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.

英文摘要：

A model for calculating the adherent dross capability of copper cooling staves was founded by ANSYS birth- death element technology based on the finite element theory. The influences of gas temperature,cooling methods,slag properties,and cast-inbrick material on the adherent dross capability were evaluated and the corresponding influence rules were acquired. The calculation results showed that the adherent dross capability of copper staves exponentially decreased with increasing gas temperature. The adjustment of cooling methods could hardly change the adherent dross capability. The promotion of slag＇s adherent temperature enhanced the adherent dross capability while weakened the stability of slag layer thickness. The improvement of slag＇s heat conductivity increased the slag layer thickness linearly. The increase of heat conductivity of cast-in-bricks could significantly thicken the slag layer of the dovetail groove area on the copper stave. According to these calculation results,several principles were proposed to ensure the copper stave working steadily.
