Based on the pellet bulk compositions in shougang, the liquid proportion of pellets under different firing temperature with w（SiO₂）from 2.4% to 8.0% and w（CaO）from 1% to 5% is calculated using Fact Sage 7.1. The results show that when the basicity of pellets is about 1.25, the pellets formation temperature of liquid phase is higher, but with the increase of firing temperature, the liquid proportion also increases rapidly. The pellet firing temperature is in the high side, decreasing the firing temperature（about 30 ℃）can still ensure the liquid production of 5%. When the pellet w（CaO）is 3.4%, suitable w（CaO）is 0.5% when fired at 1 280 ℃, and w（CaO）can be added to 4.6% fired at 1 250 ℃. The study on pellet liquid proportion is expected to provide reference for the adjustment of pellet basicity and the control of firing temperature, as well as for the optimization of burden structure.
