Modern steel making process uses a blast furnace for manufacturing steel. It can be divided into two categories: primary and secondary. Primary steel making includes “converting liquid iron from a blast furnace and steel scrap into steel via basic oxygen steel making or melting scrap steel and/or direct reduced iron (DRI) in an electric arc furnace”.

EXTRACTION OF IRON

The air blown into the bottom of the furnace is heated using the hot waste gases from the top. Heat energy is valuable, and it is important not to waste any. The coke (essentially impure carbon) burns in the blast of hot air to form carbon dioxide - a strongly exothermic reaction. This reaction is the main source of heat in the furnace.

Blast furnaces are used for extracting fairly reactive metals (e.g. iron, zinc) by reducing the metal oxide with carbon. Iron extraction from its oxides Iron is extracted from haematite and magnetite (different oxides of iron). This happens in a blast furnace. A blast furnace is roughly 50m high, and lined with heat–resistant bricks. The haematite (the ‘charge’) is loaded into the blast ...

2020-6-7 · 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 ...

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.

2017-9-3 · Brownian motion describes the erratic and irregular motion of particles, such as pollen grains in water. How it occurs Brownian motion happens when particles that are free to move around and collide with each other, making them both bounce off in different directions. Many of these collisions occur to create the random paths that the particles take. It occurs when gas particles spread out, a ...
