Gypsum casting powder for precision casting of aluminum alloy and preparation method of gypsum casting powder
The invention aims to provide a gypsum casting powder formula for aluminum alloy precision casting and a preparation method thereof, and belongs to the technical field of casting, the gypsum casting powder comprises the following raw materials by weight: 35-45 parts of gypsum powder, 30-40 parts of bauxite, 10-15 parts of quartz sand, 5-10 parts of diatomite, 5-10 parts of gypsum whisker, 0.5-1 part of fiber, 1-3 parts of a heat conduction agent, 0.3-0.5 part of a water reducing agent, and 0.1-0.4 part of an antifoaming agent. The invention further discloses a preparation method of the gypsum casting powder for aluminum alloy precision casting. The gypsum casting powder for precise casting of the aluminum alloy is high in stability and simple in preparation process, the prepared gypsum casting mold line is low in shrinkage rate, high in strength and small in crack generation tendency, and an obtained formed casting is high in size precision and good in surface quality.
本发明的目的在于提供一种用于铝合金精密铸造的石膏铸粉配方及其制备方法，属于铸造技术领域，该石膏铸粉中各原料的重量份数分别为：石膏粉35～45份、铝矾土30～40份、石英砂10～15份、硅藻土5～10份、石膏晶须5～10份、纤维0.5～1份、导热剂1～3份、减水剂0.3～0.5份、消泡剂0.1～0.4份。本发明还包括所述一种用于铝合金精密铸造的石膏铸粉的制备方法。本发明的用于铝合金精密铸造的石膏铸粉稳定性强、制备工艺简单，制得的石膏铸型线收缩率低、强度高、产生裂纹的倾向小，所得成型铸件的尺寸精度高、表面质量好。
