Original abstract

This paper presents the results of the investigation of new hydraulically setting binders in foundry moulds with contact of liquid grey cast iron. These binders based on alumina and Portland cements are environmentally friendly and exhibiting admirable performance. Methodology of trials was designed and its attestation was implemented in experimental and working conditions. In the interface between cement sands and liquid metal were certified generation of complex allied substances – on the base Si, Fe, Al and Ca. In many cases FeS has been found. All these compounds are illustrated by SEM microscopy. The mathematical model of mechanical penetration has been created and proved influence of the temperature and chemical composition of grey iron on the range of penetration in the experimental moulds. The research and development of these inorganic binders for the foundry use will be the solution for future no waste technologies.
