In metallurgy industry, oxy-fuel cutting plants are employed to cut hot rolled metals.
Plants working on a continuous cycle are equipped with torches that work 24/7 at high temperatures, with a relevant stress level of the materials.
Tempco produces since many years a complete solution for the cooling of this kind of machinery, using a water circulating system and a cooling system in close-circuit.

The system is intended for installation in harsh and challenging environments, thus employing centrifugal pumps with moderate mass flow rate but high hydraulic head (5-6 bar), allowing cooling water to reach the most critical spots of the steel cutting equipment.

The cooling system, even if pushy working temperatures are not required, is a critical equipment since it is crucial in order to ensure seamless and continuous operations, so that it is engineered paying much attention to redundancy.

Heat exchangers design must in addition take account of dusty environment in steel mills, using wide margins for over-dimensioning and a special care choosing the proper geometry in the construction of parts in contact with external air.
