Iron processing Iron making Britannica

Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.

Steel Production American Iron and Steel Institute

The first blast furnaces appeared in the 14th century and produced one ton per day. Even though equipment is improved and higher production rates can be achieved, the processes inside the blast furnace remain the same. The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process.

Steelmaking Process an overview ScienceDirect Topics

During the steelmaking process, fluxes that consist of lime (CaO) or dolomitic lime, with iron and scraps, are charged to the furnace.There is a certain amount of free lime (f-CaO) in steel slag. Free lime, with a specific gravity of 3.34, can react with water to produce Ca(OH) 2, with a specific gravity of 2.23, which results in volume increase (Fig. 9.1).

Glossary of Steel Industry Terms American Iron and Steel

The basic fuel consumed in blast furnaces in the smelting of iron. Coke is a processed form of coal. About 1,000 pounds of coke are needed to process a ton of pig iron, an amount which represents more than 50% of an integrated steel mill’s total energy use. Why? Metallurgical coal burns sporadically and reduces into a sticky mass.

Basic oxygen steelmaking Wikipedia

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz–Donawitz-steelmaking or the oxygen converter process is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel.The process is known as basic because fluxes of burnt lime or

Energy Efficiency and Iron and Steel Production IspatGuru

Sep 09, 2014 The energy intensity of this route ranges from 9.1 to 12.5 GJ per ton of crude steel where the input is only the steel scrap. Another way to produce crude steel is by directly reducing iron ore to produce direct reduced iron (DRI). The average energy intensity is typically between 28.3 and 30.9 GJ per ton of crude steel.

Direct reduced iron Wikipedia

Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
