- Abstract
Ceramic and refractory materials are needed in many fields of activity, necessary for the development of human society, such as steel, non–ferrous metallurgy, chemistry, construction. The raw materials for obtaining refractory products are in short supply on the world market. In the activity carried out by leading economic agents, significant quantities of refractory waste are continuously generated, which must be neutralized and efficiently utilized. In this paper, the authors present the results of experimental research aimed at finalizing a technology for recycling mulcorite waste generated by an economic agent producing porcelain products. The physicochemical characteristics of this type of waste were determined and several technological variants of using mulcorite waste were tested, after an initial processing, in the manufacturing recipes of some pieces of refractory material component of the cast iron casting network from a manufacturer of gray iron castings. After testing eight variants of the composition of the manufacturing recipes, the best variant was chosen, which ensures the use of a maximum percentage of waste but also good values of the quality properties of the products obtained. For this, the main qualitative properties of the finished products were determined by measurements in the laboratory for the absorption coefficient, density and porosity, as well as by optical microscopy investigations on the structure of the finished products. The results of the conducted research demonstrated the possibility of efficient utilization of mulcorite waste, with beneficial effects on manufacturing costs and the environment.
