| Summary: | Many form of defect can found on the casting product such us inclusion, crack, blow holes and porosity. This type of defect can also found in machine block and cylinder head that made by grey cast iron. Beside the defect cause from casting process, the defects can also found on that component due to operational cycle. Surface defects or damages are allowed to repair. The surface defect can be repaired by liquid flow method. This method believed has many advantages in repairing gray cast iron component.
The successful of this liquid flow repair method depend on several parameters such as preheat temperature, pouring time, sand ratio, and the shape of the inlet and outlet. The first two parameters are absolutely influence the quality of repair result. To provide the good preheat temperature, the stove is needed to provide uniform heating on the repaired component with heat flow and fuel consumption can easy controlled.
The design, production, and testing of stove are done with the main purpose to provide good stove in heating of repaired component until preheat temperature is achieved. The result of testing on the stove to heat the specimen with size (275x275x15mm) give the same result with the numerical analysis which have done. The testing of stove can heating the specimen witch that size until 400 degrees C preheat temperature within 51.43 minute of heating time.
With the same modeling condition, simulation in numerical analysis is done using ANSYS v9.0 software for deferent size of specimen which has 25mm and 35mm thick. Based in the analysis result the preheat temperature that can be achieved are 400 degrees C in 118 minute of heating time for the specimen with 25mm thick, and 300 degrees C in 86 minute of heating time for the specimen with 35mm thick. |
