摘要
风口是高炉上损坏频率较高的部件,风口前端熔蚀是高炉风口损坏的重要原因之一.为此,用计算机模拟的方法研究了高炉风口的温度分布及杂质含量和水垢对水冷铜风口温度场的影响.模拟结果表明,纯铜风口温度分布较均匀,风口的最高温度为255℃;含有杂质元素的铜风口,其最高温度有所提高,但幅度不大;当形成水垢后,纯铜风口最高温度可大幅度提高.研究表明,杂质含量对铜风口的温度场影响较小,而防止形成水垢却是提高风口抗熔蚀能力的重要途径.
Tuyere is an assembly with the higher damage rate in a blast furnace. Erosion happening in the front of tuyere is one of the important reasons for damage of blast furnace tuyere. The temperature distribution of the tuyere as well as the influence of impurity and incrustation scale on the temperature field of the tuyere were investigated using numerical simulation method. The simulation result indicates that the temperature distribution is very homogeneous and the highest temperature is 255℃ in the copper tuyere. The highest temperature gets slightly increased in the tuyere with impurity, while the highest temperature gets significantly increased in the tuyere with incrustation scale. The re,arch shows that impurity content has a little influence on the temperature field of the tuyere. Preventing the formation of incrustation scale is the important method improving the erosion resistance of the tuyere.
