The object of this research is to detect the transverse and vertical heterogeneities which affect the sintering of the cake in order to provide the means of control required for increasing the uniformity of operation on commercial sinter strands. Three measuring systems have been developed to detect and quantify the vertical and transverse heterogeneities of sintering. They measure the cake temperature profile during sintering, the fumes' temperature and the flow rate of air drawn through the cake. The measurement of cake temperature profiles during sintering yields a good image of the progress of the sintering process. For practical reasons, this method remains limited to areas close to the pallet walls. However, the development of measurement pallets equipped for measuring the heat conditions of the fumes under the grid of sinter strands enables an overall picture of the state of the process for the whole strand to be obtained. Similarly, the measurement of the velocity profiles of the air drawn in above the cake provides another picture of the process, which makes it possible to locate running heterogeneities further upstream relative to the flame front. Numerous measurement campaigns have confirmed that transverse and vertical heterogeneities affect the sintering. Different means have been applied to reduce some of the heterogeneities detected.
