Abstract: Results of direct cooling tests of drop forgings made of UHSS steel grade 4130 are presented. The studies include determination of forging and direct cooling conditions in aspect of realization of thermomechanical treatment directly after forging oriented at producing required microstructure and mechanical properties. For estimation of forging temperature and most favourable cycle of cooling, experimental tests of forced-air cooling in laboratory conditions were carried out with application of controlled-cooling line, which unlike the most of the industrial conveyor, is facilitated with automatically controlled system. The results have been implemented into industrial forging cycle, conducted with use of the same portable cooling device. Obtained samples underwent examination with metallographic work and tensile testing, which confirmed possibility of direct cooling with forced air and allowed formulation of guidelines for improvement of effectiveness of the cost-effective thermomechanical treatment.
