model and in a series of unique algorithms, based on the non- steady method of 3-D finite elements. Tese algorithms provide access to highly accurate results at every step in the process, from the turbulent liquid state through to the completely cooled solid state. Interactions between the solidifying alloy and its environ- ment, the mold’s various components, the ambient air, etc., are all perfectly reproduced by the solution. Users thus benefit from numerous advantages. For the con-


tinuous casting process, for instance, the solution can be used to: • simulate the ingot mold, rolls and sprays. • simulate the shape of the nozzle’s jets. • optimize the casting speed. • prevent cracks and ruptures. • optimize the ingot mold and the cooling. • control small faces. For the ingot casting process, the solution includes a number of specific features that can be used to: • prevent air gaps. • prevent cracks. • simulate exothermic powders. • predict the shape of the ingot. • optimize the strip out time. • predict segregation phenomena. • analyze the microstructure. THERCAST® also benefits from a cutting-edge IT so-


lution. With its very considerable parallel processing capac- ity, it can simultaneously exploit the power of an unlimited


确的结果。合金凝固过程与周围环境之间的相互作 用,模型各组成部分,大气等都能完美的模拟实现。 因此,使用连续铸造工艺的用户可从软件中获得很 多好处。例如,软件可适用于: • 模拟钢锭模,轧辊和喷涂, • 模拟喷嘴射流的形状, • 优化浇注速度, • 防止裂纹和断裂, • 优化钢锭模的冷却, • 细微环节控制等,


在铸锭的过程中,该解决方案包括了许多特殊功


能: • 防止空气间隙, • 防止裂纹, • 模拟涂敷放热粉末, • 预测铸锭的形状, • 优化出型清理的时间, • 预测偏析现象。 THERCAST®也得益于尖端的IT解决方案。其相当 大的并行处理能力,可以同时利用的数量众多功能强 大的核心处理器。所采用的增设附加磁芯技术提供了
