Six heat treatment processes-longer life

Fenghe’s team of engineers pays attention to the impact of the heat treatment process of the slewing ring on the life of the slewing ring, and continuously improves and optimizes the process level.

Rough quenching and tempering (quenching + high temperature tempering)
Raceway surface induction hardening (medium frequency) + tempering (low temperature)
If it contains gears, quench the gears of the slewing ring, namely: induction hardening (medium frequency) + tempering (low temperature) of the gear surface
