Abstract
In order to reduce the sintering allocation scheme and lower the cost of allocation, two semi-lignite ores with similar properties and large price differences were selected for blending to achieve the purpose of complementary advantages. The sintered ore specimens were studied by using FactSage7.1, an infrared sintering furnace, and regression analysis. The results show that OA and OB iron ore powders and their mixed iron ore powders have a good linear fitting effect with an inverse relationship between bond phase strength and SiO2 content; the bond phase strength has a positive relationship with liquid phase fluidity index; when mixing OA and OB iron ore powders in the ratio of 4:6, they have better sintering base characteristics and can be used as a new iron ore powder.
