Heat Treatment for 20NiCrMo7 and 15CrNi13 Steels Used on Construction of Extralarge Bearings
Journal Title: RECENT - Year 2010, Vol 11, Issue 29
Abstract
This paper give an overview to the processes appeared in deep carburizing of elements produced with 20NiCrMo7 and 15NiCr13 steels used in construction of hollow rollers. The used software is specialized to simulate heat treat process of carburizing in controlled atmosphere with different level of carbon potential. Experimental measurement of temperatures and carburizing size, during heat treatment, was made as part of this study and confirm theoretical results to validate the software predictions. Mathematical model is based on mass transfer law and Fick second law and the algorithm was implemented in Visual C++. The objective for this work was to develop a strategy for the process control and optimization of heat treatment process.
