ABSTRACT
Purpose.Comprehensive assessment of metal-containing waste generation in steel rolling production and development of effective methods for recycling production by-products.
Research methodology. Methods were used to study the processes of scale formation depending on the mass, size, composition of the workpiece, and steel grade. The elemental composition of the studied scale samples was determined using an X-ray fluorescence spectrometer. Experimental studies were conducted on the quantitative and qualitative composition of the scale formed after the workpiece passed through the ring furnace.
Research results.The main aspects of scale formation and the amount of waste generated were determined, and the problems and ways of recycling metal-containing waste were analyzed. A comprehensive study of the quantitative and qualitative composition of scale was conducted, and the potential for using scale components as secondary resources was investigated. A model for the efficient use of waste and by-products of production was developed.
Scientific novelty.The methodology for assessing the volume and composition of scale formed in steel rolling production depending on the temperature and composition of the atmosphere, heating time and component composition of the metal, as well as the cooling rate of the billet, has been further developed.
Practical significance. The results obtained can be applied in research on the comprehensive processing of metal-containing waste from steel rolling production, reducing the negative impact on the environment, and reducing disposal costs. The proposed “Model for the efficient use of waste and by-products of production” provides support for the development of integrated processing technologies, prospects for greening and environmental protection in metallurgical enterprises.
Keywords: industrial waste, metallurgical production, scale, by-products of production, waste disposal.
