The carbon leaves the converter as a gas, carbon monoxide, which can, after cleaning, be collected for re-use as a fuel. During the ''blow'', lime is added as a flux to help carry off the other oxidized impurities as a floating layer of slag.The quantities of scrap, hot metal and lime and other fluxes are calculated to ensure the correct steel temperature and composition.
