• Minerals | Special Issue : Metallurgical Slags

     · However, these processes are accompanied by the production of a variety of byproducts with metallurgical slag being one of the most important. Metallurgical slag is formed during the smelting of metallic ores and can be considered as an equivalent to igneous rocks because it is composed of synthetic analogues of silies, oxides and sulfides, usually occurring in rocks.

    slag compositions that are liquid at 1500 °C. Outside this area the slag is either solid or a mixture of solid and liquid. Amount of solid depend on slag composition and temperature. In HCFeCr production, the slag temperature is normally assumed to be between 1600 °C and 1800 °C, depending on operational procedure and ore type.

  • Basics of slag production

     · Slag from the production of ferrochrome is also included here; this material is produced in substantial tonnages and the main use of ferrochrome is in the steel industry. Slags also arise from other processes, particularly the smelting of nonferrous metals, but these materials can be very different and each needs to be studied individually.

  • High Carbon Ferrochrome Technology

     · Alloy is tapped at intervals equivalent to 70 to 90 t of alloy production. Alloy is tapped until the slag appears from the alloy tap hole. The furnace alloy level is managed by adhering to a regular tapping schedule (2 taps per shift) and the procedure of tapping alloy continues until the appearance of the slag.
