摘要
高炉炉缸和炉底的寿命是影响高炉长寿的关键因素之一。实现高炉炉缸、炉底与高炉寿命同步的措施之一就是在高炉炉缸和炉底冻结一层渣铁壳。要想冻结渣铁壳,在高炉设计时应将1150℃等温线推离炉缸和炉底热面,这就需要计算高炉炉缸和炉底的温度场。为此讨论了目前应用于高炉炉缸和炉底温度场的一些数学模型,并在此基础上开发了通用的炉缸、炉底温度场计算软件。
The hearth and hearth bottom life of blast furnace is one of the key factors affecting blast furnace life. In order to make the hearth and hearth bottom have the same life-span as that of blast furnace, one of effective measures is to form a layer of slag-metal skull on the hearth and hearth bottom. In order to form a layer of slag-metal skull, the 1 150 ℃ isothermal line should be moved off the hot surface of the hearth and hearth bottom during designing blast furnace. Therefore, it is necessary to compute the temperature field of the hearth and hearth bottom. So some usual mathematical models of the temperature field for the hearth and hearth bottom of blast furnace were discussed. The calculating software of the temperature field of the hearth and hearth bottom was developed.
