Taking a closed reduction smelting blast furnace in Congo(Kinshasa)as an example,combined with the characteristics of the blast furnace hearth and the erosion characteristics of refractory materials inspected during multiple major repairs,this paper analyzes the main influencing factors of refractory material erosion,and combines production practice to explain measures to extend the service life of the blast furnace hearth.Research has found that the erosion of refractory materials is mainly affected by factors such as slag chemical erosion,copper matte infiltration,and melt erosion.After the corresponding measures are implemented,the service life of the blast furnace hearth can be extended by at least 5 months.
