根据有限元理论,采用ANSYS“生死单元”技术建立了铜冷却壁挂渣能力计算模型,计算煤气温度、冷却制度、炉渣性质、冷却壁镶砖材质等多种因素对铜冷却壁挂渣能力的影响,得出各因素对铜冷却壁挂渣能力的影响规律.煤气温度的升高将导致铜冷却壁挂渣能力呈指数衰减.冷却制度的改变对铜冷却壁挂渣能力的影响很微弱.炉渣挂渣温度的提升将使冷却壁挂渣能力增强,但渣皮厚度的稳定性较差.随着炉渣导热系数的上升,渣皮厚度均匀增大.镶砖热导率的提升可显著提升燕尾槽位置渣皮厚度.根据计算结果,本文提出了保证铜冷却壁稳定挂渣应遵循的几个原则.
According to the finite element theory, the calculation model of the scoria capacity of copper stave is established by ANSYS “Life and death unit ” technology, and the effects of gas temperature, cooling system, slag properties, The influence of various factors on the scoria ability of copper cooling wall was obtained.The increase of gas temperature will lead to the exponential decay of the scoria ability of copper cooling wall.The influence of the cooling system on the scoria ability of copper cooling wall is very weak.The slag The increase of temperature will increase the scoria ability of the cooling wall, but the stability of the scalp thickness is poor.With the increase of the thermal conductivity of the slag, the thickness of the scum increases uniformly.Improvement of the thermal conductivity of the tile can significantly improve the position of the dovetail Based on the calculation results, several principles that should be followed to ensure the stability of copper stave are put forward.
