支撑座铸钢件的铸造工艺及其优化

摘要

对支撑座铸钢件进行了铸造工艺设计。综合考虑铸造性、经济性及缺陷情况，选择了较合理的铸造方案。通过CATIA软件对该支撑座、浇注系统及冒口、冷铁和保温套进行了三维建模。借助ADSTEFAN数值模拟软件对支撑座充型过程和凝固过程分别进行了模拟。根据模拟结果优化冒口、冷铁和保温套的位置、尺寸和形状，从而改善了支撑座的凝固顺序和铸造质量。%casting process for cast steel support seats was designed. Relfecting on castability, economy and defects, a more reasonable casting process was selected. The support seat, gating and riser, and chill and insulating sleeve were 3-D modeled by CATIA software. Cavity ifll process and solidiifcation process of the support seat were numerically simulated by means of ADSTEFAN software, respectively. Based on the simulated results, location, size and shape of the riser, chill and insulating sleeve were optimized, thus improving the solidiifcation order and casting quality of the support seat.
