Abstract
In order to explore the impact of the chemical ingredients of ore powder on basic properties and guide production to optimize ore blending. This article takes common mineral powder raw materials produced by a steel company as the research object, and conducts experimental tests on the features of high-temperature sintering of raw materials. The result shows that the chemical composition of ore powder itself will have a great impact on its high-temperature basic properties. The high mass fraction of SiO2 will improve the assimilation performance and flow performance of ore powder. The bonding phase strength first rises and subsequently falls as the SiO2 mass fraction increases. Iron ore powder containing a higher MgO mass fraction will deteriorate the basic performance. Based on the research results, an ore blending optimization experiment was conducted to adjust the raw material ratio, increase the ratio of E mineral powder with superior high-temperature performance, and reduce the content of F mineral powder.
