<p>PURPOSE:To measure a roll shape in the inline state with a high precision, by using an optical beam as the measurement reference and moving a measurer while bringing the measurer into contact with the surface of the roll and detecting the extent of movement in the radius direction by an optical position sensor attached to the measurer. CONSTITUTION:A moving material 22 is provided slidably on a guide rail 21 parallel with a roll 11 of a rolling mill, and a measurer 29 is attached to the moving material 22. An optical position sensor 31 consisting of an element which generates a signal of the rectangular coordinate system on a basis of the position of a spot is attached to the left face of the measurer 29. The sensor 31 is irradiated through lenses 33, 34, and 35 with a laser beam to be a measurement reference from a laser beam generator 32. In case of measurement, the light spot on the sensor 31 is moved on a two-dimensional plane when the measurer 29 is slided along the surface of the roll, and the coordinate signal is inputted to an operation controller 54 through a signal processing circuit 51 and is converted to the radius of the roll and is plotted on a plotter 56. Thus, the roll shape is measured on the inline state with a high precision.</p> |
