Abstract

This study investigates the premature failure of the sidewalls related to a sintering pallet car of pelletizing plant of Gol-e-Gohar Mining and Industrial Company, Sirjan, Iran. At first, the extent of failure and the distribution pattern of common defects of the sidewalls are investigated through visual inspections. In this regard, the quality of the walls is classified in five different levels, and more than half of the existing side walls are randomly examined at different time intervals. According to the amount of the damage, they are regarded into one of the defined levels. Then, by performing tensile and stiffness tests, the mechanical specifications of three specimens of the sidewalls are extracted and presented. Next, the chemical analyses of the three samples are determined via quant metric tests and the results along with the standard ranges of the relevant alloy are compared. Some thermal tests are implemented on the samples to investigate the temporal oxidation reactions of the regarded alloys. To study the microstructures of the samples, including the type of granulation and chemical composition of different phases, metallographic tests are employed, and the results are represented in the form of images. In addition, the effects of other factors such as fuel consumed by burners as well as operating conditions on the life of the part are discussed. Finally, the data obtained by the mentioned experiments are analyzed in details, and the effects of the different factors on the premature failure of the side walls of the pelletizing machines are discussed.
