How we make steel British Steel

Using a watercooled lance, high purity oxygen is blown at twice the speed of sound onto the surface of the liquid iron at very high pressure. Lime is added to the process, which forms a slag and removes the unwanted elements from the liquid steel. When the oxygen blowing process is complete, the steel is poured or tapped into ladles ...

Steel production: from iron ore to functional industrial products. Vepica

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The orebased process uses a blast furnace or smelter and the scrapbased process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.

Making steel | ArcelorMittal

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. Both processes are being continually improved ...

Raw materials Sinter plant | ArcelorMittal

The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an opengrained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.

Steel manufacture

Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an ironrich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.
