    Abstract: A physical model of melting furnace for producing molten iron is established. Paraffin particles are used to simulate ores. Corn particles are used to simulate coke. The gas phase temperature in the furnace was measured with a temperature sensor. The temperature gradient analysis was used to study the effect of cohesive zone on the material layer. The study found that the higher the melting point of the experimental materials, the higher the cohesive zone temperature, resulting in the higher the overall temperature of the material layer, which is conducive to improving the utilization rate of gas. At the same time, the heat transfer process of cohesive zone will become more intense. The results presented in this paper will have certain guiding significance for the research of cohesive zone and solid layer of blast furnace.

    Abstract: In this paper, the tailings produced by non-ferrous metallurgy were magnetically separated to obtain magnetic separation tailings. The sintering performance of magnetic separation tailings was studied by sintering cup experiment platform. In the research process, the differences in sintering process of different magnetic separation tailings were compared, including vertical sintering speed, sintering coefficient, drum strength, finished product rate, end point temperature and other sintering indexes. At the same time, the obtained sinter was subjected to chemical analysis to obtain its specific components. The influence of magnetic separation tailings with different contents on sintering was obtained by ore blending. The experimental results showed that the copper tailings are not sintered and the yield is only 0%. Tin tailings are not sintered and the yield is only 22.30%. The aluminum tailings can be s intered into lumps with a yield of only 57.10%. As the proportion of magnetic separation tailings increases, the vertical sintering speed decreases, the sintering utilization coefficient decreases, the sinter drum index decreases, the yield decreases, the sinter grade decreases, and the SiO 2 , S and P contents increase. In actual production, the proportion of magnetic separation tailings should be controlled below 10%.
