2 Materials Used to make Steel 2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe)
The first metallurgical step involved in this process is to reduce iron ore to metallic iron in a blast furnace, using coke as both a fuel and reducing agent. The produced metallic iron contains a relatively high proportion of carbon (4%) and it is passed to the steelmaking process in
Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800 F in the absence of oxygen
Steel Manufacturing process Steel making is the process of making steel from iron ore and/or scrap. In steel making, impurities such as nitrogen, silicon excess carbon etc are removed from the sourced iron and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and
Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make
Oct 23, 2017 Oct 23, 2017 The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash)
Nov 01, 2017 Iron ore, coking coal, and limestone are added into the top of the blast furnace while heated air is blown into the bottom of the furnace to drive the combustion process. The combustion of iron
The advantage of steel over iron is greatly improved strength. The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface
Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable. Iron ore can be found all over the world, but its iron
Process of making steel from iron ore with flow charts Products. As a leading global manufacturer of crushing, grinding and mining equipments, we offer advanced, reasonable solutions for any size-reduction requirements including, Process of making steel from iron ore with flow charts, quarry, aggregate, and
Jun 22, 2018 Jun 22, 2018 To make steel, Iron ore and other iron bearing materials, coke, and limestone are charged into the blast furnace from the top and work their way down, becoming hotter as they sink in the body of the furnace. At the bottom of the furnace, temperatures rise to well over 3000 F. Molten slag floats on a pool of molten steel that is four or five
Feb 21, 2016 Feb 21, 2016 Steel making process 1. STEEL MAKING PROCESS 2. Steelmaking is the process for producing steel from iron ore and scrap. What it is the Steel making process? 3. First stage Preparing the mineral of iron It starts in the mine or quarry, where it s obtained. In nature is a rock whith iron, oxide, dirt and other impurities. 4
Aug 28, 2019 Steelmaking process involves the production of steel from iron ore and scrap. In this process, various impurities such as silicon, sulfur, nitrogen, phosphorus, and excess carbon are removed from the sourced iron. And, to produce different grades of steel, alloying elements such as nickel, manganese, chromium, and vanadium are added
Jan 14, 2020 Jan 14, 2020 By the time coal fills in the kiln, we stop adding ore. Check and remove the furnace to get iron from the furnace. At this point we see the amount of pure iron will be melted and clumped together into a lump, clinging around it is the iron residue. Use a wooden hammer to break each bit to remove iron
Steel Manufacturing process Steel making is the process of making steel from iron ore and/or scrap. In steel making, impurities such as nitrogen, silicon excess carbon etc are removed from the sourced iron and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel.

Oct 23, 2017 The pig iron itself does not have much use but it finds a great number of applications when converted into steel alloys in the steel industry. The process of manufacturing pig iron is a bit complicated. The following steps explain the same as simply as possible. Raw Materials-The raw materials used in the blast furnace to produce high-quality pig iron are iron-ore, coke, limestone, and sinter. Now, these iron ores are
