Abstract: In this paper, by using the commercial finite-element software of ProCAST, unidirectional solidification processes in 23t steel ingot were simulated. Emphasis is placed on analysis of required time for complete solidification of steel ingot and temperature distribution about ingot and side wall during the solidification process. By comparing simulation values and measured values of side wall during the solidification process, the simulated results conclusively demonstrate that our developed model is feasible and valuable.

Abstract: 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.
