Quenching is a critical step in heavy forgings production because it takes proper devices and solutions to ensure an appropriate cooling and, therefore, the obtainment of correct hardening effects. In this context, the use of the innovative spray cooling technique can be considered strategic for the reduction of inhomogeneity due to water quenching and for the improvement of the microstructural and mechanical homogeneity of forgings. In this work it was studied and designed a vertical spray quenching plant for the heat treatment of heavy forgings (shafts up to 150tons in weight and 16m in length), by using a pilot plant and numerical simulation as tools for the system calibration.
