摘　　要：武钢炼铁厂在无料钟炉顶布料控制改造中采用分段线性化/经验公式法描述流量 -开度曲线 ,在恒料流控制中采用流量反馈改进下料门控制 ,利用折返布料完善现有布料方式 ,显著提高了炉顶布料的精度,增强了布料方式的灵活性与多样性 ,并因此提出了按角度布料的新模型。在炼铁厂2 #、4 #、5 #高炉运用中 ,取得了明显的效果 ,2000年度3座高炉的各项冶炼生产指标均达到历史最好水平。Flow opening curve is described by section linearization/empirical formula method during the reformation for bellless top distribution control of Ironmaking Plant in Wuhan Iron and Steel Group Co. Discharge gate control is modified by flow feed back in constant flow control. Distribution mode is improved by reciprocating distribution. The results show that the precision of top distribution is largely enhanced and the flexibility and variety of distribution mode are improved, and thus a new model of distribution based on angle is presented. The remarkable effect is obtained during application. The production indexes of BF reached the historical best level in 2000.
