Induction Hardening of mill rolls

Application: Hardening

Software: ELTA 6.0/5.5

Type: Practical experience

Hardening of mill roles is one of very important induction technologies. There are several technologies of induction treatment of rolls: preheating, stress relieving, surface hardening and tempering. One of the technologies includes roll hardening using two inductors.
It is very important to predict the results of design especially for big rolls, which can weigh more than 20 tons and cost more than 50,000 Euros each. (more)







ELTA 5.5 (6.0) was used to find a possibility to improve the heater.
