The results are very important to understand the solidification characters of steel castings with T conjunction and to estimate the position of the hot-spot in the castings to avoid shrinkage defects.
得到有益于认识铸件中此类接头凝固特性和热节位置的变化规律,对工艺设计者认识和防止成型过程中产生凝固收缩缺陷是很必要的。
According to the simulated temperature fields and solid fraction, the hot spot and shrinkage porosity are not found in the bolster casting, so the new casting process is feasible.
温度场和固相分数的模拟结果表明,铸件没有产生热节和缩孔缺陷,表明了新工艺的可行性。
An analysis of quality problems such as skin is not smooth, shrinkage, hot spot and influencing factors.
对包子的质量问题如表皮不光滑、皱缩、烫斑和影响因素进行分析。
The results indicate that the casting defects are mainly shrinkage porosity and cracks caused by solidification shrink, which mainly presents in the hot spot between the spoke and the rim.
研究表明:轮毂的工艺缺陷主要为缩孔、缩松以及凝固过程中收缩导致的裂纹缺陷,主要分布在轮辋、辐条交汇的热节部位。
