    Optimum design and layout of the cooling apparatus for long compaignship blast furnace

    Generally, the cooler life can determine the blast furnace life. The slag-metal skull frozen on the cooler can separate the cooler from the hot gas flow in blast furnace. The key problem is how to freeze liquid slag-metal on the cooler, and the main measure is to decrease the hot surface temperature of the cooler. The computational technology of heat transfer was practically used for long campaign blast furnace design. The optimum design of the cast iron stave, copper stave, plate-stave combined system and flangestave was given by the computing results. According to the results, the optimum arrangement of different coolers (cast iron or copper stave, flange stave and plate-stave combined system) on different height of blast furnace wall can be found through all these temperature fields.
