Blast furnace - Wikipedia
Coke iron was initially only used for foundry work, making pots and other cast iron goods. Foundry work was a minor branch of the industry, but Darbys son built a new furnace at nearby Horsehay, and began to supply the owners of finery forges with coke pig iron for the production of bar iron.
The purpose of adding coke to the iron ore in a …
COKE acts as a reducing agent. It combines with oxygen to form CO which in turn reacts with iron ore to give metallic Iron. Carbon present in coke also produces heat in all oxidation reactions which melts down the metallic iron. LIMESTONE (CaCO3) breaks down to CaO upon heating which reacts with SiO2, the main impurity, to flux it out of the ...

How is Steel Produced? | World Coal Association
Iron ore is produced in around 30 countries – in 2017, the largest producers were Australia, Brazil and China. Around 98% of iron ore is used in steel-making. During the iron-making process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
What is the role of coke in the extraction of iron - …
It is carbon (in the form of coke) that is added to blast furnaces to reduce iron oxide and recover the iron. This is the usual explanation, though most believe that it is the action of carbon monoxide that is involved.
Coke in the iron and steel industry - ScienceDirect
Foundry coke is produced in coke ovens and is used at foundries to melt iron and various copper, lead, tin, and zinc alloys in cupola furnaces. • Domestic coke, or semicoke, is used as a fuel. A low-ash, easily ignited coke of high calorific value with a very low sulfur content is required.
The Extraction of Iron - Chemistry LibreTexts
Iron ore is not pure iron oxide - it also contains an assortment of rocky material that would not melt at the temperature of the furnace, and would eventually clog it up. The limestone is added to convert this into slag which melts and runs to the bottom. The heat of the …
The Blast Furnace
At the same time the iron oxides are going through these purifying reactions, they are also beginning to soften then melt and finally trickle as liquid iron through the coke to the bottom of the furnace. The coke descends to the bottom of the furnace to the level where the preheated air or …
