To achieve precise cooling control, the roll barrel is ‘divided’ into zones, each of which has coolant precisely applied to it by MODULAX valve controlled spray nozzles. Each of the zonal sprays can be operated independently of the others either manually, by push button control, semi automatically by a PLC, or automatically in connection with a shape control system.
The SELECTOSPRAY system can be used in conjunction with any of the shape control systems currently available, the roll zoning being dimensionend to exactly match that of the shape metering roll involved. Zone widths for both automated and manually controlled systems are available, widths in general use being between 25 mm and 100 mm.
The SELECTOSPRAY system includes complete headers, air hoses and control cabinet.
