Technology for prevention of ports in castings

In this paper the statistical analysis is aimed to optimize process parameters at the case study, i.e. To minimize major steel casting defects of production plants. This project is intended to observe just two of the steel casting defects which are severe in their nature i.e., gas defects and shrinkage defects. In order to minimize these defects, four process parametrs were studied like Sand-binder ratio, Mold permeability, pouring temperature and De-oxidant amount in three levels. In order to obtain a representative experimental data it was used a factorial experiment. The relative influence of each factor on the casting defect/porosity was determined and suggestions have been given using the Statistical analysis method by optimizing the process parameters.
