UHP电弧炉炉壁衬合理厚度的探讨

摘要

通过分析UHP电弧炉内热流强度产生的热冲击应力对炉衬使用寿命所产生的影响,提出了通过计算炉壁衬极限升温速度,结合热阻校验的方法,计算UHP电弧炉炉壁衬合理厚度.经过实际工程应用证明该方法所计算炉壁衬厚度比较合理.%The influence of thermal shock stresses generated by the heat shock intensity in UHP EAF to the life of furnace wall lining was analyzed. Then proposed a method that can calculate the furnace wall lining proper thickness by calculating the limiting heating-up velocity of furnace wall lining and combining the verifying of the thermoresistance. It shows that this method is effective in the practical application.
