摘　　要：焦炭在干熄炉预存段内料面形状的分布对焦炭的下降和焦炭与冷却气体间的换热具有重要的影响。考察了3种料钟布料情况,从实验和理论两个方面对不同料线深度条件下焦炭堆积形成的料面形状进行了研究。理论计算结果与实验数据吻合较好,验证了数学模型的正确性和实验的可靠性。The distribution of coke bulk shape in CDQ Pre -chamber has the important influence on descending behavior of coke and heat exchange between coke and cooling gas. Three coke distribution cases by bell are investigated, the coke shape formed during coke deposit under the condition of different material depth is studied in experimental and theoretical aspects. The theoretical calculated result is better coincided with experimental result, it proves the correctness of mathematical model and experimental reliability.
