Embodiment
[0022] This embodiment discloses a method for improving the performance of the slag, which not only solves the problem of feeding raw material into the furnace, but also effectively prevents the thickening of the slag, improves the performance of the slag, reduces abnormal furnace conditions, and reduces iron loss.
[0023] Specifically, the method includes the following steps: Step 1, adding fluorspar powder to the sintering ingredients for adding the sintered ore to the blast furnace; it is beneficial to the stability of the furnace condition. Preferably, in the present embodiment, the fluorite powder is selected from CaF 2 Fluorite powder with a mass content of 84.5%. Furthermore, the added fluorite powder is sintered clinker, which is beneficial to reduce the combustion ratio of the blast furnace.
[0024] Step 2, adjusting the proportion of the fluorite powder in real time according to the change of the viscosity of the slag.
[0025] The sintering ingredients and sinte...
