body burden
2.Abstract: The furnace body erosion of 2# blast furnace of PZH Steel at the end of second compaign wassystematically investigated.The causes for furnace body erosion were analyzed.The features of furnace body erosion were clarified under conditions of intensification of smelting process.The mechanism of lining protection was further revealed with TiO2 bearing burden,the technical measures which make the blast furnace high efficiency and long compaign were put forward.
