Asymmetric Cooling Process for Towing Hooks Forgings
The essence of the new solution is the implementation of asymmetric cooling technology for forgings made of 38MnVS6 and 30MnVS6 steel in order to homogenize the mechanical properties through precipitation hardening. The developed process for forgings with significant cross-sectional asymmetry was pr...

| description | The essence of the new solution is the implementation of asymmetric cooling technology for forgings made of 38MnVS6 and 30MnVS6 steel in order to homogenize the mechanical properties through precipitation hardening. The developed process for forgings with significant cross-sectional asymmetry was practically implemented in the conditions of the Kuźnia Matrycowa in Lublin. The heat treatment conveyor using the given solutions is 10 m long, and the time needed to complete the controlled cooling of forgings, divided into two zones, is 7-10 minutes. Cooling curves are controlled by a fan system with individual measurements and air flows in each section. The obtained results indicate the validity of using this solution, especially in terms of reducing the grain size and increasing the mechanical parameters of the products, including the impact strength parameter, which is crucial when accepting towing hooks manufacturing. |
