- 摘要:
- 利用ProCAST软件对大型铸钢支架进行充型和凝固模拟，分析冒口与冷铁的数量和位置对铸件缩松缩孔 分布的影响。 通过模拟结果优化底注式铸造工艺，逐步使缩松缩孔缺陷从铸件转移到冒口内部，将缩松率降到最低，保 证铸件的致密性，得到高质量的铸件。ProCAST software was used to simulate the mold filling and solidification of large cast steel support, and the influence of the number and position of riser and chiller on the distribution of shrinkage cavity and porosity was analyzed. Through the simulation results, the bottom injection casting process is optimized to gradually transfer the shrinkage cavity and porosity defects from the casting to the riser, and finally the shrinkage cavity rate is reduced to the minimum, so as to ensure the compactness of the casting metal and obtain high-quality casting.
