Hot Rolling Mill

Hot Rolling Mill
Temperature measurements are vital throughout the process to ensure product quality, uniformity, and increase production yields.

Accurate non-contact temperature measurements are made after the descaler, at the roughing and finishing stands and after the laminar cooling section before the coiler.

The use of Landscan process thermal imagers enables the customer to verify and control the overall edge to edge temperature uniformity.

By ensuring an even temperature balance across the strip you ensure uniform grain size and prevent camber issues.

The use of Landscan after the laminar cooling section allows for advanced cooling control methods like edge masking to be implemented.

Sophisticated and rugged Understrip pyrometers provide high quality temperature measurements when the top side of the strip may be obscured by black water.

AMETEK Land manufactures and supplies a complete range of non-contact temperature measuring systems designed specifically for hot metal rolling applications all over the world. All are designed to the highest standards of quality and reliability, to ensure accurate results in the harsh operating conditions of the hot mill.


Accurate temperature measurement is critical for the production of high quality steels. AMETEK Land’s non-contact infrared thermometers provide
these accurate, non-invasive measurements at all critical positions through the hot rolling mill process. Many of our sensors are unique developments as requested by our customers.

Application Note - Temperature Measurement in Metal Reheat Furnaces TEMPERATURE MEASUREMENT IN METAL REHEAT FURNACES
Reheat furnaces bring cold metal to the correct temperature for rolling, extruding or forging. For optimum quality, and to reduce wastage, the temperature should be uniform throughout the product, which requires accurate temperature monitoring. Read More > Watch the Video >

  • Applications +

    • Hot Rolling - Continuous Caster Spray Chamber
      Continuous Caster Spray Chamber

      The spray chamber cools the steel as it is cast. The environment here is extremely hostile, with high temperatures, high-pressure water sprays and steam. Solution: the dedicated Spray Chamber Probe.
