AbstractFerrite grain size strongly influences the mechanical properties of steels. In hot rolled steels, the ferrite grain size is determined by the austenite microstructure during the finish rolling, and by the rate of cooling through the transformation temperature range. A sensor to monitor phase transformations and grain sizes in strips during hot rolling would allow to control the process parameters, optimize the ferrite grain size, and better achieve the desired mechanical properties. Unfortunately, such a sensor is presently not available in hot strip mills.
