ROLL COOLING SYSTEM
Taking into account your individual requirements and specifications we design and manufacture complete systems comprising spray valves with integrated spray nozzle, spray bars and control cabinets incl. The major bus connections.
In the field of hot and cold rolling plants, the multi-zone cooling is used for the production of steel, aluminum and non-ferrous metal sheets. This 2/2-way spray valves with the division 13, 26 or 52mm are arranged over the entire roll width to selectively cool the rolls in certain areas and thus to regulate the sheet thickness in a narrow tolerance range.
Fast switching, reliable spray valves are necessary for this process, as they are custom designed, manufactured and sold by Evertz HYDROTECHNIK.
The valves can be piloted both by means of its own medium as well as foreign media.
Standard operating conditions:
Media: emulsion, rolling oil (kerosene)
Pressures: Standard 0 to 10 bar (max up to 16 bar)
Nominal widths spray valves: DN5, DN8, DN12, DN16
Temperatures: max. Operating temperature 0 to + 70 ° C (Hot Edge and + 100 ° C.); Max. Ambient temperature: 0 to + 60 ° C
If you have a request outside of our standards, then we will develop a solution for you!
