Numerical Simulations of Effects of Furnace Lining Radiation on 34CrNiMo6 Ingots
Original language description
The purpose of this study was to identify possible causes of formation of longitudinal surface cracks occurring during early stages of ingot forging. However, these cracks need not necessarily occur during forging or as a result of poor quality of the surface in metallurgical terms. Under certain conditions, they may form even as the the ingot is being heated in the furnace to the forging temperature. The cracks probably form within a few minutes of placement of the ingot in the furnace due to the temperature gradient which is most severe on the ingot surface. The numerical model was created to represent the case of placing two ingots in a furnace. Ingots cast from 34CrNiMo6 steel were used for simulation of a process where the ingot is cooled upon casting to no more than 600°C and then placed in a furnace at 1,100 - 1,200°C. Reference points were selected on the ingots either on or just below their surface. Numerical simulations in DEFORM and MSC.Marc/Mentat programs were used to anal
