自对高炉实施解体调查后,们发现高炉内炉料的下降过程并不象以往的超越理论所描述的那样,矿石与焦炭在下降过程中逐步混合,甚至发生矿石超越现象,而是以层状结构,即焦炭和矿石各自呈层状,从炉喉徐徐降入炉缸。在矿石熔化和滴下之前,可由剖面上数出它们的层数。因此料层的厚度和形状对炉内气流分布及其能量利用有着极为密切的关系,近年来推广的大料批分装操作制度取得的成效就是一个明显的实例。故而,高炉操作者一直期望能有一种在线测 Since the disintegration of the blast furnace to investigate, they found that the furnace blast furnace down process is not as the past beyond the theory described as ore and coke in the descending process of the gradual mixing, or even ore overrun phenomenon, but the layered structure , That coke and ore are layered, slowly from the throat into the hearth. Before the ore melts and drips, its number of layers can be plotted in section. Therefore, the thickness and shape of the material layer have a very close relationship with the distribution of the gas flow in the furnace and the utilization of its energy. In recent years, the achievements made in popularizing the operation system of large batch of bulk materials are an obvious example. Therefore, blast furnace operators have always expected to have an online test
