Steel recycling generates a small water impact. This impact is due to steel production from sources generating blast furnace slag which in turn is used in concrete production as a substitute for cement. When recycling is undertaken, this process no longer occurs, so concrete production must revert to cement in place of blast furnace slag.

Steps have been taken all over the world to generate new ways of recycling or to reuse slag material. Advances have made it plausible to separate metallic scrap and lime in the slag. Slag has been considered as an alternative for submerged arc welding flux and even used for construction materials.
The metal recycling process produces fewer emissions, and requires significantly less energy than producing new metal alloys. The ISRI factsheet for iron and steel shows that recycling steel requires 56% less energy than producing steel from iron ore. In addition, by using ferrous scrap rather than materials in the production of iron and ...

3 Iron Unit Recycling On a weight basis, steel is the most recycled material in use today (Figure 3-1). The 70 million net tons of steel recycled in 2000 were used to produce about 112 million net tons of new steel in the United States.
THE STANDARD Jaw crusher was specially designed for the slag recycling industry. It has the unique patented H ydraulic R elease M echanism to guarantee continuous crushing.No blockage when uncrushable materials like metal hit the crusher.
The recovered dust (Waelz oxide) is enriched in zinc oxide and is a feed product for zinc smelters, the zinc reduced by-product is known as Waelz slag. Sub-optimal features of the process are high energy consumption, and lack of iron recovery (and iron rich slag).
The Recycling of Materials Containing Iron and Zinc in the . of iron oxides and zinc in steel prevents it from being recycled in blast furnaces. A similar situation exist in regard to blast furnace slag, which contains not only iron and carbon (2530%) but also 1,5% zinc.

Recycling iron and steel slag. Steam aging facilities. In fiscal 2011, our Kakogawa Works and Kobe Works together generated 2.41 million metric tons of blast furnace slag and 1.11 million metric tons of steel slag as byproducts. Both types of slag are reused as a raw material for cement or as a bedding material in road construction.
RECYCLING OF STEELMAKING SLAG FROM ELECTRIC ARC FURNACE Ľ MIHOK1, K.SEILEROVÁ , D.BARICOVÁ Technical University, Faculty of Metallurgy, Letná 9, Košice, Slovakia SUMMARY The paper presents results of research of demetallized EAF slag recycling into charge of electric arc furnace. Effects of recycling on steelmaking process parameters,
In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and iron are formed.
Iron and steel slag refers to the type of metal manufacturing slag that is generated during the process of manufacturing iron and steel products. The term "slag" originally referred to slag produced by metal manufacturing processes, however it is now also used to describe slag that originates from molten waste material when trash and other ...
Jul 28, 2016· The recovered iron-rich products are recycled back into the ironmaking and steelmaking processes to replace high-cost steel scrap and iron ores. However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable “metallic” slag fines with ...

Air-Cooled Blast Furnace Slag. Crushed ACBFS is angular, roughly cubical, and has textures ranging from rough, vesicular (porous) surfaces to glassy (smooth) surfaces with conchoidal fractures. There can, however, be considerable variability in the physical properties of blast furnace slag, depending on the iron production process.
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 …
Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
