Technology for manufacturing molding and core mixtures for producing synthetic cast iron

The article presents the technology for manufacturing molding and core sands for producing synthetic cast iron, and also describes the scheme of the molding - pouring line. The composition and properties of core mixtures are reflected. Shows the process of preparing the molding sand using a mixing runner. The relevance of the topic lies in the fact that the increase in cargo transportation in the world places increased demands on cast iron used for the manufacture of railway parts and sets new challenges in the field of metallurgy, while reliability and durability are the most important of them. The fulfillment of these requirements determines the competitiveness of products in the corresponding segment of the railway transport market.
