摘　　要：包钢新建成一条国内最大的624m^2大型带式焙烧机球团生产线，年产氧化球团500万吨。在设计过程中，对风流系统进行了优化设计，自主设计开发了多项新型设备，如大型球团干燥窑、往复式布料机、回转支撑造球机和稳流给料斗等，并集成应用了立式强力混合机和高压辊磨机等多项国内外大型装备。设计过程充分考虑节能环保因素，生产能耗低，粉尘排放、噪音污染均维持较低水平，除尘灰二次利用，无固体废弃物外排。自2015年底投产以来，设备运行稳定，生产指标良好，球团的TFe达到65％以上，抗压强度≥3100N，工序能耗17.05kgce／t，达到国际先进水平，实现了良好的经济社会效益。The most large-scale travelling grate machine pelletizing plant with working area of 624 m^2 and annual output 5.0 million was built up at Baogang. The airflow system was designed optimally. Multiple novel equipments were designed and developed independently like large drying kiln, reciprocal feeder, rotary supporting pelletizing disc and steady flow feed hopper, etc. What＇s more, some large-scale equipments, such as vertical intensive mixer and high-pressure grinding roller from home and abroad were integrated. Energy conservation and environment protection was fully considered during the design process, which brought about lower energy consumption, dust emission and noise pollution. The precipitator dust was totally reused and few solid waste was discharged. Since starting in December 2015, the equipment has been running smoothly with favourable production index. The iron grade of pellet was above 65% and the compressive strength was above 3 100 N. The process energy consumption was 17.05 kgce / t, which has reached first class level internationally.
