Adiabatic Carbon Rate of Alternative Ironmaking Processes to Produce Hot Metal

  From economic viability and sustainable development of view,the future alternative ironmaking processes,in general,may be classified into two representative routs,“Pre-reduction---Smelting reduction process and “Direct reduction---Melting process.In the present work,aimed for hot metal production,the carbon rate (in kg/THM) is considered as the yardstick for the measurement of the “goodness of these two processes,because it reflects the consumption of coal and energy,and the amount of carbon dioxide eventually to be emitted to atmosphere.By the thermodynamic calculation,under the idealized conditions,the total adiabatic carbon rate along “Direct reduction---Melting process is approximately 145kg/tHM lower than that along “Pre-reduction---Smelting reduction process.Therefore,direct reduction would likely lead to an alternative process with much lower carbon rate,and it should be reasonable and successfully developed.
