High Phosphorus Iron Ore

A series of smelting reduction experiments has been carried out with high-phosphorus iron ore of the different bases and heating rates by thermogravimetric analyzer. The derivative thermo gravimetric (DTG) data have been obtained from the experiments. After analyzing its phase space reconstruction, it is found that DTG phase portrait contains with a clear double “∞” attractor characteristic by one-order delay. The statistical properties of the attractor inside and outside the double “∞” structures are characterized with interface chemical reaction control and diffusion control stage in dynamic smelting process, respectively; the results are deserved to be a reference value on understanding of the mechanism and optimization and control of the process in smelting reduction of high-phosphorus iron ore.

High Phosphorus Iron Ore

In order to promote the rational utilization of high-phosphorus iron ore in western Hubei of China, the effect of process parameters on desilication rate of the high-phosphorus hot metal was investigated. The results show that the desilication rate increases slightly with indistinctive effect with the increasing of desilication agent addition. The oxygen efficiency is over 50% when desilication agent addition is about 30kg/t. Desilication rate is higher when the stirring gas flow is about 0.4l/min. Strengthening stirring of bath at the beginning period can improve kinetics condition of desilication reaction.
