Subject aims expressed by acquired skills and competences

Student will able: to know the rules for using quartz and non-quartz base sands; to know processes of the cooling effect control of a foundry mould; to explain kinds and importance of base sands surfaces and principles of their measurements; to know types and means for reclamation of foundry base sands; to analyze physical and chemical nature of binding property and strength of moulding mixtures; to explain principles of classification of binder systems of the Ist up to IVth generation; to design a binder system for the given technological process of casting manufacture; to explain physical principles of binding the mixtures of the IIIrd generation; to describe chemical hardening processes of inorganic and organic binders (condensation, polymerization, addition, copolymerization). Knowing the process and methodology of complicated and time-consuming tests evaluation sand and bentonite mixture based on visual methodology
