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.
