How is steel made?
For easier understanding, steel is made through 3 different stages which are ironmaking, steelmaking and rolling (continuous casting processes). 1) Ironmaking: a process of smelting iron ores into hot metal. Iron ore and coal are gathered from all around the world and unloaded onto the raw materials dock.
Is coal the only way to make steel?
The good news is that coal is not our only option. You need three things to make steel: a whole lot of heat, some way to remove oxygen to turn iron ore into iron and a little bit of carbon to turn the iron into steel.
How much steel is produced from 1 ton of coal?
Around 0.6 tonnes (600 kg) of coke produces 1 tonne (1000 kg) of steel, which means that around 770 kg of coal are used to produce 1 tonne of steel through this production route. Basic Oxygen Furnaces currently produce about 70% of the world鈥檚 steel. A further 29% of steel is produced in Electric Arc Furnaces. Electric Arc Furnaces
What are the two main raw materials for steelmaking?
We mine iron ore and metallurgical coal, the two main raw materials for steelmaking, at open-pit and underground mines around the world. There are three main raw materials needed to make steel. Iron ore, coal and scrap steel.
