宝钢1号高炉操作炉型的控制

Control of Baosteel's No.1 BF Operational Profile

简要阐述了宝钢1号高炉并罐式无料钟炉顶布料偏析和铜冷却壁对操作炉型的影响，重点阐明了合理操作炉型的控制。1号高炉操作炉型控制的关键措施，一是保证合理的炉腹煤气量，合理调整送风制度，即炉腹煤气量指数控制在57．6-65．4m／min；风速270-275m／s，炉缸回旋区环带面积约占炉缸截面积的50％，炉身平均煤气流速在2．5-2．7m／s；二是探索合理的装料制度，确保焦炭平台宽度控制在2．35-2．55m，并采用溜槽和料罐周期性切换模式，以保持充沛的中心气流和合理的边沿气流。

It is described the influence of distributed burden segregation in bell-less top with parallel hoppers and copper cooling stave to the operational furnace profiles in Baosteel＇s No. 1 BF, and the control measures of suitable operational fur- nace profiles. The major ways to control the operational furnace profiles include ： （ 1 ） ensuring rational bosh gas volume and adopting rational blasting system with the aim of keeping the bosh gas volume index at 57.6 - 65.4 m/min, the blasting speed at 270 - 275 m/s, average gas flow-rate of furnace stack at 2.5 - 2.7m/s, and annular area of hearth raceway accounting for about 50% cross-sectional area of the hearth; （2） figuring out suitable charging sequence to form 2.35 -2.55 m coke plat- form width, and adopting periodic switch mode of chute and hopper for realizing sufficient center gas flow and rational periph- eral gas flow.
