MOLD CHECKER LONG
MEASUREMENT OF MOLD SURFACEAND FOOT ROLLS FOR LONGPRODUCT CASTING MACHINES
BENEFITS
By measuring the 3-dimensional contour of a mold, it ispossible to observe the wear during lifetime, estimate thelifetime of the mold and to measure and properly adjust
foot rolls. Correctly adjusted mold tapers minimize theprobability of breakouts. By knowing about scratches
and the deviation from the set point geometry, thebest time to exchange mold plates can be determinedin order to prevent breakouts and save money. Newestlaser technology makes it possible to acquire all the moldrelevant data with only one measurement device thatmeasures contactless and fully automatically.
FIELD OF APPLICATION
Mold Checker is a single device for several different moldformats, as well as a single device for the measurementof molds and mold foot rollers at continuous slab castingmachines. A particular version, Mold Checker slab, isavailable for use in slab caster molds.

Optional
For foot roll measurement, the measurement unit moves
further down and measures the position and alignment ofthe foot rolls. The measurement data are storedautomatically, so analyses can be done at a later date.
PRODUCT STRUCTURE
Measurement unit with calibration ring, the unit’s basewill be adapted to fit the customer molds
10 m connection cable between evaluation unit andmeasurement unit
Evaluation unit (laptop) with software to control themeasurement unit and for data evaluation
Case for measurement unit

FUNCTION
The linear unit stops the laser at user-defined depths of themold and measures each section by rotating the laser. The
sections to be measure can be defined individually in stepsof 5 mm. Optimal performance is ensured by using smallsteps (e.g. 5 mm) in interesting regions (meniscus, bottomof mold) and bigger steps (e.g. 50 mm) in the regions inbetween.
