Hot Rolling Steel Mill

Industry: Steel

The challenge: Accurate end-to-end temperature measurement across reheat furnace, descaler, rolling stands and cooling zone, including view-through combustion gases, steam, water and scale.

The approach: Dual-wavelength pyrometry in the furnace and stands to correct for emissivity changes and see through obstructions, plus a long-distance dual-wavelength setup in the cooling zone for reliable measurement even with partial view and misalignment.

Outcome focus: Stable readings across harsh zones to support quality control and process consistency.
