Simulation of Quenching of Ball Bearing Rings Made from 100Cr6 Steel

Popis výsledku v původním jazyce

Thermal regime simulation with varying hardening temterature of three modes of oil quenching of ball bearing rings made of 100Cr6 steel was caried out in Sysweld program, based on finite element analysis. 3D model was prepared acording to manufacturing documentations of rough machined external rings. Hardening temperatures used 830, 850 and 870 degree celzius. As result complete graphical description of temperature, phase composition and hardness depending on time of quenching has been obtained. The results were compared with experimental heat treatment caried out with the same parameters. Comparison showed slight differences in hardness after quenching. In range of hardening temperatures applied, the observed microstructure consists of undisolved secondary cementite the volume fraction of which is depending on a number of parameters like heating speed, hardening temperature, holding time etc. This parameters have direct impact on microstructure and hardness after quenching. Sysweld so
