通过在高炉的缩小模型内进行的模拟布料试验(原形有效容积V=1360m~3),研究了无料钟高炉布料时,炉料径向粒度分布与布料操作参数之间的关系,通过正交回归、最优化等一系列数学处理,得出了无料钟炉顶高炉烧结矿粒度在炉喉径向分布的一般规律,并建立了模拟布料的回归数学模型。 该数模较好地反映了装料方式与炉料粒度分布之间的关系.粒度分布由该数模的15个回归方程给定;反之,确定或知道了粒度分布,通过数模能为生产提供优化操作的装料方式。
The relationship between the radial particle size distribution of the charge and the operating parameters of the fabric when the material is discharged from the blast furnace is studied through a simulated fabric test (prototype effective volume V = 1360 m ~ 3) conducted in the reduced model of the blast furnace. By orthogonal regression , Optimization and a series of mathematical treatments. The general rule of the radial distribution of the sinter grain size in the blast furnace without blast bell was obtained, and the regression mathematical model of simulated cloth was established. The numerical model better reflects the relationship between the charging method and the particle size distribution of the charge.The particle size distribution is given by 15 regression equations of the model; conversely, the particle size distribution is determined or known, Optimize the operation of the loading method.
