MODIFICATION OF FOUNDRY ALLOYS AS AN EFFECTIVE RESERVE FOR INCREASING THE STRENGTH OF LRE CASTINGS
An effective technology for modifying high-strength corrosion-resistant foundry steels is developed at NPO Energomash. Such technology has made it possible to improve the quality of casting and the level of mechanical properties of VNL-1, VNL-6 and VNS-25KL steels. The developed technology includes metal smelting in open induction furnaces using a modified charge of electroslag remelting supplied by the Elektrostal plant. For development of this technology, use of modified electroslag charge is recommended to increase the strength of castings of heat-resistant nickel-based alloys.
