Mill Roll Hardening

Induction heating is the process best suited to the surface heating of steel parts. This technique has many applications, especially in hardening rolling mill rolls which it is particularly effective. The continually expanding development of cold mills, in which the rolls are subjected to high stresses, is being pursued in parallel with research to obtain rolls with high strength and resistance to surface wear. Induction heating has greatly contributed to improvements in hardening depth with the subsequent improvement in the distribution of residual stresses.

This has increased roll life and reduced the number of retreatments that rolls have to undergo before completely wearing out.

The 50-year experience of INDUCTOTHERM contributed largely to the world-wide development of the induction hardening of forged rolls.

Inductotherm MTCL mill roll hardening machines are in operation in France, Great-Britain, Germany, Sweden, Japan, USA, China, Brazil, Mexico, and South Africa.
