Once it is melted and the temperature rises to around 2800 degrees Fahrenheit, it is transferred to a treatment ladle where magnesium compounds are added to produce the spheroid nodules needed to form ductile iron. Impurities are then removed in an operation referred to as slagging, a sample is collected, and the batch is transferred to the automatic pouring ladle. From the control room, an operator monitors the functioning of the Auto-Pour as well as the time, temperature, and level of the iron. The entire molding / pouring process is choreographed by computer controls to produce consistent pours while reducing waste. |
