Our education proposal is characterized by new and pragmatic contents and methods. Our courses, in fact, consist of many hours devoted to trials and tests in foundry: about the 25% of lessons is dedicated to practical verifications in the field. Our purpose is quantifying and making objective the feelings of the metallurgist, often undervalued since a not so evident aspect of his daily work, in order to understand what are the most efficient actions to adopt in function of the qualitative status in a certain time. It is very important trying to minimize changes, even if accepting them as intrinsic part of the process; our objective, by training foundry men, is therefore showing them how to quantify these changes and how to manage them by standard tools and resources. Thus, for example, during the tests in the foundry, we demonstrate to trainees the importance of physical aspects of solidification (nucleation, increase in volume, thermal conductivity, primary precipitations, position in the phase diagram, etc...) and how these aspects can be affected by the common weapons in the hand of foundry men (the preconditioning, the ladle and stream inoculation, the nodularizing treatment, the recarburization, the skimming, etc...).
In this section are described all the training courses that we would be able to organize in at our premises or directly at the customer’s premises.
List of courses:
- Basic principles: knowledge of cast iron metallurgy.
- The physics of solidification.
- Structure of a cooling curve and analysis of critical parameters.
- Process control criteria.
- Base iron preparation. Fundamental differences with the chemical composition being equal.
- Preconditioning: quantifying its effect.
- Inoculation: quantifying its effect. Simulation of a hypo-inoculation and a hyper-inoculation.
- Spheroidization treatment: quantifying the results of Mg on the cast iron solidification. Forecasting of nodularity and thermal conductivity of cast irons.
- Stream inoculation: quantifying its effect. Management criteria and dynamic inoculation.
- Cast iron permanence: its effect.
- Pouring temperatures: their effect.
- Forecasting in real time of cast iron mechanical properties. Nodular, gray and vermicular irons.
- Case study 1: Change of melting furnaces charge materials at power frequency. Consequence on cast iron metallurgy and on shrinkages tendency the chemical composition being equal.
- Case study 2: Quick change of process parameters in a tricky casting prototyping phase. Negative aspects of hyper-eutectic and eutectic irons with high Carbon content.
- Case study 3: Process control completely grounded on thermal analysis of melting and pouring furnaces.
