100吨级铁水罐温度场分析
|
摘要
铁水罐是钢铁工业的重要设备,其温度场的分布对铁水罐的使用寿命有重要影响。本文通过有限元软件ansys,对耐火砖不同厚度及不同材料参数情况下的温度场进行仿真,并分析了铁水罐各种参数对铁水罐温度场的影响。分析结果表明:耐火砖厚度的减小会使径向温度梯度增加,耐火砖导热率的增加会使罐壁外表面温度上升,合理的选择耐火砖厚度和导热率可以有效地减小温度梯度和表面温度,延长铁水罐的使用寿命。
Hot metal ladle is the important equipment in iron and steel industry, and its temperature distribution has a great influence on its service life. Ansys software was used to simulate the temperature field of ladle in which firebricks were under different thick and materials, and the influence of various parameters on temperature field was analyzed. The analysis showed that, the decreased thickness of firebrick increased the temperature gradient of in the radial direction, and the increasing thermal conductivity caused the rising temperature on outside surface of ladle wall. Choosing proper thickness and thermal conductivity of the firebrick can effectively reduce temperature gradient and surface temperature, which help to extend the service life of ladle.
