Abstract
The invention relates to a process for regulating the lubrication of the working face of the rolls of a continuous strip casting machine. The process is characterized in that, in order to operate the machine at the highest possible speed while avoiding excesses of lubricant or sticking phenomena, at least one beam of coherent light is directed on to the working face of each of the rolls or on the each of the faces of the strip or on to the face of a roll and the face of the strip opposite to said roll, the values of the mean strength and/or the frequency of the variations in the beam reflected by said faces are measured, said measured values are compared to values in reference intervals, and the speed of rotation of the rolls and/or the lubricant flow rate is adjusted in dependence on the location of said values with respect to said intervals. It finds application in all machines for casting material between rolls in which there is a wish to achieve a maximum level of productivity.
