Hot Roll Grinding Precision Roll Grinders

May 05, 2021  Hot grinding is often the solution to production challenges caused by excess distortion as a result of high-temperature operations. Rolls are carefully examined and then heated to operating temperature — up to 600 degrees Fahrenheit. Then, we grind them to PRG accuracy for a roll that starts up and operates just the way you need it to ...

Thermal Compensation of Work Roll Grinding in Hot Strip Mills

For the work roll hot-grinding with contour com-pensation, the grinding curve was modified based on the measured surface temperature of the work roll before the grinding operation. After the temperature of the ground work roll cools down to the uniform tem-perature along the work roll axis, the work roll crown can be achieved as the designed crown.
