Abstract
Problem Statement (Relevance): This paper is concerned with an urgent problem of industrial waste utilization. The authors show that in some cases the utilization of industrial waste results in a considerably reduced final product cost. It was found that the application of industrial waste can have a positive effect on the quality of some of the materials used in the foundry industry. Objectives: The objective is to draw the attention of the academic community to the environmental problems caused by industrial sites and to demonstrate that the application of industrial waste can improve the quality of moulding materials applied in foundry industry while reducing the cost of the final product. Methods applied: This research is based on the standard methods of analyzing the physical and mechanical properties of moulding materials used in foundry industry. Originality: The originality of this research includes enhanced chemical compositions of moulding sand mixtures used to produce foundry moulds, cores and heat insulating covers, which include extrusion starchy agent, tripoli powder, flue ash from heat power-stations, haydite dust, slag from non-ferrous and ferrous metallurgy etc., all of which are the types of industrial waste. Practical Relevance: The authors show what practical value the industrial waste can have in the foundry industry. This includes a partial utilization of industrial waste, an improved quality of the foundry materials, reduced casting costs and an enhanced quality of castings. It was established that the use of waste products has a great potential in the development of new materials and that further research in this area can boost the national economy.
