Physical Simulation Study on Influence of Iron Ore Melting Point on Cohesive Zone and Material Layer

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.
