The MSW RMS Roll Grinding Module can capture all key data associated with the re-grinding of rolls in preparation for the mill.
Roll grinding data is captured through an easy to use Roll Grinding Wizard. The Roll Grinding Wizard guides the operator through 5 easy steps allowing for quick entry of data at the end of every grind job. Capturing the data at the end of the grind job rather than at the end of the shift encourages greater reliability of data.
The Roll Grinding Wizard can capture critical measurement data such as the diameter, the finish ground roll profile, the worn (ex-mill) profile, the surface roughness and crack and bruise detection data.
Roll profile data can be captured from either the MSW Cadno Roll Measurement System or, optionally, from machine mounted measurement systems such as those commonly found on CNC roll grinding machines. (We can also develop custom interfaces to measuring systems as required.) Profiles can be inspected and validated against target cambers and tolerance limits set by management.
The Roll Grinding Wizard also captures data such as intended mill/stand, identity of partner roll, grinding machine and wheel, and operator name and shift. This data is captured via a simple 'Grinder's job card' similar to the paper-based forms that have been in use in most rollshops for many years (see screenshot).
The diameter of the ground roll is tracked and validated against previous grinds. Thus, for example, excessive stock-loss or 'growth' is flagged for explanation by operators. Similarly, if the roll diameter is outside of the permissible range for the selected mill/stand then an alarm is displayed to the operator.
The system is designed to track all stock loss against the roll. Thus, not only finished grind data can be captured but also partial grinds. For example, each grind of a backup roll that is ground in several stages can be captured. Similarly, staged reclamations of damaged rolls can be recorded.
The Roll Griding Module also provides screens for capturing measurements such as roll hardness, eccentricity and ovality. .
Roll Grinding Reports are produced by the RMS Reporting Module. These include: currently ground rolls; grinding history for a specific roll; roll grinding history for an operator; roll grinding history for a grinding machine; all grinds between user specified dates, grinds by shift etc.
