摘    要：在首秦公司引进、消化俄罗斯卡卢金顶燃式热风炉技术基础上,分析其技术优点和存在的不足,自行设计热风炉炉型、燃烧器结构多种方案,采用仿真、试验等手段研究了煤气、空气旋角、位置和布置方式变化的基本规律,并优选了一种可行方案,在迁钢2号高炉预热炉上进行应用试验。仿真和冷态试验结果表明,新开发的热风炉具有结构紧凑,工艺设计简单,炉顶、炉墙温度较低,燃烧完全等优点。投产应用表明,该热风炉运行良好,风温达到预期目标,满足了高炉炼铁生产需要。该技术的开发和应用,可以为国内大型高风温热风炉设计提供参考。

Abstract: Based on imported Russian Kalugin top combustion BF stove in Shouqin,analyzing the advantages and disadvantages of it,different structures of BF stove were designed.The angle of gas and air jets,reasonable structure of BF stove were studied then through simulation and experiment,a suitable design was accepted and tested.Simulation and test indicates that new developed BF stove is of compact structure,simple in design,has lower temperature at top and wall.The operation indicated that the BF stove runs well,blast temperature satisfies iron-making.Such BF stove technology could be used to design large high temperature stove.
