Simulation studies on the quenching process in QST steel rounds
Simulation, quenching, rounds, heat transfer coefficient, QST
The paper discusses the quenching simulation of various sizes of rounds to assess the inter-relationship between the size of rounds, the heat transfer coefficient and the volume fraction of a given steel composition precipitating below Ms (martensite start) temperature. Finite element method (FEM) was used for heat transfer simulations. Parametric studies were carried out to analyze the heat transfer coefficient necessary for achieving different volume fractions of precipitates below Ms temperature.
Such an analysis can be used as a tool in the design of cooling systems for achieving higher grades of quenched and self tempered (QST) rounds, as well as for selecting those sizes of rounds which, under a given cooling regime, are suitable for this objective.
