Abstract

PURPOSE: To simply manufacture low sulfur ferroalloy of high yield by casting molten metal discharged from a refining furnace to a predetermined thickness without carrying out desulfurization and by spcifying the time and temp. for heat insulating the surface part of the cast metal.
CONSTITUTION: Molten metal discharged 2 from electric furnace 1 is cast into surface plate 3 to above 250mm thickness, and the surface of cast metal 4 is covered with heat insulating material 5 and kept warm with gas burner 5. At this time, the surface of cast metal 4 is regulated to above 800°C after 120min from the beginning of casting, followed by cooling. Thus, a metal layer (skin) contg. much sulfur segregated is formed at the surface part of metal 4, and by removing the layer low sulfur ferroalloy is obtd. in a high yield.
