Laser roll alignment system
L-743 Hamar Laser

Maintaining precision alignments in steel plants has never been easy. Typical methods include optical telescopes and alignment templates for use with feeler gauges. These methods are very time consuming and are susceptible to significant errors, which is very important as Dave Spinelli, Team Leader, Dofasco, Inc. explains:

"Maintaining segment roll alignment and profile to a high degree of precision is critical to production of defect-free continuously cast slabs."

Our lasers offer the precision and timesavings to meet the ever-tightening tolerances of the steel industry. Our L-743 Ultra-Precision Triple Scan( Roll Alignment System is one of only 2 lasers in the world (L-733 is the other) to offer 3 automatically rotating laser planes, which creates a powerful tool to not only MEASURE but also FIX almost any misalignment problem in continuous caster mills.
