高炉无料钟多环布料参数的确定

Determination of Multi-ring Charging Parameters for Bell-less Top of Blast Furnace

在高炉串罐无料钟炉顶模型试验基础上，阐述了高炉无料钟炉顶多环布料基本参数确定方法和准则，建立了节流阀有效面积与其开度的回归方程以及料流量特征曲线方程，确定了多环布料溜槽倾角的档位，并建立了溜槽倾角档位的计算数学模型，为高炉无料钟炉顶多环布料实际操作和进一步理论研究提供参考依据．

The method and criterion for determining the basic multi-ring charging parameters are stated on basis,thus giving a regression formula in terms of the valid area of throttle value and its openingand a characteristic curve of material flow rate. Different inclinations of multi-ring charging chute are therefore determined and a mathematic model calculating the inclination of charging chute developed.
