MOLD CHECKER SLAB
MEASUREMENT OF MOLD SURFACEAND FOOT ROLLSBENEFITS
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 slab is a single device for several
different mold formats, as well as a single device for themeasurement of molds and mold foot rollers at continuous
slab casting machines. A particular version, Mold Checker,
is available for use in billet and bloom caster molds.

The operator only has to enter data like mold number, mold
width and number of casts and start the measurement. The
measurement itself is done completely automatically, so theoperator is not prevented from doing other tasks. For eachcross section more than 6000 measurement points aretaken in less than 6 seconds.
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
Transport and storage case
Measurement and visualization software(only executable program without source code)

FUNCTION
The Mold Checker slab consists of a measurement unitwith laser and the evaluation PC. The measurement unit ispositioned in the corner region of the mold. It automaticallycalibrates its position in reference to the mold and thevertical axis. A menu-driven HMI guides the operator
through the measurement of the mold.
