Jan 10, 2014· Slag use is subject to strict regulations and standards. The use of slag is clearly regulated for particular applications. For instance, production of aggregates is carried out in accordance with the European Construction Product Directive and harmonized, European standards: EN 12620/aggregates for concrete
(SiO2), hematite (Fe2O3), manganese (III) oxide ... Hence use of coarse electric arc furnace steel slag aggregate in production of WMA mixture is recommended. View Show abstract.
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.
The structure of hematite is hexagonal and that of magnetite is BCT or inverse spinel. During reduction, the phase change in hematite takes place at a temperature of 500 deg C. This change brings with it an increase in the volume thereby increasin...
Even though there is evidence of iron production in crucibles already in ancient times, reduction of lump ores by charcoal was used for its practical use at the beginning of iron industry. Charcoal provided necessary heat and reducing gas. Reached temperature did not exceed 1000 °C. The product was a conglomerate of reduced iron and slag.
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel. The common ores of iron are both iron oxides, and these can be reduced to iron .
Primary Metal Production Pyrometallurgy deals with chemical reactions at high temperatures (ranging from 100°C up to 3000°C). These reactions involve numerous different solids, liquids, and gases, and are carried out using many diverse types of furnaces.
plants often use a mix of DRI and recycled steel feeds. On average the production of one tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of co-products. These include slags, dusts, sludges and other materials. Ironmaking and steelmaking slags More than 400 million tonnes of iron and steel slag is produced each year.

In the electric-furnace production of pig steel from ore, carbon in the product can be kept below 2.2 per cent., and regulated to an extent by the amount of carbon charged, without resulting in excessive loss of iron in the slag or in the production of a pig steel very high in impurities, if a fair grade of ore is used.
Mobarekeh steel company is the largest steel producer of and produces around 600t of EAF slag per year. The slag produced in this plant normally cools in the air, but the mineralogical composition can be adjusted by appropriate cooling methods in order to fulfill the mineralogical requirements of cement production.
