死料堆是高炉炼铁从侧向鼓风的必然产物。在死料堆内很少或无气体流动时,对流动的煤气而言,它是个“死区”。自然这里的焦炭反应不活跃,更新缓慢。经试验确定,死料堆是抛物线型的二次曲线。当软熔带形状及位置一定时,若死料堆增大,则它与软熔带间的通道变窄,煤气流动阻力损失增加,致使高炉难以接受风量。因此,死料堆的形状和大小对高炉生产至关重要,它是高炉上、下部调剂的综合反应,研究死料堆的成因和变化规律 Dead stockpile blast furnace is inevitable product of lateral blasting. It is a “dead zone” for flowing gas when there is little or no gas flow in the heap. Natural coke reaction is not active here, update slowly. After testing to determine the dead stock reactor is a quadratic curve of the parabolic type. When the shape and location of the reflow ribbon is fixed, if the dead-material pile increases, the passage between it and the reflow ribbon will be narrower and the loss of gas flow resistance will increase, which makes it difficult for the blast furnace to accept the air volume. Therefore, the shape and size of the heap reactor is crucial for blast furnace production, which is the integrated response of the upper and lower parts of the blast furnace to study the causes and variation of the heap reactor
