steel | Composition, Properties, Types, Grades, & Facts ...

Steel, alloy of iron and carbon in which the carbon content ranges up to 2 percent (with a higher carbon content, the material is defined as cast iron). By far the most widely used material for building the world's infrastructure and industries, it is used to fabricate everything from sewing needles to oil tankers.

Iron and Steel Slag Statistics and Information

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.

Finally, you roll or otherwise shape the steel into the finished product. Making steel from iron. Photo: Making steel from iron with a Bessemer converter.

SLAG ANALYSIS SOLUTIONS - Bruker

Optimum slag viscosity • The most important factor affecting slag viscosity is the presence of suspended second phase particles (MW & C2S) in the slag FeO content of the slag • Sufficient FeO in the slag is required to react with carbon and generate CO gas bubbles • Too much FeO is equated with iron loss MgO content of the slag

IRON SLAGS ON ARCHAEOLOGICAL SITES: AN INTRODUCTION Lynne Keys HISTORICAL METALLURGY SOCIETY WHAT IS IRON SLAG? There are many different types of iron slag. Some were produced by smelting, others by smithing; some are large, some so tiny they are invisible to the naked eye when in the soil.

10 Best Uses of Iron In Everyday Life and the Human Body

Also the magnetic properties iron has makes it useful for making electric mortars and fans which run on electricity. Fencing: Fencing or boundary wire of farms and grounds are made of iron. Compared to other metals, iron is cheaper and also more durable.

Measurement of metallic iron in steel making slags ...

The steel slag is subjected to crushing/magnetic separation to generate different sizes of slag products with varying metallic values. Based on size and metallic content, these products are recycled in sinter base mix, iron making units and as scrap in steel making process.

Recovery of high grade iron compounds from LD slag by ...

Jan 10, 2014· Less recovery can be observed for particles < 1 mm. However, the iron content in non-magnetic fraction is the same as feed materials. From these results, it can be noted that the dry magnetic separation may be applied on the coarse fraction of LD slag to recover only iron scraps.

Enhancement of Iron Recovery from Steelmaking Slag Fines ...

Jul 28, 2016· Steelmaking slags are usually processed for iron recovery by dry magnetic separation. 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 ...

How iron is made - material, manufacture, making, history ...

Historically, iron was produced by the hot-blast method, or later, the anthracite furnace. Either way, the fundamental activity in iron making involved a worker stirring small batches of pig iron and cinder until the iron separated from the slag.
