 1.05 MPa to 1.57 MPa.At present,the optimal process setting has been promoted and applied to the company,and the effect is obvious.
