Hiroshi Yamagata, in The Science and Technology of Materials in Automotive Engines, 2005. 5.3.2 Analysis of chemical composition of cast iron before pouring. Reusable raw materials, such as steel scraps from the body press process, are an abundant by-product of car manufacturing (Fig. 5.10).An electric furnace 6 melts the scrap with carbon (to raise carbon concentration) and ferro-alloys.
Waste Disposal and Recycling in Steel Industry Steel is a versatile commodity that plays a major part in everyday life—from food cans, containers, automobiles, and office buildings. Steel makes up the largest category of metals in the municipal solid waste (MSW) and industrial waste streams.
Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes. Ferrous slag forms as a dominantly calcium silicate melt that floats on top of the molten ...
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.

slag industry. Additionally, slag is a sustainable (green) material that can be reclaimed and reused multiple times. Using iron and steel furnace slag will help preserve our natural resources. Based on numerous environmental tests, studies and reviews by governmental agencies and the iron and steel industry, we know that iron and steel slag is a
The difference was between adding steelmaking slag, FeO, or metallic iron to artificial seawater on sulfides has been investigated (Hayashi et al., 2014). In the case of slag, Fe in the slag reacted with the sulfide irons to form sulfides of iron, known as troilite (FeS) and pyrite (FeS 2).
May 24, 2018· During iron melting, the scrap material is exposed to high temperature and oxygen. Consequently, oxides are formed on the surface as a more or less viscous layer that can be removed. Slag is mainly a collection of compounds such as SiO2, Al2O3, Cao, FeO, MgO, MnO but can entrap cast iron droplets.
Slag contains reusable lime and metallic scrap that can be reused, in addition, being able to completely recycle it will save on cost of fuel, dumping, and transportation. The company STEIN Injection Technology developed a way to separate lime for the scrap and convert it in to usable wire injection that can once more be used to create clean steel.

Steel and iron slag Oxide dusts, sludges, scales, slags and spent refractories are co-products of the iron and steel manufacturing process. These residues generally represent 6-7% of the whole steel production. Their production arises from the conversion of ores to iron, hot iron to steel, and from melting scrap in an electric arc furnace or from the subsequent treatment of crude steel.
Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace.
We create a wide range of eco-products from the by-products of the steel production process and other industries. Some of our products, like metallurgical additives and refractories can be utilized on our steel customers' sites, while others are utilized in other industry applications like asphalt, fertilizers, cement additives, and construction aggregates.
