Gaptor® roll checker

Gaptor® – the innovative strand condition roll checker has become an integrative element of quality control in modern continuous caster technology.

Gaptor® enables the control of all potential error sources and provides detailed information about the condition of the strand guidance. The survey of all quality relevant parameters like roll gap, roll rotation, roll bend and water spray allows for preventive maintenance actions which account for cost reductions.

Gaptor® collects all necessary data within one measurement cycle. This avoids loss of time and difficult steric configurations as in manual measurements. The results of the periodic measurement runs can be compared. The factory operator is consequently in the position to plan for maintenance actions and replacement of a section of the caster machine.
