cooling guides for hot roll mills

GENERAL ASPECTS OF ROLL COOLING FOR HOT & COLD

For roll cooling applications of hot steel pure water is normally used as a coolant. The water is usually re-circulated in the plant and should have a sufficient filtration grade in order to prevent clogging of the nozzles. The maximum particle size shouldnot exceed 1/3 of the smallest nozzle internal passage.When and Why Do I Need Cooling for Three Roll Mill Rollers?,The same system can be used to heat up the rollers if hot liquid is pumped into the rollers. Our cooling/heating system requires 1/4 inch pipes according to NPT (National Pipe Thread Tapered Thread) standard. The pipe's outer diameter should be 0.540 in.Fundamentals of Roll Cooling and Control of Flatness at,degree of homogeneity in the cooling area on the roll. This is dependant on maintaining discrete cooling footprints that interact without interference or creating hot and cool bands in adjacent cooling zones whilst achieving uniform surface flow of coolant on the roll surface.
