拱顶隧道窑改平顶Workbench数值模拟

Tunnel kiln structure vault to flat top workbench numerical simulation

隧道窑采用平顶结构对隧道窑烧成性能提升有很大帮助,但平顶在力学结构稳定性上远没有拱顶好,因此,一般采用吊挂砖方式来保证平顶炉窑结构上稳定。为此,采用Ansys workbench软件模拟隧道窑截面结构,采用无吊挂砖设计理念,通过不断调整上下拱顶高度、拱角内偏距,实现隧道窑内部拱顶变成平顶的目的,且不会大幅度增加内部耐火砖的耐压强度,使其处于有效的使用性能范围内,保证隧道窑的正常使用寿命。

The use of flat roof structure in the tunnel kiln is of great help to improve the firing performance of the tunnel kiln. However, the flat roof is far less stable in mechanical structure than the vault, so the hanging brick method is generally used to ensure the stability of the flat roof furnace structure. In this paper, ansys workbench software is used to simulate the cross-section structure of the tunnel kiln, using the design concept of no hanging bricks, by constantly adjusting the height of the upper and lower vaults, the internal deviation of the arch angle, to achieve the purpose of the internal vault becoming a flat roof, and will not greatly increase the compressive strength of the internal refractory bricks,so that it is within the effective performance range, to ensure the normal service life of the tunnel kiln.
