Due to constantly increasing strip quality, the cooling water valves for the work rolls in the intermediate frames of the turning zone are designed with specially adapted characteristic curves. The periodically changing width and thickness of the rolled material is controlled by a high resolution of the characteristic curve. Cooling water control valves for the hot strip rolling stand are used to increase the strip quality and continuous cooling of the work rolls.
(Recommended : ECOTROL® Series 8C, 6N)
To ensure a wide range of cooling possibilities in laminar cooling, ARCA control valves with large Kvs values and linear characteristics are used here.
Cooling water control valves
The cooling water valves ensure final cooling of the strips after rolling in the production line and forward them to the coiler system for precise winding. Thanks to specially mounted peripheral devices and the corresponding safety position of the ARCA actuators, emergency cooling is continuously ensured.

Due to steadily increasing strip quality, the cooling water valves for the work rolls inside the intermediate roll stands are designed with specially adapted characteristics. The periodically changing width and thickness of the rolling stock is controlled by a high resolution of the characteristic curve. Cooling water control valves for the hot strip rolling stand are used to increase strip quality and continuously cool the rolls.
ARCA bearing pressure control valves with modified characteristic curves are used to increase the service life of the work roll bearings within the production line. They also ensure optimum lubrication of the work roll bearings. Pressure controllers series 902 on the ARCA actuators with supporting volume boosters ensure fast reactions.
