| Abstract: | The effect of gas-forming property and decomposition latent heat of the polystyrene material on the molten metal flow velocity and the gaseous pressure of the gap in Lost Foam Process has been studied by means of numerical simulation.The results show that both gas-forming property and decomposition latent heat of the polystyrene material influence the metal flow velocity and the gaseous pressure of the gap significantly. |
