New Possibilities of ESR for Modern Machine Engineering

摘要

Electro-slag re-melting (ESR) is a process that combines all important elements of steel melting conversion. JSC “RPA “CNIITMASH” continuously developed ways to use ESR to manufacture critically important parts for power engineering, including nuclear power engineering, heavy-duty machine engineering and other machine building industries. Enhanced performance of product is an important competitive advantage that ESR provides in comparison to other metallurgical processes. Present report reflects results of the latest research work aimed at resolving issues related to control and management of refining and crystallization processes, cost reduction for ESR products. Practical relevance of developed approach to control of ESR metal quality is revealed by data of achieved parameters which characterize properties of pipes and pipeline elements in energy and nuclear power industries which rely on ESR ingots as work-piece blanks.
