Making Steel Coking plant Coke's role in steelmaking is to provide the heat needed to melt the ore, whose natural state is iron oxide, the rust you see on iron after it has been exposed to the atmosphere. Coke also 'steals' the oxygen from the iron ore, so that it can become iron.

Amongst other leaders that worked on this subject, Heinrich Koppers introduced the coke oven process into the US industry in 1907. Establishing Heinric Koppers AG in 1904, he created the socalled 'half direct' process for recovery tar and ammonia from coke oven gas. By 1923, 90 % of all coke oven plants in the Ruhr district used this process.

1. OBJECTIVE: The main function of Coke Ovens is to convert coal into coke which is used as a fuel and reducing agent in the Blast Furnace. Its secondary function is to recover Volatile Matter and CO (Coke Oven) gas from coal and extract chemicals known as Coal Chemicals. CO gas produced is used for heating purposes in the plant.

Elemental carbon in iron and steel enterprises primarily enters in the form of coal and raw materials containing carbon. In the coking process, washed coal is indirectly heated, and dry distilled through the combustion of gaseous fuels (natural gas, coke oven gas, etc.) in the combustion chamber and is converted into secondary energy such as coke and coke oven gas (COG).
