Influencing factors of burden temperature change above thermal reserve zone of blast furnace
Combined with the furnace profile,the raw material conditions and the operating conditions,the calculation formula of temperature changes for the burden and the gas above the thermal reserve zone was derived.The influences of various factors on the burden temperature and the gas temperature were studied quantitatively.The results showed that the shaft furnace profile had little effect on the heating process of the burden.The height above the thermal reserve zone was suggested to design more than 12 m.The burden grade and the heat capacity had a greater impact on the burden heating process.The energy efficiency of the gas would be reduced with increase of the initial temperature of the burden.
