宝钢3BF高炉大修无料钟炉顶装料设备优化设计

Optimization Design of Charging Equipment for Bell-Less Top in Baosteel 3BF Rebuilding

宝钢3BF高炉大修重建工程中,炉顶装料设备采用旋转受料罐+吊挂式称量料罐的串罐式无料钟炉顶形式,并优化了各部件的结构。其中旋转受料罐采用大齿圈+支撑轮+导向轮取代原设计的带齿回转轴承,上料闸采用单侧油缸驱动取代原设计的双侧油缸驱动,称量压头设计安装在吊杆上,过渡短管代替眼镜阀。

Baosteel 3BF （ blast furnace ） rebuilding project adopt centrally fed bell less top by rotary re-ceiving hopper ＋hanging weighing hopper and optimize the structure of each component .The rotary receiving hop-per use the structure of gear ring ＋support wheel and guide wheel instead of tooth type bearing .Charger gate adopt unilateral cylinder instead of bilateral cylinder driving , load cells design mounted on the hanging rod , the transition pipe instead of glasses valve .
