The integration of ferroalloy smelting with slag production also provides advantages in terms of process efficiency. This would include recycling or sale of highvanadium pig iron and reuse of spent basic slag. V. Research and New Zealand Steel Ltd.

For most ferroalloy producers, slag has limited or no value after the smelting process is completed. In many cases, slag management represents an increasingly expensive handling and storage challenge. Slag has untapped potential as a source of energy, revenue (from highvalue slagsales) and unrecovered alloy droplets.

deliberately produced in a production process." A production residue may be considered a byproduct if it possesses characteristics that make it ready for further use in the economy; its further use must be a certainty without any further processing . • A byproduct is a secondary product derived from a manufacturing process or chemical ...

Steelsmelting slag is used in the production of gravel for road construction; in sintering blast furnaces and cupola furnaces it is used to extract the manganese, iron, and calcium oxide present in the slag. Ferroalloy slags are processed into ground limestone, gravel, and slag sand for construction as well as a powder used in foundry production; a portion of such slags is used in the production of alloys.

Electric arc furnace carbon steel slag is a byproduct of the manufacture of steel by the electric arc furnace process (EAF). Production and Processing An EAF produces steel by the melting of recycled steel scrap, using heat generated by an arc, created by a large electric current.

Jan 01, 2014· The Complete Book on Ferroalloys. The production of a particular ferroalloy involves a number of processes to be followed in order to give the alloy desired physical and mechanical properties. The slight difference in the temperature or heating or composition can lead to entirely different alloy with different properties.
