摘　　要：针对目前低压铸造机保温炉在工作中受高温和内部压应力的作用下,坩埚所受应力大小不易求得的现象,设计了一种坩埚式保温炉及其密封方式。通过前期数学建模求得保温炉在铸机工作过程中所受最大热应力。然后借助ansys workbench有限元分析软件,对坩埚和炉盖进行热力耦合分析,求得保温炉最大应力以及最大变形量和最大变形部位。并确定了保温炉密封圈的预留尺寸值。根据仿真分析结果和设计尺寸制作了保温炉的样机,并对其进行试生产试验,通过加压曲线的吻合程度,验证了坩埚的密封性能。According to the effect of the high temperature and the internal pressure stress in the operation of the LV casting machine.The maximum thermal stress of the insulation furnace is obtained by early mathematical modeling.Then,with the help of ansys workbench finite element analysis software,the crucible and furnace cover can obtain the maximum stress and maximum deformation of the insulation furnace.The reserved dimension value of the thermal insulation furnace sealing ring is also determined.According to the simulation analysis results and the design size,and verify the sealing performance of the crucible through the consistency of the pressure curve.
