THIELE
Induction-hardened tips
For extremely tough operating conditions – where there is a high rock content in the conveyed
product – THIELE can supply fight bars with induction-hardened tips. Additional heat treatment
increases the material hardness of the surface layer (which can be up to 10 mm thick) to 50 HRC
(about 1.700 N/mm²).
This process slows the rate of wear at the tips of the bars and therefore prolongs the life of the fights.
However, the decision to use induction-hardened tips requires careful consideration as bars of this type
can lead to increased wear at the pan profles.
