Originální abstrakt
This paper deals with theoretical analysis of burn-on and penetration defects in steel castings. These defects are principally caused by local overheating of the sand mould or cores. Such overheating can cause liquid metal to strike at the mould surface and entrain onto the surface of the mould. A method has been described to predict likely burn-on and penetration defect locations as part of a standard casting simulation. The method is based on determining, from simulation results, the locations where the mould is above a certain critical temperature. The critical temperature is generally above the temperature at which the steel is fully solidified. By measuring the time periods during which these locations in the mould are above the critical temperature, burn-on and penetration defects can be predicted.
