Numerical simulation of unidirectional solidification on ingot of heavy plate based on MARC

Unidirectional solidification technology is a producing process of cast large-sized ingots industry and control the single orientation microstructure of solidification. Combined with the conditions of production, casting the 23t ingot of unidirectional solidification for experiment, we made numerical simulation of the 23t unidirectional solidification ingot with MARC; these are consistent with the result of experiment, and testified the simulation is feasible, offered gist for the design of the mould and casting, and took on reference to the product field.
