Host Factor: Genetic PolymorphismSuccess and efficiency of a process are depending on the thermodynamic calculation of the reactions. How much reducing gas (CO) required to reduce iron oxides at different stages and temperatures that should be known before the actual process, i.e. how much reductant is required for the process.

Host Factor: Genetic PolymorphismBessemer proposed a production method of steelmaking within a very short time (15–20 min) by blowing air through molten pig iron without using fuel. Siemens brothers, Germany, developed temperature of the furnace around 1600 ℃ for the first time, on the principle of regeneration of heat from exhaust gases.
