A reducing agent (also called a reductant or reducer) is an element or compound that loses (or "donates") an electron to another chemical species in a redox chemical reaction.
Since thereducing agent is losing electrons, it is said to have been oxidized.
Coke is a good reducing agent, especially at higher temperatures, because it is a non-metal and it combines with oxygen and forms its gaseous non-metallic oxides.
It helps in oxidation.

Answer:
Here you go
Explanation:
A reducing agent is a chemical that gives away electrons to another chemical compound, the oxidizing agent. For example, zinc is a reducing agent. When it reacts with an oxidizing agent, it gives up two electrons, changing its oxidation state from 0 to +2. All chemical elements have an oxidation state of 0.
The combustion of coke, which is maintained by the supply of preheated air (blast), provides CO to reduce iron oxides to iron and provides energy in form of heat to melt the iron and impurities.
