Secondary metallurgy at machine-building plants

Abstract

Metallurgical production in foundries of machine-building plants is characterized by a number of specific features due to a wide variety of products, particularly stringent requirements for the quality of the metal produced, as a rule, for a responsible purpose. Accordingly, the foundry of machine-building plants is equipped with the most advanced technological equipment of various types with wide technological capabilities. It is no coincidence that it was at machine-building enterprises that the main types of secondary processing units were first used. Therefore, the history and current state of secondary metal processing at machine-building plants needs to be studied in detail. The metal is refined both in preparation for casting and directly in the casting process. It should be noted that the foundry does not take full advantage of the available wide technological possibilities of modern refining methods, some of which are discussed in the article.
