Steel making

Since steel making is a dynamic process the concentration of carbon and oxygen in the bulk metal phase is not in equilibrium with the prevailing CO- pressure in the bubbles At the gas bubble–metal interface the reaction is close to equilibrium The experimentally observed excess oxygen and carbon in the bulk metal phase is thus helpful in
