Electromagnetic - Temperature calculation

 

Description: The use of electromagnetic heating technology, the heavy rail temperature heating. The model is an electromagnetic - temperature coupling model. According to "60 kgm rail dimensions" to establish a geometric model, the specific dimensions are as follows: contains the air field.
