Therefore, coke (C) is a better reducing agent than CO at 983K or above temperature. However below this temperature (e.g. at 673K), CO is more effective reducing agent than C. 3. Yes, it is possible to reduce Fe 2 O 3 by coke at a temperature around 1200 K. In the Ellingham diagram, carbon line cuts across the lines of many metal oxides and

US3771999A - Slag-making methods and materials - Google

A lime product is intimately coined with a halogen compound and preferably one or more other fluxes to form a reactive flux addition which is used in steel making. The flux addition is obtained by burning a CaCO3 bearing material in the presence of auxiliary fluxes or by briquetting a mixture of lime and auxiliary fluxes, including a halogen compound.
