Definitions

the invention relates to a method for regrinding a roller with uneven wear and uneven temperature distribution over the length of the bale.
rollers must, for. B, cool in the air to full temperature compensation, which takes time and thus means large roller parks and capital tied up. These large roll parks must be available so that finished rolls are always available.
the invention has for its object to provide a method for regrinding a roller of the type mentioned, which manages without equalizing the temperature over the bale length of the roller before or during regrinding, which also significantly reduces the number of rolls of a flat rolling mill without that the necessary availability of finished ground rolls is reduced,
the task is solved in such a way that the different temperatures over the bale length of the roller on the grinding machine are measured by temperature sensors and entered into a computer which controls the infeed of the grinding wheel for a given roller diameter, roller material and desired grinding.
a roller 1 with any temperature distribution and any wear over its bale length was placed on a grinding machine 2 immediately after removal from a roll stand (not shown). Before the start of grinding, the temperature distribution over the bale length of measuring sensors 3 is measured. These temperature values and their position on the bale length of the roller 1 are fed to a computer 4, which forms a temperature profile of the roller 1 therefrom. Depending on the diameter entered into the computer 4 via the input device 5 at room temperature and the thermal expansion coefficient of the roller 1, the computer 4 determines the wear profile of the roller 1 to be ground and calculates the desired roller profile (hollow or spherical grinding with defined dimensions), which has also been entered. the necessary grinding curve and then controls the grinding wheel 6.
