CAL - Continuous Annealing Line

CAL - Continuous Annealing Line
The continuous annealing line (CAL) is used to modify the grain structure of steel through heat treatment, changing properties including hardness and strength. 

The process involves several stages, focused on controlled heating and cooling to produce steel with the required qualities. Accurate temperature monitoring and control in each zone is essential for process and quality control.

AMETEK Land has supplied the steel industry with high-quality, reliable temperature measurement solutions for more than 70 years. This experience is concentrated into our range of specialist instruments, designed to provide the essential measurements for steel makers.
