Prediction of heat flow through sand mould and its verification on the structure and property of gray cast iron

Heat flows through the mould in casting govern the cooling rate of the liquid which affects the structure and properties of the materials. By controlling the heat flow direction, it is possible to control the structures as well as properties of the materials. To predict the heat-flow through the san...
