Quad Infotech has started its implementation of QMOS MES system at Gerdau’s Midlothian plant


Quad Infotech has begun implementation activities at Gerdau’s Midlothian, Texas facility. The Midlothian plant is a large facility, equipped with two Electric Arc Furnaces (EAF), ladle refining stations, and three casters feeding three rolling mills. The rolling mills produce long large section, medium section structural and long bar products. QMOS will play an essential role in addressing the challenges of scheduling, billet inspection, failure analysis, corrective action placement and reporting key performance indicators in all areas of operation. QMOS will also allow Midlothian facility to perform post processing functions, designed with full quality checks in place and seamlessly integrated with their SAP Enterprise Resource Planning (ERP) tool.

Some of the highlights of this implementation include:

  • Multi caster and multi EAF schedule and operation visibility by station
  • Advanced Equipment Management System (EMS) tracking all equipment related parameters including ladle residency time at the preheater or repair bays
  • Large section mill scheduling tool, embedded with billet optimization logic to satisfy multiple orders and minimize metallic loss in the rolling mill
  • Hot and cold billet inspection recording and analysis tools
  • Management and tracking of planned scheduled billet moves within the billet yard
  • ASTM mandated management of merged billet batches
  • Roll inspection and analysis screens
  • End to end billet tracking, identifying each bar on the cooling bed by heat, strand and cut
  • Corrective action identification and execution tool for finished and semi-finished goods

The advanced data analysis tools in QMOS, MI and APEX as well as its standard and custom production and KPI reports provide the Gerdau plant with great opportunities for targeted process analysis and performance evaluation.
