Continual improvement of product quality has been a long challenge to Semi-Solid Metal(SSM) technology. By conventional semi-solid processes, this might be attained at the expense ofeconomical production. The advent of Inclined Cooling Plate (ICP) process has already realized thedevelopment of non-dendritic SSM while satisfying qualitative, quantitative and economicalrequirements collectively. In spite of its potential advantages, functional mechanisms of this processare not yet clearly understood that makes its optimal utilization obscured.Basically, such understanding needs a picture of the process. As the first step, this picture is pursuedthrough physical modeling of the ICP process i.e. direct observation of an analog system by virtueof transparent character of a model alloy (succinonitrile-acetone). Based on this phenomenologicalmodel, a picture of the process is presented as follows: flowing molten alloy down ICP, multipleregions form typically on the plate i.e. a chilled layer at the vicinity of the plate surface, a two-phasemushy zone on the chilled layer and ambient liquid far from the plate surface. In this process,interaction of the liquid forced-flow with mushy zone separates solid particles from the stationarymush on the plate resulting in a two-phase mixture which is responsible for the formation of slurryi.e. SSM
