steel slag produce

Slag Wikipedia

Slag is drawn off the furnace just before the molten steel is poured into ladles for ingotting. Ferrous and non-ferrous smelting processes produce different slags. The smelting of copper, lead and bauxite in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags.

Steel Slag an overview ScienceDirect Topics

Steel slag is an industrial byproduct obtained from the steel manufacturing industry. It is produced in large quantities during steel-making operations that use electric arc furnaces. Steel slag can also be produced by smelting iron ore in a basic oxygen furnace.

Basics of slag production Article on the slag industry

Slag, as the term will be used here, is any siliceous melt that arises in significant quantity from the various processes used in the production of iron and steel, and more particularly the solid materials that forms when such melts cool. 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.

Ferrous slag is the by-product of iron and steel manufacturing. It arises from the conversion of ores to iron, hot iron to steel, from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel. Each year, about 45 million tonnes of ferrous slag (iron and steel slag) is generated in Europe. Examples of traditional applications of ferrous slag are the use as

Steel slag is used as raw material for blast furnace cement. Compared to mixed cement, blast-furnace cement offers the great advantages of increased durability (high resistance to seawater, reduction in alkali-aggregate reactivity, etc.) and enhanced long-term strength, along with lower CO2 off-gassing.

How is Steel Produced? World Coal Association

The most commonly applied process for steel-making is the integrated steel-making process via the Blast Furnace Basic Oxygen Furnace. In the basic oxygen furnace, the iron is combined with varying amounts of steel scrap (less than 30%) and small amounts of flux. A lance is introduced in the vessel and blows 99% pure oxygen causing a temperature rise to 1700°C. The scrap melts, impurities are
