Temperature Monitoring in Primary Metals Processing

Hot Rolling Mills

In metalworking, rolling is a metal forming process in which metal stock is preheated up to 1300°C (2400°F) and passed through rollers to reduce thickness. Hot rolling processes include pre-heating furnaces, scale breakers, slab scale, rough stand, finishing stand and cooling lines.

Application Need 

Monitor the temperature in comparison to the recrystallization temperature to ensure product uniformity.

Benefits to the customer 
  • Monitor product (slab or billet) temperatures and verify the furnace control mathematical model, based on the thermal profile results
  • Use IR spot pyrometers to ensure uniformity of temperature to reduce wear and tear on rollers and avoid excessive maintenance costs
  • Use IR scanners to identify surface defects and avoid product quality issues and high reject costs
  • Ensure optimum process efficiency, minimize energy consumption and maximize throughput
Thermal Profiling Systems
  • Datapaq TP3 data logger provides up to 20 measurement channels, allowing comprehensive monitoring over entire slab/billet throughout entire preheat furnace
  • High performance dual phase thermal protection provides system safety even through the most hostile preheat furnaces
  • Insight™ Furnace Tracker software provides data review and analysis to allow efficient and accurate validation of furnace control mathematical models
Infrared Temperature Solutions
  • Single unit designed to handle wide temperature ranges and meet the demands of each stage of the hot rolling process
  • Durable IP65-rated (NEMA4) stainless steel housing withstands rolling mill ambient temperatures up to 315°C (600°F) using cooling accessories
  • Integrated galvanically isolated I/O to reduce rolling mill system installation costs
