介绍了由煤气发生炉、煤气加热炉和还原竖炉组成的Ｃｏｒｅｘ竖炉还原热模拟装置，用木炭或用原煤加少量木炭为原料，Ｏ２和ＣＯ２为气化剂，产生还原煤气，将铁矿石还原成金属化率达９０％以上的海绵铁的过程。描述了还原过程中坚炉内的温度分布、熔剂分解和不同炉料结构时的海绵铁粒度组成和金属化率等试验情况，讨论了还原煤气的成分、温度、流量、还原时间以及炉料结构等对海绵铁金属化率的影响。
The Corex shaft furnace heat recovery simulation system consisting of a gas furnace, a gas furnace and a reduction shaft furnace is introduced. Charcoal or raw coal plus a small amount of charcoal is used as a raw material, and O2 and CO2 are used as gasification agents to generate reducing gas. Iron ore Stone reduction to metalization rate of 90% or more sponge iron process. Describes the experimental results of the temperature distribution in the furnace during the reduction process, the flux decomposition and the composition of the sponge iron and the metallization ratio in different charge structures. The effects of composition, temperature, flow rate, reduction time, Effect of iron metallization rate.
