Optimized integration of super-large top-fired stove technology; research and development of combustion air two high-temperature preheating technology and top-fired stove high efficiency ceramic burner. According to the characteristics of top-fired hot blast stove, a reasonable structure of vault and ceramic burner was designed. By using highly efficient checker bricks, the thermal parameters and structure of regenerator were optimized, and the reasonable heat storage area of ​​hot stove was determined. Optimization of hot-blast furnace lining design; used to effectively prevent the hot-blast furnace shell stress corrosion between the technical measures. According to the regenerator heat transfer calculation, a reasonable allocation of hot-blast furnace refractories, improved refractory technical performance. Optimize the structural design of hot-blast piping system refractory material to rationalize hot-blast piping system and meet the requirements of high temperature of 1 300 ℃. Blast furnace put into operation after the hot air temperature reached the design level, the average monthly temperature of 1 300 ℃.
