| 摘 要： | 为确定呋喃树脂砂的合理吃砂量,研究了以硅砂为原砂制备的呋喃树脂砂在100～500℃内的溃散性,确定了型砂全部溃散时的最低温度为350℃；然后,运用ProCAST软件模拟了不同壁厚的圆筒形铸铁件的凝固过程及铸型和型芯的温度场,并研究了圆筒形铸铁件壁厚(模数)与呋喃树脂砂临界吃砂量的关系,最终得到了两者之间的回归方程.

| Abstract: | In order to determine the rational mold thickness,collapsibility of the furan resin sand made from the silica sand between 100 and 500 ℃ was researched and the lowest temperature of 350 ℃ at which the mold fully collapsed was found out.Then,the solidification process of cylindrical iron casting with different wall thickness and the temperature field of the mold and core was simulated by use of the ProCAST.And the relationship between the wall thickness(module) of the cylindrical iron casting and the critical mold thickness of the furan resin sand was investigated;at last,the regression equation between them was obtained. |
