Rolling mills, especially the ones producing coils often cut billets right out of the furnace and roll the cut pieces for sizing purposes. The new PRR billet cut functionality provides the ability to track each of these cut pieces, and properly account for the time and tonnages.

Prior to this, QMOS users would have to turn off the detection of billets in PRR as they rolled the cut pieces. This often led to data inaccuracies with operators forgetting to turn the detection back on. Another major side effect of this method was recording skewed rolled tonnages with incorrect timings as the QMOS was unable to record production information against a single billet that was cut to multiple pieces and rolled separately.

With Billet Cut, users now have an easy and intuitive graphical interface that allows them to set a billet cut scenario with ease within PRR. Various pre-defined cut scenarios can be picked, such as 50-50 cut, 67-33 cut, 75-25 cut, or 25-25-50 cut, etc. As the cut pieces of the billets are rolled, they will be displayed on the screen as individual bars.

QMOS can thus automatically adjust the tonnages of the bars from these cut pieces as per the cut scenario chosen. Each of these pieces may be set as Sizing, Cobble, Prime, etc as needed, and they will be reflected accurately in the screens and reports, preserving the integrity of the data.

The Billet Cut has also been designed with two strand mills in mind, and the simple interface allows users to switch pieces of cut billets to be rolled in the opposite strands with an easy drag and drop feature. Therefore a billet with its first piece rolled in one strand can have the latter pieces rolled in the other.

The feature offers accurate tracking of the rolling of bars for the billets that are cut up, providing extra flexibility in recording data.
