USE OF A DEVELOPED PRODUCTION PROCESS OF CENTRIFUGAL ELECTROSLAG CASTING FOR MANUFACTURING A REDUCER

摘要

A production process is considered for preparing reducer-type objects from steel grades 17G1S and 09G2S by centrifugal electros lag casting. Analyses of chemical composition and mechanical properties are provided for objects prepared by different technology. The advantage of centrifugal electroslag casting is demonstrated, making it possible to prepare cast objects with physical and mechanical properties corresponding to the State Standard (GOST) and technical specifications for these steel grades having configuration and geometric dimensions close to those of finished objects.
