摘　　要：以包钢长材厂蓄热式加热炉为研究对象,利用Ansys软件采用k-ε湍流模型、P-1辐射模型等,模拟了采用交错燃烧组织方式加热炉内各物理场分布情况。发现该种燃烧方式下,炉内流动涡流运动明显加强,有利于燃烧的混合和组织。但出口附近的回流造成燃烧短路,高温烟气不易达到炉膛中心,易造成炉内温度不均匀,氧气浓度相对较高不利于钢坯生产,因此该平顶、平底炉型采用交错换向燃烧有待于进一步实践验证。The regenerative heating furnace of tlie long material factory was taken as the research ob-ject, used the model of ＇ - $ turbulence model and P - 1 radiation model using Ansys software,andsimulated the distribution of the physical field in the furnace with staggered comis found that the flow vortex motion in the furnace is obviously enhanced undAnd it is also conducive to the mixing and organization of the combustion. But the reflow caused bycombustion short circuit near the exit. High temperature flue gas is not easy to reach the center of thefurnace and cause the furnace t uneven temperature distribution. Oxygen concentration is relativelyhigh,which is unfavorable to billet production. Therefore,the flat roof and flat hearth type adoptedstaggered reversing combustion need to be further verified.
