两排氧枪角度设置对大型底吹炉流动特性的影响
Effect of angle setting of two rows of oxygen lances on flow characteristics of large bottom-blown furnaces
摘要
Abstract
The simulation model of oxygen bottom-blown furnace was established at different oxygen lance inclinations angles and angular spacings to analyze the effects of different operating conditions on the melt flow characteristics.The results show that the influence of the angular setting of the two rows of oxygen lances on the flow characteristics in the bottom-blown furnace is mainly reflected in the furnace diameter direction.The angle of the oxygen lance inclination will have an"offset"effect on the spatial position of the core stirring zone,controlling the degree of offset of the core reaction zone to the furnace wall on the side where the oxygen lance is located.The angular spacing will have a"dispersion"effect on the stirring state of the core stirring zone,controlling the degree of dispersion of the core stirring zone formed by the stirring source.In order to better regulate the pneumatic stirring characteristics of the melt pool of a large bottom-blown furnace,it is more reasonable to set the angle of the two rows of oxygen lances to a combination of 0° and 15°.It has a better pneumatic stirring strength and gas dispersion effect in the melt bath,which in turn improves the melting efficiency and does not produce malignant spattering of the melt.关键词
