炉缸工况对高炉操作极为重要,如炉缸工作不佳,则会带来如下后果: ①成为限制提高生产率的关键;②使炉况不稳;③影响正点出铁和给炉前工作带来困难;④引起风口烧坏;⑤导致炉缸烧穿,被迫降低生产率,甚至停炉修理。炉缸的工作状况目前主要根据外部征兆(如炉缸壁和炉底的温度、出铁次数、铁流大小和铁水温度等)来判断。但是不同的炉缸工况却往往会呈现相同的征兆,造成难以正确判断,甚至出现失误,为此需从炉缸内部取得信息进行研究。本文所述是采用由一
The hearth operating conditions are extremely important for the operation of the blast furnace. If the hearth works poorly, it will bring the following consequences: ① become the key to limit the increase of productivity; ② make the furnace unstable; ③ affect the punctuality and supply the working zone To cause difficulties; ④ cause the outlet to burn out; ⑤ lead to burn through the hearth, forced to reduce productivity, or even shut down to repair. The working condition of the hearth is mainly based on the external symptoms (such as the temperature of the hearth and bottom of the furnace, the number of the irons, the size of the iron stream and the temperature of the molten iron, etc.). However, different hearth conditions tend to show the same signs, resulting in difficult to judge correctly, or even mistakes, for which it is necessary to obtain information from the hearth to study. This article describes the use of a
