ANALYSIS OF CASTING QUALITY PARAMETERS OF GRAY CAST IRON UNDER THE INFLUENCE OF MODIFIERS

One of the important tasks in the world today is to obtain high-quality, inexpensive thin-walled cast products based on increasing the strength, quality, mechanical and operational properties of parts used in the mechanical engineering and manufacturing industries obtained by casting. In addition, the need for lightweight products with high strength is increasing to reduce energy and fuel consumption. As a result of the increasing demand for thin-walled cast products in the world, many techniques and technologies have been developed, requiring the production of high-quality, inexpensive and competitive parts from them. For reference, in 2021, gray cast iron had the largest market share in the global steel and cast iron production market, accounting for 37% [1].
