Coke is used as a fuel and a reducing agent in melting iron ore. It is produced by baking coal until it becomes carbon by burning off impurities without burning up the coal itself. When coke is consumed it generates intense heat but little smoke, making it ideal for smelting iron and steel. Prior to the 1880's, steel was produced using charcoal.

It was once used to make decorative gates and railings, but these days mild steel is normally used instead. Mild steel: Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used ...

By Noah Beecher Kelk. Metallurgical coal, also called metcoal or coking coal, is a type of coal that is used in the production of steel. It is of a higher purity than thermal coal which is used in energy generation. To make steel, metcoal is heated at around 1100 degrees C to remove water and other chemicals.

Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it's poured from the torpedoes into refractory-lined charging ...
