How to increase the ration of iron and heat recovery from the smelting steel slag is an important issue in metallurgy. So a study of extracting iron from converter slag was done by smelting reduction method. Here we studied the effect of CaO/SiO2 on the recovery during smelting reduction. Results showed that the CaO/SiO2 directly regulated the reduction reaction of Fe2+ / Fe3+, the viscosity of slag...
In order to utilize the both slag and heat energy of the smelting steel slag, the experiments of extracting iron from steel slag were conducted by smelting reduction method, and investigating the effect of temperature and holding time on iron recovery ration. Results show key reduction reaction is (FeO) +C=[Fe]+CO. And maximum reduction ration reaches on 94.82% under optimum temperature 1550°C and...
As one of the major coal consumption and energy-hungry industries, steel industry has emitted large quantities of carbon dioxide to the atmosphere. In order to save energy and reduce carbon emission in steel industry??a researching on the CO2 emission of a typical steel factory which is one of Chinese largest steel production plant has been carried out, the CO2 reduction potentials and its reduction...
