STRAND CHECKER
ACCURATE AND EASY ADJUSTMENT
OF CONTINUOUS CASTING SEGMENTS
BENEFITS
Strand Checker supports casting plant operators in several
tasks like checking the gap, alignment and rotability of rolls.
Spray water nozzles are checked for operation and nonperformance. The frequent use of the fully automaticallymeasuring Strand Checker enables optimum use andmaximum lifecycle time of continuous casting machines.
Internal quality of slabs can only be guaranteed with proper
adjusted caster rolls

The Strand Checker offers a 3 step software: Measurement
software continuously measures and stores measured
values for the automatic transfer via WLAN to the server.
Converter software converts measured values to “real” gap,alignment, rotability and spray water values saves data intothe database. The analyzer software can be installed on
PCs of everyone interested in Strand Checker data. Only
connection to database is necessary.

FIELD OF APPLICATION
Strand Checker can be used for all types of continuous slab
casting machines from 80mm thickness on.
FUNCTION
The Strand Checker is mounted on the dummy bar. The
bearing clearance of measured rolls is compensated bypressing the Strand Checker against rolls using nitrogengas springs. The nitrogen gas springs can easily be
activated and deactivated. The power supply of theelectronic processing unit and signal storage of all
sensors is provided by batteries. Data is transferred to theevaluation unit using WLAN.

min. 75%• DynaGap connection
Operator can send measurement values
from Strand Checker with 1 click to segment
controller for gap calibration.
• Nitrogen springs
Force of springs can be switched on/off on
demand.
Easier entering of Strand Checker on bottom
feeding caster.
• Same sensors for gap and alignment sensors
Easier and faster calibration (without
disassembly of Strand Checker).
Less spare parts.
• No sensors on bottom side
Sensors cannot be damaged when StrandChecker is placed down.
We can measure caster with non-oppositerolls.
• Microphones for spray water detectionMore robust and reliable system for spraywater detection.
