Steps towards a “Green Coil”: The newly developed Piroscale®

The Piroscale® is a newly developed descaling system by SMS group. Because first operating results underline the efficiency of the system in terms of energy and water consumption, the Piroscale® has the potential of being a milestone on the way to a “Green Coil”.

In future, the challenge of descaling in a hot strip mill is to continuously achieve the highest product surface quality with minimum energy consumption under changing operation conditions. That’s why SMS group developed the new Piroscale®. With the Piroscale®, energy savings of up to 50 percent will be possible. Furthermore, a very uniform descaling result will be achieved which is superior to conventional systems.

Basic design of the new Piroscale® system with the rotating nozzle heads (right). The red arrow refers to the position of the rotors in the descaler.

Descaling is required in every hot rolling plant to remove the scale before roughing- and finishing rolling to ensure an optimum surface quality. The descaling process normally requires a huge amount of energy due to high water flows at highest pressure levels.

In future, the challenge of descaling is to continuously achieve the highest product surface quality with minimum energy consumption under changing operation conditions. This is why our latest developed Piroscale® provides a rotation technology, assuring the most uniform spray energy distribution by multiple overlaps of spray impact zones at the product surface. The counter rotation of the nozzle head assures directed water and scale collection. Water pressure and rotation speed is adjustable to steel grade product speed and width. With the Piroscale®, energy savings of up to 50 percent will be possible. Furthermore, a very uniform descaling result will be achieved which is superior to conventional systems.

A reduction of non-desired water and a reduced temperature drops at strip are additional advantages of the new feature and the new system could be integrated in a new or an existing automation system with an imbedded operation and integrated performance control.  

Wolfgang Fuchs, Head of the CoC Hot Rolling Mills / Plate Rolling Mills, SMS group GmbH: “#turningmetalsgreen is our mission. Especially for the energy-intensive production of hot strip and plate, we are currently working on numerous solutions in order to minimize both resource consumption and CO2 emissions. The new Piroscale® will be an important milestone on the way to the "green coil".
