1 前言为了满足烧结点火工艺的要求,近几年投入使用的新型点火炉,均设置了点火段、保温段,有的还有预热段。由于新型点火炉在结构上往往采用一体结构,所以,为了保证各段均能满足所要求的热工制度,必须在段与段之间增设中间隔墙。烧结机点火炉系下部开放的箱形炉,因 1 Introduction In order to meet the requirements of sintering ignition process, in recent years put into use a new type of ignition stove, are set ignition section, insulation section, and some preheating section. As the new type of stove is often used in the structure of an integrated structure, therefore, in order to ensure that all sections can meet the required thermal system, you must add an intermediate partition between the segments. Sintering furnace at the lower part of the open hearth box furnace, due
