对天津某钢厂3×1080m3高炉设计特点进行了总结分析。1080m3高炉采用双排矿槽、双料车上料、串罐无料钟炉顶、软水闭路循环冷却系统、“陶瓷杯+炭砖”复合炉底炉缸结构、新型旋流顶燃式热风炉、底滤法渣处理“、一级制粉+并列喷吹”喷煤等一系列先进实用工艺技术。一年多的生产实践证明,该设计为实现低耗、高效、长寿、环保的生产目标奠定了技术基础。
The design features of 3 × 1080m3 blast furnace in a steel plant in Tianjin were analyzed. 1080m3 blast furnace with double row slot, double car material, no bell of the top of the tank bell top, soft water closed loop cooling system, “ceramic cup + charcoal brick” composite hearth furnace structure, the new type of top cyclone hot air Furnace, the bottom of the filter residue treatment “, a milling + parallel injection ” PCI coal and a series of advanced practical technology. More than a year of production practice has proved that this design lays the technical foundation for achieving the goal of low consumption, high efficiency, long life and environmental protection.
