摘　　要：低温炭化是将压制球坯处于氩气气氛内缓慢升温,将基体石墨中的酚醛树脂等有机物裂解转化为具有较高机械强度的树脂炭,消除球形燃料元件压制过程中造成的内应力,初步加强球形燃料元件强度。本文研究设计了低温炭化设备的主要结构和功能参数,利用ABAQUS软件进行球形燃料元件温度的模拟计算。Low temperature carbonization is the slow heating of pressed billet in argon atmosphere,the cracking of organic matter such as phenolic resin in matrix graphite into resin carbon with high mechanical strength.Eliminate the internal stress caused by the pressing process of spherical fuel element and initially strengthen the strength of spherical fuel element.The ABAQUS software is used to simulate the temperature of spherical fuel element.
