摘要
钢包是冶金工业的重要设备,其内衬的热机械应力分布对寿命有至关重要的影响,其寿命的长短直接影响钢铁企业的经济效益。建立了基于有限元法的钢包二维模型,并对工作层材料的导热率、热膨胀系数、弹性模量及其厚度对钢包应力场的影响因素进行了研究。计算结果表明:随着钢包内衬工作层材料导热率的增大、热膨胀系数的增大、弹性模量的增大和厚度的减小,钢包等效应力增大。
Ladle is an important equipment of the metallurgical industry,distribution of thermomechanical stress in linings has essential influence on its life,and the size of its life-span influences the economic benefits of the iron and steel enterprise directly.Two-dimensional model of ladle based on law of finite element method is built,the influence of from thermal conductivity,thermal expansion coefficient,elasticity coefficient and thickness of work lining on ladle stress field are discussed.The calculation results indicate that stress increases with the increase of thermal conductivity,thermal expansion coefficient and elasticity coefficient and decrease of thickness.
