Development of Electroslag Metallurgy in China

摘要

The electroslag metallurgy in China has been developed since 1958 and industrialized since 1960. At present time, there are about 100 industry electroslag remelting (ESR) furnaces and many small ESR furnaces allover the country with annual capacity of 150,000 tons. The products remelted by ESR include 243 designations of alloying steel and superalloy. The Chinese metallurgists have made significant achievements in the type and structure of furnaces, electroslag remelting technology, the manufacture of large-size ingots by ESR, near net shaped casting by electroslag casting (ESC), the electroslag crucible melting (ESM), centrifugal induction electroslag casting (CIESC) and the study on the behavior of inclusions during the ESR process. These achievements have already been recognized by foreign metallurgiests.
