| Abstract: | In this paper gray iron plug was produced by the fusible pattern moulding. The gating system was designed by using the proportional solidification technique and the process of pouring was controlled strictly in order to avoid the oxidizing slag flowing into mould cavity. As a result, the blowholes were removed effectively. By means of regulating the density of sodium silicate and the power-to-liquid ratio of the mixture of dressing and standardizing the dwell process, the surface coarseness of the holes that were in the casting was improved. |
