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