不采用传统接触力模型自下而上的高炉料面形状计算方法,而是根据土坡力学颗粒物质堆积理论,提出了新的基于堆积法的高炉料线形状融合计算方法,直接对料面形状进行计算.围绕高炉多环布料的炉料堆积特点,结合炉顶六点阵列雷达,获得了料面形状计算的边界条件,弥补了传统料型计算靠十字测温加机械探尺的经验估算.新方法通过高炉布料规律及炉料颗粒的物理堆积插值方法,采用贝叶斯数据融合方法和分段三次Hermite插值,结合布料体积约束条件,完成了理论计算与测量修正的结合.实测结果表明:料面形状融合法比传统单独的料面估算法,测量精度提高4.8%,料面分辨率提高27.2%,使布料控制可以更加精准和有针对性.
Instead of using the traditional contact force model to calculate the bottom surface shape of the blast furnace bottom surface, a new method of calculating the shape of the blast furnace wire based on the pile-up method is proposed according to the theory of soil bulk material particle accumulation. And the calculation was made.According to the characteristics of charge accumulation of blast furnace multi-ring fabric and the combination of roof six-point array radar, the boundary conditions of material surface shape calculation were obtained, which made up the empirical estimation of traditional material type calculation by cross-temperature measurement and mechanical probe. Method The combination of theoretical calculation and measurement and correction was completed by using the blast furnace cloth rule and the physical pile-up interpolation method of charge particles, using the Bayesian data fusion method and the sub-cubic Hermite interpolation, combined with the cloth volume constraint conditions. The measured results show that: Compared with the traditional single surface estimation method, the shape fusion method improves the measurement accuracy by 4.8% and the material surface resolution by 27.2%, which makes the fabric control more precise and specific.
