process of making iron and steel

iron and steel chemguide

Steel-making: the basic oxygen process. Impurities in the iron from the Blast Furnace include carbon, sulphur, phosphorus and silicon. These have to be removed. Removal of sulphur. Sulphur has to be removed first in a separate process. Magnesium powder is blown through the molten iron and the sulphur reacts with it to form magnesium sulphide. This forms a slag on top of the iron and can be

Steps in the Modern Steelmaking Process

21/08/2020· Ironmaking, the first step in making steel, involves the raw inputs of iron ore, coke, and lime being melted in a blast furnace. The resulting molten iron—also referred to as hot metal—still contains 4-4.5% carbon and other impurities that make it brittle. Primary steelmaking has two methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. The BOS

Ironmaking Process an overview ScienceDirect Topics

04/04/2012· In 1988, Iron Age examined the prospects of iron- and steelmaking, and the article quoted Egil Aukrust, the technical director of LTV Steel, who saw an early end of the era of oxygen steelmaking as a new process in which BOF and EAF get together for an in-bath smelting reduction (McManus, 1988b). And the same article cited the AISI estimate that it would take 10 years before Klöckner-CRA

The Process of Making and Refining Steel from Raw Iron

27/04/2017· Primary Steel-making- This process chiefly utilizes new iron samples as the feedstock from a blast furnace. Secondary Steel-making- The primary raw material in this procedure is scrap steel

Steelmaking Process an overview ScienceDirect Topics

Since scrap metal is used instead of molten iron, no coke making or iron making operations are associated with steel production using an EAF. This technology results in the production of metal dusts, slag, and gaseous products. Particulate matter and gases evolve together during the steelmaking process and are conveyed into a gas cleaning system. Emissions are cleaned using a wet or dry

How we make steel British Steel

Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it’s poured from the torpedoes into refractory-lined charging

Infographic: the Iron and Steel Manufacturing Process

Steel is made primarily in a two-step process. In the primary steelmaking step, liquid iron is converted into steel by the basic oxygen furnace (BOF) process, or by melting scrap steel or direct reduced iron (DRI) in an electric arc furnace. Secondary steelmaking is a refining process

Steel Manufacturing Process Association for Iron & Steel

The process starts in the center of the wheel with the three main ingredients of iron in the form of iron ore, coke and lime, which are fed into a blast furnace to produce molten iron. The molten iron is mixed with recycled steel scrap and further processed in a basic oxygen furnace to make steel. The electric arc furnace melts recycled steel scrap. The molten steel is formulated to precise

Iron and Steel Industry: Process, Location and Early

The basic process involved into the iron and steel production is the refinement of iron ore. Usually, coal and limestone is used for this refinement. The heat harnessed from coal is required to run blast furnaces. Limestone is used as fluxing material, which helps to remove impurities from iron ore. The product thus produced is widely known as pig iron. The further processing of pig iron

Bessemer process Wikipedia

The process also decreased the labor requirements for steel-making. Before it was introduced, steel was far too expensive to make bridges or the framework for buildings and thus wrought iron had been used throughout the Industrial Revolution. After the introduction of the Bessemer process, steel and wrought iron became similarly priced, and
