AI Technical Summary
The existing cooling water tanks of cast rolls are prone to stress concentration, scaling, blockage and corrosion, which increases the cost of use and requires frequent repairs of the roll core.
The roller core has no water groove on its outer circle, but the inner hole of the roller sleeve is machined with a water groove. Copper or aluminum materials with better thermal conductivity are used. The roller sleeve is fixed and easily disassembled by combining screws and snap-fit structure, and the cooling water circulation path is optimized.
This achieves rapid and uniform cooling of the casting rolls, extends the service life of the roll sleeves, and reduces maintenance costs.
