Why Are We Hardening the Necks of the Rolls?
Induction hardening of the neks is necessary, as the roll necks often serve as bearing points where higher hardness is required.
Induction hardening of roll necks with uniform treatment along the entire length, including at the point of transition.
Our induction hardening machines for necks ensure uniform hardening along the entire length of the roll neck, as well as at the contact point between the roll neck and the roll body—point of transition or radius. Optimal hardening at the contact point is achieved through a second quenching ring, which has its own drive, independent of the inductor.
