Diffusion Processes Occurring During Production of Alloy Layer on Steel Cast Moulds

The paper presents the results of simulation tests with the use of the Thermo-Calc software. The effect of adding silicon to the alloy insert material on the process of its liquefaction was tested. The liquidus and solidus temperature of high carbon ferrochromium affecting the process was also determined. It has been found that the increased Si content causes reduction of the solidus temperature of FeCrC which causes the increase of the diffusing components and further leads to faster liquefaction directly related to production of the alloy surface layer.
