The haematite is widely used for the production of pig iron. Since pyrite contains only 30 to 40% iron, therefore it is not used for manufacturing pig iron. The pig iron is obtained from the iron ores in the following steps: 1. Concentration. It is the process of removing the impurities like clay, sand etc. from the iron ore by washing with ...

The manufacture of iron artifacts then required a shaping operation, which involved heating blooms in a fire and hammering the red-hot metal to produce the desired objects. Iron made in this way is known as wrought iron. Sometimes too much charcoal seems to have been used, and iron-carbon alloys, which have lower melting points and can be …

Check out this infographic for an overview of the products that make each stage of the iron and steel manufacturing process possible, …

Billets are semi finished product. We manufacture square billets of size 100*100 sq.mm. We use Induction furnaces and continuous casting machine for billets manufacturing. The process of manufacturing Billets is a two stage process. The first stage consists of feeding M.S. Melting scrap, Sponge Iron, Pig Iron and other alloys in the induction ...

Before iron ore can be used, oxygen must be removed from it. Known as 'reducing', this can be done either in the blast furnace, where hot air is injected into a continuous feed of coke, sinter and lime, or by the direct reduced iron (DRI) process. The result from both is liquid iron, which is then transported to the basic oxygen furnace. The blast furnace …

For general information about merchant pig iron, please visit the pig iron page. Modern blast furnaces produce more than 10,000 tonnes per day. Blast Furnace Process. The blast furnace is a counter-current gas/solids reactor in which the descending column of burden materials [coke, iron ore and fluxes/additives] reacts with the ascending hot gases.

Steel Manufacturing Process. To produce steel first the iron ore is heated and melted in a furnace. The impurities are then removed from the molten iron. Carbon and other required alloying elements are added to make …

Iron ore is used mostly in pellet and/or lumpy form. Oxygen (O2) is removed from the iron ore by chemical reactions based on H2 and CO for the production of highly metalized DRI. In the direct reduction process, the solid metallic iron (Fe) is obtained directly from solid iron ore without subjecting the ore or the metal to fusion. Direct ...

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. A third group …
