Abstract：The development of fluxed pellets is one of the current directions and hot spots in the development of ironmaking process technology. The basicity of the pellets is different, and its physical and chemical properties and metallurgical properties are also different. The effects of basicity on the compressive strength of the Baiyun Obo iron concentrate briquetting were investigated by analyzing the change regularity of the ore-phase structure of the pellets with different basicity. The results showed that with the increase of basicity, the compressive strength of the briquetting increased first and then decreased. The increase of the amount of liquid phase made the porosity of the briquetting decrease and the strength of it increase. However, too much liquid phase will destroy the overall structure of hematite. The strength of the slag phase was lower than that of hematite, and the strength of the briquetting was gradually reduced gradually.
