Developing a concept for recycling byproducts generated during re-melting of secondary metals in order to meet the needs of supplying industries (i.e., those industries which supply products, articles and components for further use by other industries) is one branch of research (among others) of the Chair of Foundry-Metallurgical Processes and Alloys at Nizhny Novgorod State Technical University named after R. E. Alekseev.

Within the framework of this branch the problem of recycling the slag generated during aluminum scrap re-melting (aluminoslag) is being solved. This slag is abundant at the enterprises of secondary metallurgy, as well as at the foundry shops of the machine-building, automotive, tool-making and instrument-making industries. In particular, one of the possible ways of recycling of this aluminoslag is its application as a filler in anti-penetration coatings for foundry molds and cores in steel and iron casting.

The suggested development has passed industrial approbation with a positive economic effect at Nizhny Novgorod Machine-Building Plant Ltd. and several other plants of the city of Nizhny Novgorod. Over thirty scientific papers have been published, one degree of PhD (metallurgical engineering) has been earned, one Russian patent for an anti-penetration coating filler has been taken out on the base of results obtained by this work.
