| description | The invention discloses a method for eliminating local hot spots in gypsum mold casting, which belongs to the technical field of casting and comprises the following steps: arranging a chilling layer on the surface of a gypsum mold at the hot spots of a casting; according to the invention, the final solidification area of the T-shaped section can move towards one side of the metal mold, so that the feeding performance of the arc of the hot spot is improved, and the shrinkage porosity defect of the hot spot is reduced.
本发明公开了一种消除石膏型铸造局部热节的方法,属于铸造技术领域，包括在铸件热节处的石膏型表面设置激冷层；本发明可以使T型节最后凝固区域向金属模一侧移动，提高了对热节圆弧处的补缩性能，减少了热节处的缩松缺陷。 |
