In electric arc furnaces, a combination of scrap iron, steel, and scrap substitutes are placed in a furnace and melted by the use of heat produced from an electric current. A lime flux consisting of quicklime or a blend of quicklime and dolomitic lime is added. The total flux amount will vary based upon the steel type and quality to be produced. The lime flux removes impurities and forms a slag that can be separated from the steel and poured from the furnace as a liquid. It also reduces refractory wear and gunning and can provide a foaming slag for long arc operation.
Mississippi Lime’s Standard Quicklime products are widely used due to their exceptional quality and consistency. High available calcium oxide, low total sulfur levels, low impurities, low loss on ignition and controlled fines content allow Steel companies to cost effectively meet the high quality standards required in today’s global market place.
