A mathematical model of heat loss of high temperature smoke vented from rotary anode furnace in copper refining based on warm-up burning air was established based on principle of energy balance.
Steel and iron manufacturers also extensively use oxygen or oxygen-enriched air to affect chemical refining and heating associated with carbon removal and other oxidation reactions.
