Abstract
The solidification process of steel ingots is simulated with an aqueous solution of NH4Cl-H2O system.
The temperature distribution in ingots during solidification and the laws governing solidification process is studied with the solidification experiment of NH4Cl-H2O system, The resulfs of the experiment generally conforns to the theoretical calculations.
Both the fluid flow pattern in the simularing mould and the formation process of the channels of macro-segregation are observed adopting colouring method. Meanwhile,the conclusion is reached that the utilization of Argon-blowing into the mould may affects the structure of the 2-phare zone and the formation of the Segregation channels.
