Shearing

After hot leveling and cooling, the mother-plates are usually sheared and edge trimmed to obtain the final width and length. After shearing, the plates may be quenched, normalized and leveled for improved flatness. Here is an important point for decision making and routing. For instance, flat plates should not be leveled. Plates with bad flatness should not be sent to quenching. Wrong decisions in this point are really costly, why a VeriFlex system in this position can easily be motivated.

A VeriFlex system can also support down-stream cutting where the final plates have to fulfill the requirements by “virtually” cutting them in the software before the real cut.

In addition to this, measured data can be fed backwards to rolling and hot leveling to improve the incoming flatness statistically over time. Data can also be sent forward to downstream processing lines (levelers) as recipes. Normally I-unit profiles are used for this, which can be utilized to pre-set the levelers. After a degree of practice, it can also be possible to judge whether or not a plate can be leveled flat.
