| Abstract: | The phenomenon of the copper alloy penetration into mould (core) in large casting has been investigated by the simulated laboratory equipment, in which the permeability of mould (core) sample can be controlled . The following conclusions have been reached: When the mould (core) temperature is equal to the copper liquid temperature and the mould (core) permeability is higher and there is a higher pressure of the liquid metal, the penetration will take place. The penetration is stopped by using fine chromic iron sand. |
