ON THE ROLE OF FERROALLOYS IN STEELMAKING

2015-2-27  Manganese was thus used for steel deoxidation. Also the beneficial effect to avoid hot shortness by binding excess sulphur was soon recognized. Spiegeleisen containing 8-15 % Mn and ~5 % C was produced already in the 18th century in blast :furnaces. Mushet was also one of those who developed first ''tool steels" with 1-2 % Mn in 1860s.

The Smelting of Manganese Carbonate Ore

2010-1-5  Manganese oxide ores have traditionally been the principal source of supply for alloy smelting. At the beginning of the 20th century, the main suppliers were Georgia, India and Brazil. As the steel industry expanded, so also did manganese ore mining activity and the acceptance of ores containing less than 50% Mn. The steelmaking centres of the world by 1910 were Western Europe (principally

Manganese - USGS

Manganese is an essential element for modern industrial societies. Its principal use is in steelmaking, where it serves as a purifying agent in iron-ore refining and as an alloy that converts iron into steel. Although the amount of manganese consumed to make a ton of steel is small, ranging from 6 to 9 kilograms, it is an irreplaceable component in the production of this fundamental material.
