摘要
在高炉冷却器及炉缸、炉底热面凝结一层渣铁壳有利于防止炉衬侵蚀,延长高炉寿命。为了达到这一目的,需要设计无过热的铸铁冷却壁、铜冷却壁和板 壁结合冷却器以及无过热的炉缸和炉底。为此建立了高炉炉身下部冷却器及炉缸、炉底温度场的数学模型,应用C++语言在VC++集成环境下开发了高炉炉身下部冷却器及炉缸、炉底温度场计算软件。计算结果表明,通过优化炉身下部冷却器及炉缸、炉底的设计参数,能够确保在冷却器热面及炉缸、炉底热面凝结一层渣铁壳。目前,国内一些大型高炉的设计中已采用该软件。
A model for calculating the temperature distribution of the stave and the hearth bottom and a mathematical model of temperature distribution of lower shaft cooler and hearth bottom of blast furnace were built. The computational software of the temperature field was developed by using C++ language in VC++ integrated environment. The calculation results show that the formation of the protection shell can be achieved by optimizing the parameters for designing the stave and the hearth bottom. The software has been used to design blast furnace of some large companies in China.
