Subject aims expressed by acquired skills and competences
The student will be able as follows:
- to know the bases of foundry technology and the types of forming wastes;
- to classify foundry waste according to its volume and danger degree;
- to analyse possibilities of secondary utilization of foundry wastes (moulding mixture, slag, dusts, refractory materials);
- to choose the most suitable method of moulding mixture reclamation according to the binder system;
- to evaluate conditions of waste recycling from dedusting systems
