高炉内炉料下降和煤气流的上升构成逆流运行过程。以软熔带为界,上部有固、气相存在,下部有液、固、气三相共存。在两态或三态的运动中,伴随着错综复杂的物化反应。而煤气是能量传递和热交换的介质,它的分布直接关系到高炉内的传质、传热、传动量过程进行的程度。因此,高炉截面煤气流的合理分布是强化高炉冶炼的关键,也是高炉经济操作的基本条件之一。多年来,国内外,对大型高炉内煤气流分布的研究颇为引人注目,其研究的方法主要是通过理论计算、数理统计、冷态解体、模型研究和直接测试等方法。本文应用数理统计和径 Blast furnace charge down and gas flow rise constitute the counter-current operation. To the soft melt zone for the community, the upper part of the solid, gas phase exists, the lower part of the liquid, solid, gas coexist three phases. In the two-state or three-state movement, accompanied by a complex physical and chemical reactions. Gas is the medium of energy transfer and heat exchange. Its distribution is directly related to the extent of mass transfer, heat transfer and transmission in the blast furnace. Therefore, the reasonable distribution of blast furnace gas flow is to strengthen the key to blast furnace smelting, blast furnace economic operation is also one of the basic conditions. Over the years, the research on gas flow distribution in large blast furnace has attracted considerable attention both at home and abroad. The research methods are mainly through theoretical calculation, mathematical statistics, cold disintegration, model research and direct test. This article applies mathematical statistics and paths
