| Aims of the course unit:
|
The aim is to obtain the knowledge about metalurgy and foundry of ferrous and non-ferrous materials.
The subject gives the knowledge about metalurgy and foundry of iron and non-iron materials. In each of these technologies is the attention devoted to the kind of raw materials, semi-product, melting furnaces, machinery, quality and control of processes and also to the final product. The graduate obtains an orientation in the present production technologies of metals and alloys. |
